Effects of Land Use Change on Ecosystem Service Value in Huan'an City
Based on remote sensing interpreting data of Huai' an City in 1988,2000 and 2005,adopting Costanza and ecosystem service value coefficient proposed by Xie Gaodi,effects of land use change on eco-system service value in Huai' an City during 1988-2005 were studied.The results showed that total ESV decreased 44.87 × 108 yuan.The decrease of the ecosystem service values was mainly responsible to the dramatic expansion of construction land and the reduction of water bodies and forests.Therefore,we should increase the cultivated land and construction land through rural land remediation,rather than take water bodies and forests.
