摘要
根据互助南门峡国家湿地公园现状,从湿地基本特征、湿地功能和湿地可持续发展3个方面选取25个评价指标,构建了湿地生态评价体系,采用层次分析法对互助南门峡国家湿地公园湿地生态进行评价。结果表明:互助南门峡国家湿地公园生态综合评价指数CEI为0.7428,等级为良,湿地生态良好。25个指标层评价指标中,12个指标评价等级为优,11个指标评价等级为良,生物多样性指数和社会经济承载力评价等级为差。在全局权重分析中,自然环境的水文条件权重值最大,说明湿地水文是决定湿地生态质量的重要因素。因此,保护湿地基本特征、加强生物多样性保护力度及降低社会经济承载力,是保证互助南门峡国家湿地公园生态系统稳定与可持续发展的关键。
According to the current situation of Huzhu Nanmenxia national wetland park,25 indicators were selected from 3 aspects covering basic characteristics of wetlands,wetland functions and sustainable development of wetlands,and a wetland ecological evaluation system was constructed.The wetland ecology of Huzhu Nanmenxia national wetland park was evaluated by using hierarchical analysis.The evaluation showed that the comprehensive ecological index(CEI)of Huzhu Nanmenxia national wetland park is 0.7428,rated as good,indicating good wetland ecology;among the 25 indicators,12 are rated as excellent;11 are rated as good;while the biodiversity index and socio-economic carrying capacity are rated as poor;In the analysis of overall weight,the hydrological conditions of the natural environment have the largest value,indicating that wetland hydrology is an important factor in determining the ecological quality of wetlands.Therefore,keeping the basic characteristics of wetland,strengthening biodiversity conservation and reducing the socio-economic carrying capacity are the keys to ensuring the stability and sustainable development of the ecosystem of Huzhu Nanmenxia national wetland park.
