- Abstract:
-
Based on the analysis of the land-use change in Three Gorges Reservoir Area (Chongqing) from 1995 to 2000, the ecosystem services value is calculated. The purpose of this paper is to examine the effects on ecosystem services value(ESV) in 1995 and 2000 according to the concrete analysis of the land use of the Three Gorges Reservoir Area (the part of Chongqing).The methods are based on ESV computing formula and ESV coefficients.The result shows that from 1995 to 2000, the area of woodland,grassland,water area and unutilized land decreased,while farmland and built-up land increased, and the total value of ecosystem services declined from 54.387 9 billion yuan in 1995 to 54.670 65 billion yuan in 2000,with the net decline of 0.286 14 billion yuan in 5 years in the study area and the sensitivity analysis suggests that these estimates are relatively lacking in elasticity,so the result is credible.
