Essay on environmental protection of Xixi Wetland

Hangzhou, Zhejiang is called "Paradise on Earth" by the world. The great poet Su Dongpo once said, "There are "Paradise, with Suzhou and Hangzhou below" reflects the paradise-like beauty of Hangzhou. Hangzhou has many scenic spots since ancient times, such as West Lake, Lingyin Temple, Feilai Peak, etc. In 2004, Hangzhou added another scenic spot: Xixi Wetland.

Introduction to Xixi Wetland

Xixi National Wetland Park is located in the west of Hangzhou City, less than 5 kilometers away from the West Lake. It is a rare secondary wetland in the city. It is rich in ecological resources, pristine natural landscape, and profound cultural heritage. It was once known as the "Three Wests" of Hangzhou together with West Lake and Xiling. It is currently the first and only national wetland in China that integrates urban wetlands, agricultural wetlands, and cultural wetlands. garden.

The success of Xixi lies solely in water. Water is the soul of Xixi. About 70% of the area of ??the park is rivers, ponds, lakes, swamps and other waters. As the saying goes, "a stream and a stream of smoke", six rivers in the entire park intersect criss-crossing each other, with numerous branches and fish scales scattered among them. It looks like a fish pond, forming a unique wetland scenery in Xixi.

The most important thing in Xixi is ecology. In order to strengthen ecological protection, three ecological protection zones and ecological restoration areas have been set up in the wetland: Feijiacuo, Xialongtan and Chaotianmuyang. There is a wetland science exhibition hall at the entrance. There are three bioremediation pools and a wetland ecological viewing area in the park. Xixi is also a paradise for birds. There are many bird-watching pavilions in the park, presenting visitors with a magnificent view of birds flying happily.

Xixi’s humanities have a long history. Xixi has been a place of seclusion since ancient times, and is regarded by literati as a pure land on earth and a paradise. Qiuxue'an, Bo'an, Meizhu Villa, and Xixi Thatched Cottage were all idiosyncratic businesses created by many literati in history, and they left a large number of poems and essays in Xixi. The ancient stage under the century-old camphor tree in Shentankou is said to be the place where the Northern School of Yue Opera premiered.

Xixi folk customs are honest and simple. The Dragon Boat Festival held every year during the Dragon Boat Festival in Shenzhen Tankou has a long history and unique form, and is known as the "Flower Dragon Boat Festival". The "Xixi Family" and "Mulberry Silkworms and Silk Stories" near Yanshui Fishing Village reproduce the farm life and labor scenes of the original residents of Xixi, allowing more people to know and understand the typical folk customs of the water town.

Definition of wetland

Since there is no clear boundary between wetland, water and land, and different disciplines have different research focuses on wetland, the definition of wetland has always been divided.

The Ramsar Convention adopts a broad definition of wetlands, which refers to swamps, wetlands, peatlands or water areas, whether natural or artificial, permanent or temporary, with static or flowing water, or Bodies of fresh, brackish or salt water, including waters whose depth at low tide does not exceed six meters. This definition includes the narrow sense wetland area, which is conducive to forming a narrow sense wetland and nearby water bodies and land into a whole for easy protection and management.

Wetland research activities tend to adopt a narrow definition. In 1979, the U.S. Fish and Wildlife Service redefined wetlands in the article "Classification of Deep-water Wetland Habitats in the United States" as: "the intersection of land and water, where the water level is close to or at the surface of the ground, or there is a shallow Stratified water has at least one or more of the following characteristics: (1) At least periodically planted with aquatic plants; (2) The bottom soil is mainly wet soil; (3) During the annual growing season, the bottom layer is sometimes flooded with water." The definition also refers to the boundary between lakes and wetlands at a water depth of 2 meters at low water levels. According to this wetland definition, the world's wetlands can be divided into more than 20 types. This definition is currently accepted by wetland researchers in many countries.

