AHP法在防护林体系优化结构研究中的应用

On Optimum Structure of an Ecoeconomical Type of Protection Forest System on Weibei Loess Plateau

运用层次分析法（ＡＨＰ）对黄土高原渭北生态经济型防护林体系结构与配置优化进行判断。结果表明，“三北”防护林以生态效益为主，兼顾社会效益和经济效益，以防护林为主，多林种多树种结合，主要林种防护林、经济林、用材林、薪炭林的比例分别为４１１％、３１．９％、１９．１％、７．９％。可为生态经济型防护林体系建设发展规划提供优化决策依据。

The optimum structure of the ecoeconomical type protection forest system on Weibei loess plateau were analysized by AHP. The result indicated that the ecotogical benefils of“Three North”Protection Forest were the most important and the economical, ecological, social benefits should be considered each other. The protection forest categories are 41.1% for protection forest,31.9% for economical forest,19.1% for timber forest and 7.9% for fuel woods. The method and technique of the study could provide a foundment for the designing and constructuring an ecoeconomical type of protection forest system.
