摘要

在全面调查研究榆林沙区综合治理防护林体系基本特征、经营现状及社会经济状况的基础上

选取对榆林沙区综合治理防护林体系建设有重要影响的生态、经济、社会3类20个指标

应用层次分析法对该区域综合治理防护林体系效益进行了评价研究。结果表明

经过10a的治理和建设

其综合效益由1995年的较差提升到了2005年的良好水平;其中生态效益由1995年的较差提升到了2005年的良好水平; 经济效益则由1995年的较差提升到了2005年的优秀水平;只有社会效益变化较小

基本保持了中等水平。因此

生态环境建设仍然是榆林沙区经济建设和社会发展的首要任务。

Abstract

The study of comprehensive treatment of shelterbelt system and its benefit evaluation in Yulin sandy area has been accomplished by using the analytic hierarchy process (AHP).The characteristics of the shelterbelt and its management status

as well as the social economic situation in the area were investigated. Twenty indexes in the 3 categories of ecology

economy

and situation were selected.The result indicated that ecological benefits

economic benefits and the comprehensive benefit were improved significantly from (bad) grade in 1995 to better grade in 2005

but social benefits were kept in general grade.Ecological bene-fits were improved from had grade in 1995 to better grade in 2005. Economic benefits were improved signifi-cantly from bad grade in 1995 to best grade in 2005. However

social benefits in 2005 were kept nearly in the same stage as in 1995. So environment construction is still a primary mission of economic construction and social development in Yulin sandy area.
