摘要
黄河三角洲湿地是我国暖温带最完整、最广阔、最年轻的湿地生态系统。文中以遥感数据为基础,基于压力-状态-响应框架构建湿地生态系统健康评价指标体系,并运用熵权模糊物元的方法对研究区东营市河口区和垦利县湿地进行评价。研究表明,1997年、2001年、2006年的生态系统健康评价综合得分分别为0.6388、0.7361和0.8586。
Wetland in the Yellow River Delta is the most complete,widest and youngest wetland ecological system in warm temperature zone of China.In this study,based on remote data,ecosystem health indicator system was built based on P-S-R frame,and Fuzzy matter-element evaluation model is introduced to assess the wetland ecosystem health.It is shown that the comprehensive score of assessment of ecosystem health respectively was 0.6388,0.7361 and 0.8586 in 1997,2001 and 2006.
