基于层次分析法的浙江大盘山自然保护区杜鹃花属植物资源应用价值评价

Evaluation on Application Value of Rhododendron Resources in Dapanshan Natural Reserve Based on AHP Method

基于对大盘山自然保护区杜鹃花属植物的野外调查,综合考虑观赏价值、生态学特性、应用潜力和稀有度因素,筛选出14个评价因子,构建了层次分析模型,对大盘山自然保护区9种杜鹃花属植物进行应用价值综合评价。结果表明,在观赏价值、生态学特性、应用潜力和稀有度4个影响因子中,观赏价值最能影响人们对杜鹃花属植物应用价值的评价,其次是应用潜力、生态学特性和稀有度。9种杜鹃花属植物的应用价值从高到低依次为云锦杜鹃>华顶杜鹃>杜鹃>马银花>丁香杜鹃>羊踯躅>满山红>猴头杜鹃>麂角杜鹃。文中还就杜鹃花属植物的野生资源驯化以及资源评价中约束层指标的选取等问题进行了讨论。

Based on field survey of Rhododendron resources in Dapanshan Natural Reserve,14 evaluation factors were selected in consideration of ornamental value,ecological characteristics,application potential and rare degree to construct the Analytic Hierarchy Process (AHP)model to comprehensively evaluate the application value of 9 Rhododendron species in the reserve. The results showed that ornamental value was the most important factor affecting the evaluation followed by application potential,ecological characteristics and rare degree. The ranking application values of Rhododendron resources were Rhododendron fortunei, Rhododendron huadingense, Rhododendron simsii, Rhododendron ovatum, Rhododendron farrerae, Rhododendron molle, Rhododendron mariesii, Rhododendron simiarum, Rhododendron latoucheae in descending order. The domestication of wild Rhododendron resources and the selection of constraint index in resource evaluation were also discussed.
