Study Of LUCC In The Three Gorges Reservoir Area(Taking Wushan County As An Example) Based On 3S Technology

After the impoundment of the three gorges project, the land use structure and land cover spatial distribution pattern of reservoir area changed markedly. Historical experience tells us that land resources and maintaining ecological balance is the foundation of social economy sustainable development.3S technology applied to Land- Use and Land Cover – Change( LUCC) make up for the problem of low efficiency in traditional methods. High resolution remote sensing image as the foundation information source; Geodetic GPS technique field inspection object type classification accuracy and measurement on attribute data; GIS provides a series of tools to meet the LUCC research mapping, spatial analysis, LUCC models application needs.Wushan county geological environment and the structure of land resources in the three gorges reservoir area are typical and representative. This paper chose Wushan county as the typical case study area, using the 3 s technology and other related technologies on LUCC qualitative and quantitative analysis.This paper made a research content:(1) Establish the classification system and remote sensing in the study area, and evaluate understand the quality of the translation of sign results, improve the accuracy of remote sensing interpretation signs are discussed.(2) Counted 2004, 2008, 2012 statistical data of various land types in the area, analyzes the dynamic trend of LUCC study period, and sums up the influence of the dynamic tendency comprehensive reasons.(3) Apply to class change dynamic index model research of LUCC, Using the three gorges project as the main driving force to explore LUCC driving force; using the markov model on LUCC prediction research and suitability evaluation.
