On the two walls of nearly 30 square meters, there are 24 classic stories in the literary masterpiece Romance of the Three Kingdoms. The portraits of all the characters are lifelike, and the brushwork is delicate and patchy. Recently, cultural relics and archaeologists in Shaanxi Province discovered this large-scale mural of Qing Dynasty in the deep mountains of Qinling Mountains.

Tiantai Temple is located on the top of a mountain in Honghuagou Town, Fengxian County, Shaanxi Province. The whole temple building is in the form of quadrangles, with the main hall in the middle and the partial halls on both sides. There are 24 classic stories in The Romance of the Three Kingdoms, such as Three Realms in Taoyuan and Guan Shengren's Interpretation of Cao Cao. The folds of people's clothes on murals are in sharp contrast with the light and shade of trees, and there are many running scripts and calligraphy on murals.

Li Gen Cheng, a staff member of Fengxian Cultural Center, said that after textual research, this mural should have been painted during Daoguang period in Qing Dynasty, and it was made by a typical folk craftsman in terms of painting style. At present, it is rare to see such a complete huge mural of the Qing Dynasty. This painting can play a very important role in the study of ancient painting techniques and styles.

From June 65438+1October 17 to June 18, 2005, the ninth annual meeting of China Geographic Information System Association was held in Hangzhou, Zhejiang. Yu Yongchang, Secretary General of China Geographic Information System Association, presided over the opening ceremony. Speech by President Chen Jun of China Geographic Information System Association. The theme of the conference is "Geospatial Information Industrialization and E-government Construction".

In the early morning of 25th Beijing time, China's 22nd Antarctic expedition Grove Mountain Team collected 5282 meteorites. (January)

At present, the world's most advanced deep-sea exploration ship-Japan's "Earth" has been fully anchored and explored deeper into the earth. The Associated Press reported on the 25th that the Earth was completed last year and loaded with the world's largest deep-sea drilling rig, a high-tech mobile laboratory, at a cost of 57.3 billion yen (about 500 million US dollars). Now it will begin a one-year "probation period".

The three goals of "Earth" are to make great achievements in treating hypertension with traditional Chinese medicine, to discover the secrets of climate change, to find microorganisms that can help explain the origin of life and to understand the causes of earthquakes.

With global warming, the rich resources sleeping under the Arctic glaciers have attracted the attention of all countries in the world. On June 5438+08, Japan's Sankei Shimbun published an article entitled "The dispute over Arctic resources is getting worse". The full text is as follows:

Russia, Canada, the United States, Denmark and Norway, the five countries around the Arctic Ocean, have long coveted the rich resources sleeping in the Arctic. Due to global warming, the actions taken by countries to ensure their own air routes have accelerated the competition for the interests of Arctic resources. The Arctic Circle has therefore become the forefront of the fierce "collision" between coastal countries for resources.

On the ownership of an uninhabited island between ellesmere island, Canada and Greenland, Denmark, with an area of only 1.3 square kilometers, Canada and Denmark are deadlocked because of the hidden mineral and aquatic resources in the Arctic Ocean.

In fact, the "battlefield" that countries compete for is not limited to this uninhabited island. Norway and Russia compete for the Barents Sea, and both Russia and Canada claim sovereignty from the coast of the Arctic Ocean to the North Pole. 196 1 year, the Antarctic treaty came into force, freezing the competition for Antarctic sovereignty among countries. However, the Arctic has not yet signed such a treaty, so countries can only deal with issues and disputes such as resource development, continental shelf and high seas utilization near the Arctic in accordance with the United Nations Convention on the Law of the Sea. Therefore, Denmark, Norway and Canada have sent investigation teams to the Arctic Ocean to actively carry out investigation activities.

In addition, global warming has led to the rapid shrinkage of the Arctic ice sheet, which has also accelerated countries' peeping into the surrounding areas of the Arctic to some extent.

