Study On Land Use Dynamic Change And Sustainable Development Of Wanzhou In Three Gorges Reservoir Area

The sustainable development of land resources is important integrant of strategic objective of in China. Along with fast raise of population and development of economy and society, a shortage of land resources due to multi- factor has lead to worry on land ecological safe, therefore sustainable development and exploitation potentialities of land resources is certain to carry weight.The Yangtse River is the biggist rever in China,it has special strategic status. Three gorges reservoir area is located the upper reaches of the Yangtse River, where are torrential rain concentration, amount runoff, population concentration, historical background long, serious soil and water loss, strong human operation. The building of Three gorges reservoir may be will increase pressure to environment due to limited environmental capacity, so it will affect directly (?)angement of product mix of agriculture,the use land resources and regional climate. The ecological environmental protection and construction of Three gorges reservoir area is important development content of the west area, so it has special strategic status and importance due to bear safe liability of Three gorges reservoir, where it is one of the most serious natural calamity area due to landslide and mud-rock flow. Before Three gorges reservoir area is inundated , the capacity of land has almost get saturation,and the level of production is lower, the technique and mode of production is backward,the economic strength is weak, the unreasonable land use lead to damage to ecological environmental. Therefore ,the ecosystem of Three gorges reservoir area is typical weak one. The threat of ecological safe come from mainly one of land safe,so there will be serious state of affairs after Three gorges reservoir area is inundated. Due to special strategic status, The Three gorges reservoir area diffenent from other one, the experience of other area can not be copied. Therefore , it is necessary to study on suitable development mode of Three gorges reservoir area.In order to change ability of weaker sustainable development of Three gorges reservoir area, instability of ecology, promotion effectuation strategic objective of land sustainable use in Three gorges reservoir area, it is necessary to integrated control present situation , potentiality of land use and driving forces of land use change, to search main obstacle on land use, to research and analyse...
