The Study on the Land Use/Land Cover Changes in Three Gorges Reservoir Region Based on RS and GIS in the Last Decade

Abstract

With the construction of the Three Gorges Project, the type of land use/land cover in Three Gorges Reservoir Region changed much, at the same time, the environment of the same region changed greatly, too. There is some relationship between the land use/land cover changes and environment changes, which is the reason of the paper. Firstly, the analysis of the TM Remote Sensing images in 1995 and 2008 and other related data in Three Gorges Reservoir Region was made, then the area value of different land use/land cover type in 1995 and 2008 was extracted, the change law of different type was obtained. On the other hand, the change law of different environment parameters in 1995 and 2008 was made by querying the Statistical Data. The relationship between the Land Use/Land Cover Changes and Environment changes and the reason of the relationship were discussed at last. The Remote Sensing (RS) method provides abundant and real-time information, and Geographic Information System (GIS) has powerful functions in data processing and spatial analysis. The combination of RS and GIS has inestimable advantages compared with the traditional methods, and is highly effective in analyzing the relationship between the land use/land cover changes and environment changes in Three Gorges Reservoir Region.
