摘　　要：湿地生态系统脆弱性是学界研究的热点,在参考前人研究成果的基础上,以生态特征、整体功能和社会环境3个要素建立湿地生态系统脆弱性评价指标体系,采用均方差法计算各评价指标的权重值,运用灰色关联理论构建评价模型,对六盘水市明湖国家湿地公园的生态系统脆弱性进行了研究。研究结果表明,六盘水明湖国家湿地公园生态系统脆弱性属于微脆弱、轻度脆弱、中度脆弱、强脆弱和极脆弱的综合关联度值分别为0.575 0、0.749 9、0.789 0、0.634 6和0.515 2,说明六盘水明湖国家湿地公园生态系统脆弱性属于中度脆弱等级。通过评价,了解了明湖国家湿地公园生态系统脆弱性,为明湖湿地公园的进一步规划和管理提供了参考依据。The vulnerability of wetland ecological system is the research hotspot. On the basis of previous research results, the wet land ecological system vulnerability evaluation index system is established with three elements, i.e. ecological characteristics, the o- verall function and social environment, the weight of each index value is calculated by using the mean variance method, the evaluation model is established by using the grey correlation theory, and the vulnerability of the ecosystem in Minghu national wetland park in Liupanshui is studied. The research results show that, the comprehensive correlation degree value of the ecological system of Minghu national wetland park in Liupanshui to micro fragile, vulnerable, fragile, mild moderate strong fragile and very fragile degree values is 0. 5750, 0. 7499, 0. 7890, 0. 6346 and 0. 5152, respectively, which shows that the vulnerability of the wetland ecosystem belongs to moderate vulnerability degree. Through evaluation, the vulnerability degree of Minghu national wetland park in Liupanshui ecological system is understood, which provides a reference for further planning and management of Minghu national wetland park in Liupanshui.
