| 摘 要： | 采用主成分分析,熵权法和层次分析法对海南省海防林防护效能进行了综合评价,并通过样本聚类分析对3种评价方法进行了选优,确定层次分析法中的分值评价是海防林防护效能综合评价的有效方法。用层次分析法的分值评价对海南省沿海12个市县进行综合评价,结果显示:2005年文昌市和万宁市海防林防护效能达到了良好状态,儋州市、昌江县等6个市县海防林的防护效能较差。

| Abstract: | Principal component analysis,entropy weight method and analytic hierarchy process(AHP) were used to evaluate the protection efficiency of coastal shelterbelts in Hainan Province and the best evaluation method was selected from those three evaluation methods by means of case cluster.The score evaluation of AHP was regarded as an effective comprehensive evaluation method as for coastal shelterbelt protection efficiency.Comprehensive evaluation results on coastal shelterbelt protection efficiency for 12 coastal cities and counties in Hainan Province with score evaluation of AHP showed that the protection efficiency of coastal shelterbelts for Wenchang and Wanning cities was high but low for 6 cities and counties of Danzhou,Changjiang and so on in 2005. |
