基于土地利用变化的生态系统服务价值评估——以赣州市全南县为例

Economic Evaluation of Ecosystem Service Based on Changes of Land Use——A Case Study of Quannan County,Jiangxi Province

应用Costanza生态系统服务价值计算公式和谢高地等的中国陆地生态系统单位面积生态服务价值表,对江西省赣州市全南县1996～2005年土地利用变更数据进行分析,评估了全南县生态系统服务价值的变化。结果表明:全南县土地利用的变化主要是生态退耕和农业结构调整的结果,其中林地对生态系统服务价值的贡献最大。

The objective of this paper is to analyze the changes of land use and to evaluate the ecosystem service value（ESV） of Quannan county in Jiangxi province based on ESV computing formula and ESV coefficients.The following results and conclusions were obtained： the changes of land use mainly resulted from the implementation of returning cultivated land to forestland and the adjustment of agricultural structure,and the ecosystem service of forestland had the greatest contribution to the increasing of total ESV of this county.
