摘要： 本文讨论了等高活篱笆技术在设计、管理和效益分析等方面的原则与方法,指出应结合当地的自然条件和社会经济需求,围绕一两种主要功用来应用这种坡地持续利用技术。植物种类选择和篱笆的管理应以篱笆植物的属性、篱笆的形成及农林复合系统中各组分的和谐关系为依据。活篱笆改善生态的功能、社会经济效益宜采用费用-效益分析的方法进行评价。

关键词: 坡地, 等高活篱笆, 篱笆植物, 费用－效益分析

Abstract: This paper discusses in detail the principles and methods for the design,management,and economic appraisal of contour hedgerow projects.The authors claim that functions of the designed hedgerow should be constrained to avoid contradictions between its ecological and direct economic benefits,hedge plant properties should be emphasized in species selection,the major Purposes of hedgerow management are to promote hedge formation and to minimize negative effects of hedgerow on field crops,a cost/benefit analysis Is appropriate for both ecological and economic assessments of contour hedgerow projects.

Key words: Slopeland, Contour hedgerow, Hedge plants, Cost/benefit analysis
