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.

Key words: coastal shelterbelt, evaluation methods and selection, protection efficiency, Hainan
