福州市建成区生态系统健康评价研究

Study on the Assessment of Ecosystem Health of Fuzhou Built-up Area

生态系统健康对可持续发展和环境管理具有重要的指导作用。选取福州市建成区为研究对象,借助ArcGIS平台,对2010年福州市建成区ETM+遥感影像进行解译,提取土地利用信息,结合辅助数据,建立生态系统健康评价的压力—状态—响应(P-S-R)模型,定量评价福州市建成区生态系统的健康状况,结果表明,福州市五区中生态系统健康综合指标处于一级的是马尾区,处于三级的是鼓楼区、仓山区、晋安区,处于五级的是台江区,二级和四级空缺。

Ecosystem health has an important guiding role in sustainable development and environmental management. Fuzhou built up area was selected as the study object, interpreted the 2010 ETM＋ remote sensing images of Fuzhou bUilt-up area with the Arc GIS platform, extracted land use information, and established P S-R model of ecosystem health assessment combined with auxiliary data. Then the ecosystem health status was quantitatively evaluated. It turned out that Mawei region was in the first level of the ecosystem health comprehensive index, Gulou region, Cangshan region and Jin＇an region were in the third level, Taijiang region was in the fifth level. None was in the second and forth levels.
