摘要: 水土保持林是防护林的一个重要林种,具有生态效益、社会效益和经济效益。水土保持林综合效益的评价是当前的一个重要课题。效益评价的方法有多种,因效益种类的不同而有所不同。效益评价的过程是,首先要建立一套完整的指标体系,确定指标体系中各要素的权重;然后通过相应的数学方法进行效益的评价计算,并在此基础上,确立水土保持林综合效益评价的评估模型。文中还对几种有代表性的评价方法和评估模型做了点评,指出了在水土保持林效益评价研究中存在的问题和今后的发展趋势.

关键词: 水土保持林, 效益评价, 指标体系, 评估模型

Abstract: Water and soil conservation forest is an important kind of protection forests, which has ecological, social and economic benefits.The evaluation on its comprehensive benefits is currently a significant topic, and the methodologies are quite different due to different interests.The evaluation process begins with constructing a set of complete index system and determining the weight of each index, then the benefits are calculated by appropriate mathematical methods, and last, the assessing models of evaluating comprehensive benefits are defined.Several representative evaluation methods and assessing models are appraised, and the problems and tendencies of research on benefit evaluation are pointed out in this paper.

Key words: Water and soil conservation forest, Benefits evaluation, Index system, Assessing models
