Abstract:

The ecosystem service value, which is an effective tool to measure the ecosystem services, to a certain extent, reflects the relation between land use and social economic system by changing the value of regional ecosystem services. Spatial analysis of West Dongting Lake region based on massive vector and raster data were made with the aid of ArcGIS 10. Eco-economic regulation mechanism was studied by constructing the ecological economic coordination index and analyzing the characters of spatial differentiation of eco-economic harmony degrees between land the ecosystem service and economic development. The results are shown as follows: (1) The ecosystem service value of West Dongting Lake area decreased from 1292.13×106 yuan in 2000 to 953.03×106 yuan in 2011, a reduction of 339.10×106 yuan. (2) In the whole study area except Taoyuan, 6 counties have low intensity conflict in the whole research period, which are Changde, Anxiang, Hanshou, Lixian, Linli and Jinshi. All this shows that there are conflicts and the potential crisis between the economic and social development. (3) In terms of spatial differentiation, the ecological economic coordination of land use from 2000 to 2008 and 2008 to 2011 is basically a state of low intensity conflict, and that from 2008 to 2011 was a potential crisis in space. It is necessary to take measures in ecological service recovery and reconstruction and control the rapid growth of the consumption demand of ecological services.
