“三江”流域(云南部分)土地利用变化的生态环境效应研究
|
摘要
以云南省三江流域为例,通过对区域土地利用变化的生态系统服务价值的研究,分析土地利用变化对生态系统服务功能的影响及效应。土地利用的变化,最终导致了区域生态系统服务功能的整体变化。结果表明,单位面积生态系统服务功能价值中,湿地生态系统服务功能单价最高,其次为水域及森林。建设用地最低,均为负值。从地区分布看,三江流域中昆明市、大理州等单价较高,但建设用地的生态功能负效应最大值也出现在该州市。2000—2008年三江流域生态系统服务功能总价值增加1 032.13亿元,增幅为13.75%。
Based on the research for the ecosystem service value of land use change,taking Three River Basin in Yunnan Province as an example,we analyze the impacts and effects of land use on ecosystem service functions.The land utilization change has finally caused whole change of the region ecosystem service function.The results show that in the unit area ecosystem service function value,the wetland ecosystem service function unit price is the highest,followed by waters and forest.The construction uses are the least,their ecosystem service function unit prices are the negative values.With respect to the local distribution,three river basin unit prices of Kunming City,Dali states and so on are high,but constructs with the place ecology function negative effect maximum value also were found in these states or cities.The total ecosystem service value of Three River Basin increased by 103.213 billion Yuan with the rate of 13.75%.
