Land Development Model Of The Three Gorges Reservoir Landslide Research

Landslide is a kind of geology hazard, which has both nature and society attribute. Great achievement had been alive in the traditional landslide research domain, such as engineer geology domain. But the research about society attribute is not enough. For more research about this, this paper give the way to introject geology engineer and physical geography theories. This paper which has some examples in Zigui County of Hubei Province is under the background of TGR sluice, migration & construction in TGR, and new geological hazard investigation. Firstly, this paper study the method of landslide prevention and cure ,and the interrelation between human's activities and landslides developmen. Secondly, it proved that tract exploitation on landslide body could reduce harmful landslides and increase subsistence space. The paper completely summarize the distributing characters and cause of formation. On the basis of analyze the contradiction relationship between solid resource decrease, people capacity of circumstance, it provide that landslide body reconstruction and exploitation are very important. Furthermore, on the study of regional force tract using convertion theory and migration land-ecosystem formation microcosmic theory, it give the theory base and target to the land exploiture on landslide body. That is to say, in the geology engineer domain, it study the landslide prevention and cure theory, development direction and typical engineer technique system. In the physical geography domain, it confirm the basic principle of land convertion, ecology regulation and optimal allocation by studying the theory about regional force tract using convertion. So there should be building "protection-consumption"land-ecosystem in new migration downtowns, and "protection-production"land-ecosystem in villages, in the geography layer of 175~500m height of TGR. Then taking the engineer technique of Liangguansuo Landslide in Xiakou town and Xintan Landslide in Quyuan town as great examples, the penman drew a conclusion that two land exploiture patterns about landslide body in downtowns and villages of TGR. And these patterns could be checkout and popularized. These work are very important not only to theory development, but also to these migrant in TGR. This paper has very important reality significance to migration subsistence and continuable development.