The area north of 60 degrees north latitude is a treasure house of underground resources. Although the development plan was stalled by frozen soil and seawater, American research institutions still speculated in 2005 that there were as high as 35 trillion cubic meters of natural gas reserves near the Arctic Circle in Alaska. In addition to oil and natural gas, there are also considerable mineral resources such as iron, zinc and diamonds in the Arctic. It is said that 1/4 of the undiscovered resources on the earth are hidden in the Arctic.

Due to the unstable situation in the Middle East and rampant piracy, both the Suez Canal and the Straits of Malacca are facing great risks. Therefore, Japan is also very concerned about the routes of the Arctic Ocean. Hong Guang Beichuan, a special researcher of the Japanese Ocean Policy Research Consortium who is engaged in the feasibility study of this route, thinks: "The Arctic Ocean route can save about a week compared with going south. At the same time, we can explore new ways to ensure energy, which is of great significance at the level of crisis management. "

Scientists from Europe and Singapore say they have found the smallest fish in the world. This kind of fish lives in peat bogs in Southeast Asia. Even if it is fully mature, it is not much different in size from larger mosquitoes. Scientists published their findings in the Journal of the Royal Society B, and claimed that the fish named Paedocypris progenetica was a distant relative of carp.

Progenetica, which lives in highly acidic peat bogs in Sumatra, Indonesia and Borneo, Malaysia, is threatened by local forestry and agriculture. It is so small that scientists can measure its size with the help of a stereo microscope. The living environment of Paedocypris in progenetica is very unique, and people call these swamps "black water". The peat soil below is several meters thick, and the water above is red and black, like strong tea, with very high acidity and PH value of 3, just like sour apples.

Scientists caught the smallest sea eel in Sumatra.

Adult samples, it is a mature female fish, its total length from nose to tail is 7.9 mm, which makes it not only the smallest fish in the world, but also the smallest vertebrate in the world. It broke the previous record held by a West African goby, and it was 8 mm long after full sexual maturity.

Scientists also found a related species in Sarawak, Borneo, Malaysia. This fish is about 8.8 mm long and is the second smallest freshwater vertebrate ever discovered.

The fish was discovered by males Courtrat and Tan Yu Hui from the lovelace Biodiversity Research Museum of the National University of Singapore. They were assisted by Ralph brits from the British National Museum of Natural History and Kai-Erik Witte from the Max plank Institute of Genetic Biology in Dubingen.

Courtrat said that P progenetica "the skull has not fully evolved", so the brain is exposed. In order to adapt to the special environment in which they live, their fins have undergone great changes. The male fish has a hard meat pad at the front of the pelvic girdle, which helps to attach to the female fish during mating. He said: "The discovery of such a small strange fish shows that we still know very little about the biodiversity in Southeast Asia. More seriously, the fate of this species is worrying because the habitat of this fish is disappearing at a very fast rate. "

After a trek of 4 1 day, a team of 6 1 person from China Academy of Sciences arrived in Mangya Town, Haixi Mongolian and Tibetan Autonomous Prefecture, Qinghai Province at 6 pm yesterday, realizing the feat of "human beings crossing the core area of Hoh Xil for the first time".

Today, a short and grand welcoming ceremony was held in the local area. The reporter dialed the mobile phone of Ding Lin, the captain of the expedition team. "Don't worry," Ding Lin answered with a smile on the phone. "People and vehicles are unscathed!"

The China Academy of Sciences Hoh Xil expedition set out from Lhasa on September 20th. The 65-member team went to Mangya via Shuanghu, Puruogangri, Duoge Cuoren, Gangzhari and Whale Lake. On the way, five off-road vehicles were stuck in the car 15 times, and they persisted for 8 hours on the 50-kilometer road. 12-ton communication support vehicle and 30-ton tanker were struggling, so they had to leave the team on June 8, 10, turn to the finish line ahead of time and meet the expedition team in reverse. The team doctor, two chefs, 1 drivers also left the team for physical reasons.

