摘要

Evaluation indicators system of ecological health of wetland resources and evaluation indicators system of rational utilization of wetland resources in the Yellow River Delta Nature Reserve were developed in this study. The indicators have been divided into five grades with quantitative and qualitative combination; analytic hierarchy process and Delphi method have been adopted to make comprehensive evaluation for the wetland resources in the nature reserve. Results showed that the rating for ecological health of wetland resources in Yellow River delta was 1.02, indicating relatively healthy and close to unhealthy; the rating of utilization of wetland resources in Yellow River delta is 0.73, which is generally rational. The main pressures are over exploitation of recourses, environmental pollution and soil salinization.%构建了黄河三角洲自然保护区湿地资源生态健康评价指标体系和湿地资源合理利用评价指标体系,通过定量与定性相结合的方法将指标分为5个等级,并运用层次分析法以及DPH方法对黄河三角洲自然保护区湿地资源进行综合评估.结果表明:黄河三角洲湿地资源生态健康评价得分为1.02分,属于较健康的临界值,接近疾病;黄河三角洲湿地资源合理利用评价得分为0.73分,为一般合理,主要压力来自于人类对湿地资源的过度开发、环境污染和土壤盐碱化等方面.
