Abstract:

Beipan River (BPR) Grand Canyon National Wetland Park was taken as the research object. The influences of land use change due to wetland park construction on the ecosystem service value were discussed using field survey and ArcGIS as the research methods. Meanwhile, the key factors which can influence the ecosystem service value were analyzed through sensitivity analysis. The results showed that woodland area increased in large while arable land and other land area decreased in the study area after the implementation of the wetland park planning. The change of land area caused the value increase of total ecosystem service from 155.20 million yuan to 168.57 million yuan. The results of sensitivity analyses were less than 1, indicating that the ecosystem service value was robustness.

Key words: Ecosystem service value, Land use, Ecologically fragile zones, Beipan River

摘要:

以贵州北盘江大峡谷国家湿地公园为研究对象,基于实地调查和ArcGIS探讨了湿地公园规划建设前后土地利用变化对生态系统服务价值的影响,并对影响生态系统服务价值的关键因素进行敏感性分析。结果表明:湿地公园规划建设前后,研究区林地面积大量增加,耕地和其他土地面积减少,导致生态系统总服务价值由15520.71万元增加到16857.40万元,增幅达8.61%;敏感性分析结果均小于1,表明生态系统服务价值具有稳健性。