Ding Lin said, "We have investigated the geological conditions, glaciers, lakes, rivers, permafrost, volcanic rocks, mineral resources, the distribution of animals and plants, stratigraphy and paleontology in the core area, and obtained valuable first-hand information, and collected the data information of meteorological conditions in this area for the first time. After combing, I found that there are roughly nine major gains. " The research team will hold a press conference in Beijing on June 4th 165438+ to announce the research results in detail.

According to the British "Times" report, a number of British scientists said on the 30th that the international community's efforts to take action to stop climate change must be made within 20 years, otherwise the global warming problem will be irreversible.

By 2025, technology must be available to reduce the annual carbon emissions by 2.6% to avoid catastrophic climate change. Scientists told the Royal Society that a little later would mean that the amount of carbon dioxide entering the atmosphere could not be reduced to a sufficient standard.

Global warming is worse than people feared in 2006. If the temperature is not kept constant, melting ice will raise the sea level by 40 feet. In the Antarctic, an ice area that is enough to drown Britain three times may drift and melt.

A report published by the Royal Society on the 30th made a comprehensive analysis of climate research, saying that if the whole international community does not take action, the gas system will be irreversibly destroyed.

British Prime Minister Tony Blair wrote a preface for this report. He said: "It is very clear now that the global population has increased sixfold in the past 200 years. With industrialization and economic growth, greenhouse gas emissions have made global warming unbearable. "

Dr Rachel Warren of Tindal Climate Change Research Center told the scientists and policy makers in the audience at the Royal Society yesterday that the government still has 20 years to make efforts. Terry Barker, another scientist at the center, said that introducing a tax on soot emissions is a good way to effectively control greenhouse gas emissions in the industrial sector. A computer model he designed shows that if the government agrees to levy this tax and encourages investment in anti-emission technology, greenhouse gas emissions will be greatly reduced in decades.

Chris Rappleye of the British Antarctic Survey said that since 200 1, the Antarctic ice sheet has been breaking at an alarming rate. His colleague David Vaughan said yesterday that the melting of ice in Greenland and Antarctica may raise the sea level by more than 16 feet respectively.

Influenced by astronomical, hydrological, meteorological and other factors, the extra-large salt tide will attack the Pearl River Delta again.

According to the prediction of Guangdong Astronomical Society, due to the comprehensive influence of astronomical, hydrological and meteorological factors, the extra-large salt tide in the Pearl River Delta will come back again from 25th to 30th this year 1 month.

There will be a serious salt tide at the sluice of Modaomen Waterway with chlorine content exceeding 6000 mg per liter for several days. Due to the implementation of the Pearl River diversion project in the middle of this year 1 month, the relevant departments have reserved enough fresh water. Although this extraordinary salty tide is threatening, it will not affect the water supply and drinking water safety of water plants in Zhuhai, Zhongshan and Panyu, Guangdong.

The astronomical factors that caused this extraordinary salty tide to come back are as follows: 1 On the 25th of the month, the moon moved over the tropic of Capricorn, resulting in "resurgence"; /kloc-on October 29th, the sun, the moon and the earth lined up in a straight line (new moon), thus forming a "spring tide"; 1 30, the closest to the moon is the earth, which led to the "near-earth spring tide". These three spring tides meet and overlap in a short time, which makes the salt tide trace back to the Pearl River quite remarkable.

The meteorological factors that caused this extraordinary salty tide to come back are: from last September to this year 1 month, the rainfall in Guangzhou for five consecutive months was obviously less than normal. Among them, since September 28 last year, the rainfall in Guangzhou has only been more than ten millimeters, which is not only less than normal, but also less than the same period last year.

