摘要: 简要回顾生态系统健康概念的产生及发展历程,着重分析总结湿地生态系统健康的评价指标。针对其指标难以定量化、针对性不强的问题,以洪泽湖及其各支流小流域湿地生态系统为研究区域,运用压力-状态-响应(PSR)分析模型及层次分析法,尝试给出了针对具体湿地生态系统的健康评价指标体系。体系共分为3层30个指标,较全面地涵盖了生物物理、社会经济、人类健康等不同范畴。 |

Abstract: Following a comprehensive review of the progress of ecosystem health oncept,the paper focused on the analysis of the indexing system of wetland ecosystem health assessments and shortfalls,taking Hongze Lake as studied area.Accordingly,PSR model and AHP method were used to map out an indexing system of wetland ecosystem assessment in the Hongze Lake region,a 3-tiered system,with a total of 30 indices,including biophysical,socioeconomic and human-health components. |
