摘　　要：[目的]为了深入了解和更好地开发应用湖南南山国家公园野生乡土地被植物资源。[方法]采用野外调查和查证相结合的方法,运用层次分析法建立定性与定量相结合的综合评价模型,对湖南南山国家公园60种野生乡土地被植物资源的开发利用价值进行综合评价。[结果](1)60种野生乡土地被植物隶属于40个科56个属,以菊科(6属6种)、唇形科(4属4种)、百合科(3属4种)、景天科(2属3种)、鸢尾科(2属3种)等居多。(2)评价模型准则层中,生长特征(0.438)和观赏特征(0.420)的权重值较高;指标层中,生长势(0.189)、繁殖能力(0.144)、花观赏性(0.123)和分布范围(0.105)的综合指标权重值较高(均大于0.100)。(3)在60种野生乡土地被植物资源中,Ⅰ级优等22种,Ⅱ级良好24种,Ⅲ级一般14种。[结论]该评价体系能够准确反映湖南南山国家公园野生乡土地被植物资源特点,为该区域及相似条件的地区野生地被植物资源的筛选应用提供参考。[Objective]It is to fully understand and potentially utilize the wild native groundcover plant species in Nanshan National Park of Hunan Province.[Method]Using the method of field investigation and verification,a comprehensive evaluation model combining qualitative and quantitative analysis was established by using the analytic hierarchy process(AHP)model to comprehensively evaluate the development and utilization value of the 60 wild native groundcover plant resources in Nanshan National Park of Hunan Province.[Result](1)The 60 wild herbaceous flower species belonged to 40 families and 56 genera,most of which were Compositae(6 genera 6 species),Labiatae(4 genera 4 species),Liliaceae(3 genera 4 species),Grassulaceae(2 genera 3 species)and Iridaceae(2 genera 3 species)et al.(2)The weight values of growth features(0.438)and ornamental features(0.420)were higher in principal level of structural model for comprehensive evaluation;the composite factors weight values of growth potential(0.189),reproductive capacity(0.144),flower ornamental(0.123),and distribution range(0.105)were higher in factor level(all more than 0.100).(3)In the 60 wild native groundcover plants,there were 22 species of excellent groundcover in levelⅠ,24 species of good groundcover in levelⅡ,and 14 species of average groundcover in levelⅢ.[Conclusion]The evaluation system can accurately reflect the characteristics of wild native groundcover resources in Nanshan National Park of Hunan Province,and provide reference for the selection and application of wild native groundcover resources in this area and similar areas.
