摘要
湿地生态系统健康评价已成为21世纪湿地科学前沿研究领域的热点话题。以莫莫格湿地作为评价对象,基于PSR模型,选取22个评价指标建立指标体系,应用模糊综合评价法对莫莫格湿地生态系统的健康状况进行评价。结果表明:莫莫格湿地生态系统健康综合评价指数为0.7378,处于第Ⅱ等级(健康)状态,制约莫莫格湿地生态系统健康的主要因素是社会经济发展水平、化肥使用强度、湿地补水保证率、湿地水质、环保投资指数等方面。
Research on wetland ecosystem health assessment has become a hot topic in the field of wetland science in the 21 st century. In this manuscript, based on Pressure-State-Response model, we selected 22 indicators to construct the assessment system, using fuzzy comprehensive assessment method to evaluate the health of Momoge wetland ecosystem. The results showed that, the comprehensive health assessment index of Momoge wetland ecosystem was 0.7378, indicating a Ⅱ level（healthy）, main restraining factors were socioeconomic development, intensity of fertilization, wetland water replenishment, water quality, investment index of environmental protection.