The hydrological conditions of wetlands are the decisive factor in wetland attributes. The source of water (such as precipitation, groundwater, tides, rivers, lakes, etc.), water depth, flow patterns, and the duration and frequency of flooding determine the diversity of wetlands. Water has a profound impact on wetland soil development. Wetland soil is usually called wet soil or sedimentary soil

Function of wetland

The function of wetland is multifaceted. It can be used as a direct water source or to supplement groundwater, and it can effectively It can control floods and prevent soil desertification, and can also retain sediments, toxic substances, and nutrients, thereby improving environmental pollution; it can store carbon elements in the form of organic matter, reduce the greenhouse effect, protect the coast from wind and wave erosion, and provide clean and convenient transportation. Way... It is known as the "Kidney of the Earth" because of its many golden and beneficial functions. Wetlands are also a paradise for the growth of many plants and animals, especially waterfowl. At the same time, they provide humans with food (aquatic products, livestock products, grains), energy (water energy, peat, firewood), and raw materials (reeds, wood, medicinal plants). ) and tourist places are an important basis for human survival and sustainable development.

Material production function

Wetlands have powerful material production functions and contain rich animal and plant resources. Qilihai Marsh Wetland is an important feed base and source of primary productivity in the coastal areas of Tianjin. According to preliminary surveys, before the 1970s, there were more than 100 species of aquatic and hygrophytic plant communities in Qilihai, including about 40 species with ecological value. There are about 10 species of mammals and more than 30 species of fish and crabs. As the most typical plant in the Qilihai Wetland, reed covers an area of ??7186 hectares and has high economic and ecological value. It is not only an important raw material for the paper industry, but also an important resource for agriculture, salt industry, fishery, breeding industry, and weaving industry. Important means of production can also play a role in preventing wind and floods, improving the environment, improving soil, purifying water quality, preventing pollution, and regulating ecological balance. In addition, the usable water surface of Qilihai reaches 10,000 acres, with an annual output of 2,000 tons of crabs. It is the famous origin of Qilihai crabs.

The function of regulating atmospheric components is provided by the rich plant community in the wetland. The plants can absorb a large amount of carbon dioxide gas and release oxygen. Some plants in the wetland also have the function of absorbing harmful gases in the air. Can effectively regulate atmospheric components. However, it must also be noted that wetland habitats also emit greenhouse gases such as methane and ammonia. Swamps have great biological production efficiency. During the formation of organic matter, plants continuously absorb CO2 and other gases, especially some harmful gases. The oxygen in the swamp is rarely consumed by the decomposition of dead plant remains. Swamps can also absorb dust and various bacteria carried in the air, thereby purifying the air. In addition, swamp deposits have great adsorption capacity, and sewage or industrial wastewater containing heavy metals can also be adsorbed by swamps.

The water regulation function is one of the major functions of wetlands, which makes wetlands play an important role in water storage, regulating river runoff, replenishing groundwater and maintaining regional water balance. It is a natural "water storage and flood prevention" "Sponge" can distribute precipitation unevenly in time and space, and avoid floods and droughts through the regulation of wetland throughput. Qilihai Wetland is an important flood storage and detention area in the Tianjin Coastal Plain, with a safe flood storage depth of 3.5-4m.

Swamp wetland has the function of humidifying the climate and purifying the environment, and is an important part of the ecosystem. Most of them develop in the negative landform type, where water accumulates for a long time, and dense plants grow, with roots and stems intertwined underneath and debris accumulated. Submerged swamps generally have a grass root layer of several tens of centimeters. The grass root layer is loose and porous and has a strong water-holding capacity. It can hold water 3 to 15 times greater than its absolute dry weight. Not only can it store a large amount of water, but it can also continuously return water to the atmosphere through plant transpiration and water evaporation, thereby increasing air humidity, regulating precipitation, and playing a good role in the natural cycle of water. According to experimental research, one hectare of swamp can evaporate 7,415 tons of water during the growing season, which shows its huge function in regulating climate.

Swamps and wetlands also have a purification function. They act like natural filters, which help slow down the flow of water when water containing toxins and impurities (pesticides, domestic sewage and industrial discharges) passes through the wetlands. , slowing down the flow rate is beneficial to the precipitation and elimination of poisons and impurities. Some wetland plants can effectively absorb toxic substances in the water and purify the water.

