摘要
分析了流溪河流域白云区段生态系统的景观变化和生态环境现状,依据该段的土地详查数据(1993年)及其土地利用变更调查数据(2001年末),引用Constanza等对全球生态系统服务单位公顷价值的平均估算结果,对流溪河流域白云区段生态系统服务价值进行评估;2001年流溪河流域白云区段生态系统服务的总价值为85190050.43美元,折合人民币70700.75万元,相当于该区域同期GDP的6.22%;由于存在一些影响核算结果准确性的因素,该结果是粗略与保守的估算。

Based on the analysis of the characters of ecosystem services in Baiyun section of Liuxihe river basin and environment in present,the paper evaluated the ecosystem services in Baiyun Section of Liuxihe River Basin by using Constanza`s method. The result showed the value of ecosystem services in Baiyun Section of Liuxihe River Basin in 2001 was $85 190 050.43,equal to 70 700.75 104 RMB and 6.22% GDP.
