Explore methods of destroying the natural ecological environment

(1) Foreword:

The "Ring Canal" will be an epoch-making product of Hainan Island; the "Ring Canal" will not only solve Hainan's water problems at a macro level, but more importantly It will produce huge economic, ecological and social benefits for Hainan; the "Ring Canal" fully coordinates the relationship between man and nature, is a great measure to protect the green mountains and green waters, and is the greatest capital for Hainan's sustainable development. Its canals have comprehensive functions of irrigation, water storage, water diversion, breeding, power generation, tourism, transportation, and ecological regulation. In particular, the "circular canal" will be unique in the tourism industry and unique in the world.

The landscape design of the "Ring Canal" mainly solves five major contradictions: ① The contradiction between the basic water regime and the topography of Hainan Island; ② The uneven distribution of water resources in space and time, especially in the dry season and the contradiction between social and economic development. The contradiction between the growing demand for water resources; ③ the contradiction between the large amount of water and soil erosion caused by natural characteristics and the sustainable development of the ecological economy and society; ④ the contradiction between the weakness of the flood control system and the protection of land and property; ⑤ the contradiction between the lagging function of water body regulation and Contradictions in promoting new rural construction.

The landscape design of the "Ring Canal" will have an immeasurable effect on the exploration of Hainan's ecological tourism.

(2) Abstract of the paper

The landscape design of "Ring Canal" and the research on Hainan eco-tourism are discussed from the following five aspects

(1) This article uses geography The basic viewpoint of science is to study the structural distribution of the geographical environment of Hainan Island. The direction of Hainan's topography and its annular layered structure determine the basis of the landscape design of the "Ring Canal". The "circular canal" landscape design is divided into four levels:

① The position between the platform and the terrace is the circular canal landscape, and the landscape along the coast is the main axis of canal tourism;

② Landscapes with an altitude higher than the platform are mainly mountainous natural landscapes (including Wuzhishan and Limuling areas, there are 667 peaks above 1,000 meters above sea level, and the rock mass is mainly granite);

③ Landscapes with an altitude lower than the platform Natural landscape (mainly plain natural landscape);

④ Coastal natural landscape (mainly highlighting mangrove coast and coral reef coast).

Based on Hainan’s annular layered landforms and combining four different levels of landscape design, Hainan’s eco-tourism landscapes were investigated and classified into four different levels of eco-tourism landscapes:

a. International Attractive: 5 national nature reserves (Wuzhishan, Jianfengling, Datian Eld's Deer, Yalong Bay, Black-crested Gibbon)

b. Leading features in the country: Sanya shallow sea coral reefs, Dongzhai Port Mangroves, Tongguling Reserve, Boao Water City, Dadonghai, Tianya Haijiao, Nanwan Macaque Island, Wanquan River, etc.

C. Those that can provide tourists with appreciation value: Ma'anshan, Luobi Cave, Xiangshui Bay, Wenchang Confucius Temple, etc.

D. Tourism potential: Limuling, Dazhou Island, Nanshan Cultural Tourism Area, etc.

"Ring-shaped canal" tourism is the most typical circular eco-tourism in the world. Let the world know Hainan and let Hainan go to the world.

(2) The landscape design of the "Ring Canal" focuses on the harmonious coordination and development of man and nature. The construction of the "Ring Canal" can regulate the water consumption of the three major industries. The canal can connect large and medium-sized reservoirs in 18 cities and counties in Hainan into a network distribution, which not only produces benefits in water transfer (annual precipitation in the east and west regions of Hainan The difference is 1000mm. The precipitation brought by the monsoon climate in the east can be transferred to the west through the canal), and it will produce great benefits in irrigation, water storage, power generation, breeding, water transportation, tourism, ecology, etc. It can be said that the "ring canal" It can provide a link between Hainan's ecological environment and economic development and is a pillar industry.

(3) This article reveals the organic integration of the layout of most tourist attractions in Hainan Ecological Island and the "circular canal". They reflect the most common points: ① The eco-tourism attractions in Hainan are distributed in an annular layer and are organically combined with the "ring canal" structural level. ②The connotations and functions of scenic spots and canals influence each other, complement each other, and are organically combined.

(4) The landscape design of the “ring canal” and issues that cannot be ignored in the study of Hainan’s eco-tourism. Hainan Island is a beautiful and rich island, but there are many negative factors that restrict ecological and economic development: natural characteristics have caused a large amount of serious water and soil erosion, with the water and soil loss exceeding 350km2; droughts, floods and geological disasters occur frequently; and the water quality of rivers cannot be underestimated. ; The phreatic water level in plain areas has declined; the coastal ecological environment is facing severe seawater erosion (to a certain extent, the edge of Hainan is shrinking); the ecological functions of wetlands have declined; land desertification has occurred in different regions, and green mountains and green waters face huge challenges. Negative factors are spreading. In addition to human factors, natural factors are very important factors, and the construction of the "Ring Canal" is exactly the negative problem caused by the management of water problems.

(5) The construction of the "Ring Canal" is a great initiative and the only fundamental way to solve the water problem. Through the construction of the Grand Canal, Hainan's rapid economic and social development needs for water resources will continue to be met; through the construction of the Grand Canal, it will promote the transformation of the economic growth model and promote the economic and social development to enter a scientific development track, especially the industrial structure and productivity layout. Compatible with water resources carrying capacity.

(3) Research methods

(1) Intuitive research methods: simulated landscape demonstration, comprehensive utilization of various atlases.

(2) Combine traditional survey methods with modern technological research (including aerial photo interpretation, satellite film interpretation, computer image processing, etc.) to fully collect landscape information at different levels from micro to macro, providing a basis for research and The design provides as much evidence as possible.

(3) Program research method (current situation-problems-feedback-confirmation).

(4) Evaluate the available value and conditions of the landscape design, and more importantly, consider the overall landscape design’s ability to withstand human interference and its ability to adjust itself. The evaluation of landscape is the basis of design.

(5) Introduce a feedback mechanism into the design process: that is, when the negative prediction (evaluation) of the landscape reaches a certain range, the landscape design plan is finally determined.

(2) Survey: different types of natural and cultural landscape areas across the island.

(3) Analysis: Use comparative method, analytical synthesis method, and logical thinking and reasoning method.

(5) Discussion and conclusion:

The landscape design of "Ring Canal" is an innovative scientific concept. It has been more than ten years since the issue of the "Ring Canal" was first raised at the 18th Pacific Science Congress in 1995. Colleagues from all walks of life have spoken highly of and affirmed it, but so far the leadership of the central and provincial governments has not Attention has been drawn to it, but it has not yet been approved as a project. I believe that it won’t be long before the landscape planning and implementation of the “Ring Canal” will be realized through the unremitting efforts of all parties.
