煤粮复合地区生态系统服务价值变化研究--以邹城市为例

Study on Changes of Ecosystem Service Value of Overlapped Area of Coal and Crop—— A Case Study of Zoucheng City

根据Costanza等人对全球生态系统服务价值的测算结果,分析了1996—2003年邹城市土地利用和生态系统服务价值变化。结果表明,邹城市的耕地、园地和林地土地面积在减少,建设用地和水域用地面积在增加。由于水域单位面积生态系统服务价值较高,7年间邹城市区域生态系统服务价值处于增加状态。邹城市生态系统服务价值从1996年的95.9704×106美元增加到2003年的104.5830×106美元,7年间增加8.6126×106美元,变化率达到8.97%。

Based on Costanza＇ s evaluated result about the value of the world＇s ecosystem services,this paper analyzed the changes of land use and ecosystem services value from 1996 to 2003 in Zoueheng City.Through the study,the authors found that the cultivated land,fruit land and wood- land were decreased, but the building land and water area were increased. Because the water area had a high unit ecosystem services value, the value of ecosystem services was increasing from 1996 to 2003 in Zoucheng City. Ecosystem services value was increasing from 95. 9704 million US dollars in 1996 to 104.5830 million US dollars in 2003 .The increasing rate of ecosystem services value was 8.97%.
