摘　　要：应用层次分析法和熵权法,选择生态区位及代表性、生物多样性、物种稀有性、自然性、规模与分区适宜性5个方面的15个指标,构建了国家湿地公园保护价值评价指标体系,对湖南省60个国家湿地公园进行评价.结果表明:湖南省国家湿地公园保护价值总体较高,评分值在67.64以上(高保护价值)的国家湿地公园有37个,占61.7%,其中评分值在77.72以上(很高保护价值)的国家湿地公园有12个,占20.0%.湖南省国家湿地公园保护价值的年际变化呈离散状,规律性不强,但总体上仍呈现降低的趋势.湖南省国家湿地公园保护价值以70分等值线为界,形成了东西2个高分值密度区和3个高分值点、中部1个低分值密度区和4个低分值点.生态区位条件、资源禀赋条件和规模大小是湖南省国家湿地公园保护价值的决定因素.This paper put forward an evaluation logical location and representation, biodiversity, index system which included 5 aspects such as ecospecies rarity, naturality, scale and partition suitability as well as 15 indicators to assess the protection values of 60 national wetland parks in Hunan Province, China. Analytic hierarchy process （AHP） and entropy method were used in this evaluation index system. There were 37 national wetland parks （ accounting for 61.7% ） keeping high protection values with scores of greater than or equal to 67.64 points, and 12 national wetland parks （accounting for 20.0%） keeping very high protection values with scores of greater than or equal to 77.72 points. Although there was a discrete and rare regularity of the inter-annual variation, these values still showed a decreasing trend in general. From the space point of view, 70 points isogram divided the national wetland parks of Hunan Province into two high score areas and three high score points in the west and east area, and one low score area and four low score points in the middle. Ecological location, resource endowment and scale were the decisive factors for the conservation values of national wetland parks in Hunan Province.
