清水河水库工程影响区生态系统服务价值评价

以云南省文山州清水河水库为例，对其环境影响区域内土地利用变化进行分析，全面预测研究区生态系统服务价值和变化情况。结果表明：清水河水库实施后，研究区内土地利用类型并未发生显著变化，旱地依旧是主要的土地利用类型，生态系统总体格局并未发生改变；研究期间虽然生态系统服务总价值呈上升趋势，但工程建设对多数生态系统功能价值会有一定的负面影响，因此在生产建设和管理中，要加强林地保护，尽量降低生态系统的损失；清水河水库下闸蓄水后，水域生态系统服务价值的变化将会对研究区生态系统服务总价值将产生较大影响；研究区内生态系统服务之间存在显著的协同关系。

Evaluation of Ecosystem Service Value in Qingshuihe Reservoir Impact Area

This paper analyzed the land use changes in the environmental impact area of Qingshuihe Reservoir in Wenshan Prefecture, Yunnan Province, and comprehensively predicted the value and changes of ecosystem services in the study area. The results found that the type of land use in research area was as same as before, and dry farm was still the major type, and the overall ecosystem pattern was not changed;the ecosystem service value increased after reservoir construction, however, some ecosystem function values were impacted by negative effect, which was necessary to strengthen forest land protection and minimize ecosystem losses as much as possible; water ecosystem service value would be impact the whole value after reservoir construction;there was significant synergy relationships among multiple ecosystem services in research area.
