基于集对分析的城市人工湿地公园生态安全研究

Study on the Ecological Security of Urban Artificial Wetland Park Based on Set Pair Analysis

为了解明湖国家湿地公园生态安全的现状,从压力-状态-响应3个方面选取17个指标,建立湿地生态安全评价指标体系并确定评价等级标准,运用熵权法求出各评价指标的权重,采用集对分析法构建湿地生态安全评价模型,对六盘水市明湖国家湿地公园的生态安全进行了实例研究。结果表明,明湖国家湿地公园压力和响应要素联系度分别为0.9315和0.6529,处于较不安全等级;状态要素联系度为0.5624,属于较安全等级;湿地公园综合生态安全联系度为0.6726,属于较不安全等级。

In order to understand the current situation of ecological security in Minghu National Wetland Park , a wetland ecological security evaluation system was built in terms of pressure-state-response framework .17 evaluation indexes as well as the corresponding evaluation grade standards were proposed .The construction of the evaluation model was based on set pair analysis and the entropy method , which was used to calculate the weight coefficient of each evaluation index .A case study by using the evaluation model was conducted to research the ecological security condition of Minghu National Wetland Park in Liupanshui .The evaluation results showed that the connection degree of pressure elements, state elements and response elements were 0.9315, 0.6529 and 0.5624, respectively, indicating that the pressure level and response level were in a relative unsafe condition , and the state level was in a safe condition.And the connection degree of comprehensive evaluation of ecological security was 0.6726, indicating that the ecological security of Minghu National Wetland Park was in a relative unsafe condition and the ecological security needs to be further improved .This study provides insights into the present situation of Minghu National Wetland Park ecological safety , which can be a scientific reference for the management and construction of Minghu National Wetland Park .