Swamps and wetlands can decompose and purify environmental substances, and play the role of "detoxification" and "detoxification", so they are known as the "kidneys of the earth". If there were no wetlands, it would be like a person having his kidneys removed. For example, nitrogen, phosphorus, potassium and other organic substances are stored by organisms through complex physical and chemical changes, or are permanently separated from the wetland through biological transfer (such as harvesting plants, fishing, etc.) and participate in greater Range loop. There are a considerable number of aquatic plants in swamp wetlands, including emergent, floating and submersible plants. They have strong ability to remove poisons and are the nemesis of poisons. It has been determined that the concentration of heavy metals concentrated in wetland plant tissues is more than 100,000 times higher than the concentration in the surrounding water. Because of this, people often use the ecological function of wetland plants to purify viruses in pollutants, effectively removing "toxins" in sewage and achieving the purpose of purifying water quality. Water hyacinth, cattails and reeds are also widely used to treat sewage and absorb heavy metals such as cadmium, copper and zinc with high concentrations in sewage. In Florida, the United States, someone conducted the following experiment. Before discharging wastewater into a river, it was first allowed to flow through a cypress swamp (a type of wetland). After measurement, it was found that approximately 98% of nitrogen and 97% of The phosphorus is removed by purification, demonstrating the wetland's amazing ability to remove pollutants. In the city of Kalkuta in India, there is a sewage treatment plant in the city. All domestic sewage is discharged into the constructed wetland in the eastern suburbs. The cost of sewage treatment is quite low, making it a global model.

One of the most important functions of swamps is to provide animal habitats. The complex and diverse plant communities of wetlands provide good habitats for wild animals, especially some rare or endangered wild animals, and are a place for birds and amphibians to breed, inhabit, migrate, and overwinter. However, although the special natural environment of swamp wetlands is conducive to the growth of some plants, it is not an ideal home for mammal populations, but birds can get special enjoyment here. Because the swamp environment covered with water and grass provides abundant food sources and good conditions for various birds to build nests and avoid enemies. There are about 200 species of birds that inhabit and appear in the wetland all year round, including swans, white storks, pelicans, wild geese, egrets, goshawks, floating gulls, herring gulls, terns, reed warblers, and grazing birds. Moreover, the wetland is a stopover for birds from Siberia and Northeastern regions migrating southward for the winter.

Adjusting the local microclimate function is also an essential function of wetlands. Wetland water evaporates into water vapor, and then falls to the surrounding areas in the form of precipitation, maintaining local humidity and rainfall.

The history of wetland environmental protection construction sites is now the protection model

Xixi Wetland This thousand-year wetland has been in danger of disappearing. Xixi Wetland is located in the west of Hangzhou City. It is a rare urban wetland in China. Naturally The terrain is a low-lying water network plain, which is composed of fish ponds, river ports, lakes, narrow pond bases and larger blocks. It is a secondary wetland with an existing area of ??10.08 square kilometers. Wetlands are a perfect blend of mountains and rivers. 70% of the area is water, and even the villages and fields can only be crossed by boat.

Xixi, together with West Lake and Xiling, was once known as the "Three Wests" of Hangzhou. With its unique Jiangnan water town scenery, it constituted a beautiful landscape in the history of Hangzhou and left a rich cultural legacy. . The Xixi Wetland was discovered in the Eastern Jin Dynasty, developed in the Tang and Song Dynasties, flourished in the Ming and Qing Dynasties, and declined in the Republic of China. It gradually became silted up and was almost annihilated.

Historically, Xixi was vast and sparsely populated, covering an area of ??60 square kilometers. In the past 20 years, cities have rapidly invaded wetlands. Local residents have enclosed the water to raise fish, build fields, set up factories and build houses. The large amount of wetland water has quickly disappeared with the evolution of urbanization. By the beginning of this century, the area of ??Xixi Wetland had dropped sharply to 10.08 square kilometers.

Within this 10 square kilometers, there are about 13,000 permanent residents and nearly 10,000 migrant residents. The residents have built about 3,000 ponds in the wetland to raise fish and turtles, and raise more than 25,000 turtles. Pig. "Human heads", "pig heads", "fish heads", and "machine heads (corporate pollution)" are sewage-discharging. The rivers in the wetland are silted up, the water quality is extremely poor, and the ecological functions are gradually lost; illegal buildings can be seen everywhere in the wetland, and the beautiful natural landscape of the wetland It no longer exists; the poems, plaques and inscriptions of the predecessors have been scattered and lost, and the "cold, wild, light and elegant" artistic conception of the wetland has gradually faded. Xixi Wetland is in danger of disappearing completely!

This situation has attracted great attention from the Hangzhou Municipal Party Committee and Municipal Government. Secretary of the Municipal Party Committee Wang Guoping has visited the Xixi Wetland many times and made decisions to save the Xixi Wetland! There are two models of wetland protection in the world: fund protection and *** protection. Xixi model is the third model. Which of the three models is more suitable for China’s national conditions?

