摘要
湿地是世界上具有独特结构和功能的生态系统,其健康评价是当前学界研究的焦点和热点,目前尚没有统一的评价指标和方法。从明湖国家湿地公园的实际情况出发,根据压力、状态和响应3个方面选出19个指标,建立湿地生态系统健康评价指标体系,健康评价标准分为很健康、健康、亚健康、不健康和疾病共计5个等级;采用熵值法得到各评价指标的权重,运用综合指数法计算出湿地生态系统的健康指数。结果显示,明湖国家湿地公园生态系统为亚健康等级;分析了湿地生态系统健康的影响因素,以期为明湖湿地生态系统的建设和规划提供科学参考。
The wetland is an ecosystem for its especial structure and function in the world. Its health assessment is a key point in the academic field, but there is no uniform assessment indicator or method at presen. According to the actual situation of Minghu National Wetland Park, a health assessment indicator system of wetland ecosystem is set up. This system contained 19 indicators, which was chosen from three aspects of pressure, status and response. Based on these indicators, the health levels of wetland ecosystem were divided into 5 levels, which were very health, health, sub-health, unhealth and disease. The weight of each assessment indicator was quantified by the entropy evaluation method, and the health indexes of wetland ecosystem were calculated by the comprehensive in- dex method. The result showed that the health level of ecosystem in Minghu National Wetland Park was sub-health. To provide the scientific reference for the construction and design of Minghu wetland ecosystem, the indicators which could infect its health level were analyzed too.
