- Abstract:
-
To analyze the rule of land use structure and the ecological value change of four kinds of land (farmland, forest land, grassland and water areas), dynamic degree model and ecological service value model was used. The land use data of Three Gorges Reservoir Area in 1996, 2000 and 2005 were used. Some interesting and significant findings have been obtained. (1) During 1996—2005, the areas of forestland and water areas had been increasing, on the contrary, the areas of farmland and grassland had been decreasing. While the increase rates of forestland and water areas are fast, the decrease rates of farmland and grassland are slow. (2) The land ecological service values of three gorges reservoir area in 1996, 2000 and 2005 were 48.59 billion yuan, 72.63 billion yuan and 90.22 billion yuan, respectively, and the value of forestland played a leading role. (3) Economic development can affect regional ecological value promotion, especially urbanization, playing the most obvious negative role. (4) Changes in ecological service value division are relatively obvious, but changes in high value division and low value division are small. (5) From the perspective of the internal structure of ecological service value, water conservation function plays a leading role.