Huang Chunlei believes that the fund protection model, whose funds come from society, is a relatively popular protection method abroad. However, this model can generally only protect small-scale wetlands. This model is not suitable for China. Doesn't work.

*** The protection model is suitable for more economically developed areas, but it is also difficult in our country.

*** Protection is only a limited protection of the core area. All 29 wetland reserves in my country adopt this model, but now they are all in trouble and struggling.

The Xixi Model is the first of its kind in wetland protection. It combines the actual conditions of the Xixi Wetland to maintain the integrity of the ecosystem, protect animals, plants and their habitats, coordinate facility construction and the ecological environment, and strengthen science education. Focusing on environmental monitoring, the ecological effect can be exerted by protecting the ecological environment and the biodiversity of the wetland ecosystem; the social effect can be exerted by carrying out knowledge education on wetland ecosystem diversity, cultural diversity and other aspects; and by strengthening legislation and other methods, correctly handle the effects of sustainable utilization, and ultimately achieve harmony between man and nature, society and the masses, history and reality, protection and utilization, and create a Xixi National Wetland Park model with win-win protection and utilization.

Xixi Wetland has a variety of animal and plant resources, which is also the focus of comprehensive protection. The area has been designated as three protected areas for ecological protection, ecological restoration, and historical relics. A wetland science exhibition hall and three bioremediation pools have been set up to integrate the best, most essential, and wetland-featured areas of the Xixi Wetland. Implementing relatively closed protection, the three major ecological areas and ecological restoration areas cover an area of ??3.25 square kilometers, accounting for approximately 94% of the total area of ??the first phase of the protection project. At the same time, we strengthened topography, sorted out collapsed pond embankments, and protected 383 fish scale ponds. By increasing the changes in the relationship between water and land, optimizing vegetation configuration, setting up waterfowl habitats, artificial bird nests and other facilities, so that more animals and plants can Find a survival and breeding ground in Xixi. Therefore, we cherish the Xixi Wetland and the fruits of labor of all relevant departments!

I think we can lower the ticket prices appropriately, add some new attractions while protecting the original attractions, protect wild animals, and contribute to the construction of Hangzhou.

Initiative to Protect the Mother River

Students:

The Yangtze River and the Yellow River have nurtured five thousand years of Chinese civilization with their broad breasts, and they have irrigated the flowers. Land; they promote a new era, they are our great mother, the motherland needs them, the earth needs them, mankind needs them, they are the arteries of the heart of the motherland.

From ancient times to the present, many people have written immortal chapters and heartfelt songs in the face of the magnificent scenery and long history of the Mother River.

Due to the progress of the times, more and more people are investing in building factories. In order to seek more profits, they are willing to destroy the environment. Trees fall one by one. The Loess Plateau that used to have dense forests and rich water and grass , with climate change and uncontrolled reclamation and grazing, the vegetation on the Loess Plateau is constantly being destroyed, the soil structure becomes loose, and the vegetation becomes scarcer and rarer, causing a large amount of yellow sand to be washed into the river, and the clear river water Lost its original beauty and clarity. Tens of millions of years ago, our mother river, the Yangtze River, was still home to many kinds of lovely creatures. However, now, due to serious pollution of the river water, busy shipping (propeller beating) and indiscriminate fishing, the Yangtze River is increasingly losing these lovely creatures. Due to this characteristic, the creatures in the Yangtze River are dying alone at a speed that we cannot predict. For the sake of those remaining creatures and for our great mother river, I propose the following initiatives:

1. Plant more trees beside the Yangtze River and Yellow River to prevent the soil from loosening.

2. Reduce water consumption.

3. Cut down fewer trees to reduce environmental pollution.

4. Take measures against soil erosion.

Let us work together. Protecting the mother river means protecting ourselves.

A is a vein, and the judgment is based on "blood flows from the branches to the trunk"

B is a capillary, and the judgment is based on "the smallest artery and vein are connected"

About 7 days after the LEEP knife surgery, the wound will start to peel off, and there will be a small amount of bleeding (if the bleeding is not as violent as menstruation, it is not a problem. This is also related to your usual exercise, not much) The bleeding seems to be more when you rest). It usually stays clean for about 20 days. At the same time, black or white scabs will appear, which is a normal reaction.

If this is not the case, it is best to go to the hospital. I only had the operation for a few days.
