| 摘 要： | 以三峡库区大宁河流域为研究对象，以生态系统健康理论为基础，以联合国经济合作开发署提出的P S R(压力－状态－响应)模型为基础，建立了大宁河流域生态系统健康评价指标体系，并以遥感数据为主结合少量辅助数据，提取了流域的生态系统信息。以小流域为评价单元，对每个小流域进行单因子及综合评价，结果表明大宁河流域生态系统健康状况具有垂直地带性分布规律。

| Abstract: | The investigation object of this paper is the Daninghe River Basin in the Three Gorges Reservoir Area.Based on theories of ecosystem health and the model of Pressure-State-Response built by the Organization for Economic Co-operation,the indicator system for ecosystem health assessment of Daninghe River Basin was established.This paper adopted some data of remote sensing with other auxiliary data to distil information of ecosystem.Based on the assessment unit of small watershed,the individual index and comprehensive index were evaluated.It is indicated that the condition of ecosystem health in the Daninghe River Basin has the characteristic of vertical distribution. |