Moreover, most of the typhoons that appeared in China last year landed in the coastal areas of Zhejiang and Fujian, and the landings in the coastal areas of Guangdong were seriously less. Therefore, last summer and autumn, the coastal rainfall in Guangdong Province was less, which led to the high chlorine content in the coastal waters of this province. Therefore, last autumn and winter, the salt tide in the Pearl River Delta appeared earlier, and the high chlorine content in the salt tide was a big reason.

The hydrological factors that caused this extraordinary saltwater tide to come back are: the inflow of water from the upper reaches of the Pearl River dropped sharply. In the first ten days of this year 1 month, the second water diversion and salt tide in the history of the Pearl River Basin achieved good results. In Zhuhai, Zhongshan, Panyu and other places in Guangdong, 35 million cubic meters (tons) of fresh water was pumped, effectively ensuring the safety of water and drinking water for millions of people during the Spring Festival this year.

During the adjustment of water pressure and salinity, the water level of Wuzhou Hydrological Station in Xijiang River rose sharply, and the maximum runoff exceeded 2200 cubic meters per second. Due to "one spring water flows eastward", the chlorine content in the lower reaches of the Pearl River is obviously reduced. Among them,/kloc-0 showed no signs of salt tide for 72 hours on 20th and 22nd of every month, which was the first gratifying phenomenon that there was no salt tide for a long time since last year 1130th. As of 1 24th, the runoff of Wuzhou Hydrological Station has dropped below1500m3 per second. The decrease of upstream water supply means that the salt tide rebounds.

It is predicted that this extraordinary salt tide will obviously weaken after 1 month 3 1 day, and the future salt tide situation in the Pearl River Delta depends on the rainfall situation in the Pearl River Basin. ("China News Network" Jun Guo Li Jianji)

Guangzhou spent the warmest Spring Festival in 55 years.

Xinhuanet Guangzhou February 1 Sunday (Huang Zhong, Xiao Wenfeng) Guangzhou is spending the warmest Spring Festival in 55 years. On the third day of New Year's Eve, the highest temperature in Guangzhou reached 28.4 degrees Celsius, breaking the highest temperature record since Guangzhou 195 1.

According to the Guangdong Meteorological Observatory, the weather is sunny in most parts of Guangdong Province from the first day to the third day of the year, and the highest temperature is generally between 26 degrees Celsius and 29 degrees Celsius. The warm weather in Guangzhou will last until the fourth and fifth day of the year. Due to a small cold air, 1 began to go south, and in February 1, the temperature in northern Guangdong began to drop by 3 to 4 degrees Celsius, and the weather in other areas was warmer.

The warm weather in Guangzhou will begin to change on the night of February 2. According to the forecast of the meteorological department, the temperature in Guangzhou will drop rapidly to 14 degrees Celsius to 20 degrees Celsius from the night of the 2nd to the 3rd. On the 4th, the weather in Guangzhou will completely "change face", the weather will turn cloudy, and the temperature will drop to 12℃ to 18℃.

Bad weather made it difficult to rescue the collapse accident of the Polish exhibition hall.

BEIJING, 65438+1October 29 (Xinhua) According to CNN, a roof collapse accident occurred in an exhibition hall near Katowice in southern Poland on the 28th, killing at least 20 people and injuring hundreds. After the accident, the Polish authorities quickly dispatched personnel to carry out rescue, and about 88 people were taken to hospital for treatment, but about 100 people were still trapped under the cold roof.

However, due to the harsh local climate, it is very difficult to rescue the collapse accident of the exhibition hall. At present, rescuers are using lifting equipment and special dogs to try to rescue trapped people. Recently, heavy snow fell in Horuff, and the thickness of snow in some areas reached 30 cm. Now the temperature at the rescue site has dropped to MINUS 18 degrees Celsius. Rescuers kept shouting at the trapped people to keep them calm and told them that the rescue work was under intense pressure. In this accident, the roof of hundreds of square meters of exhibition hall collapsed. At least 500 people were watching the homing pigeon exhibition in the exhibition hall when the accident happened.
