基于AHP分析法的川西北高寒沙地适生治沙灌木筛选评价研究

Screening and Evaluation of Suitable Shrubs for Sand Control in Alpine Sandy Land of Northwest Sichuan Based on AHP Analysis

摘要: 为进一步解决川西北沙化土地治沙植物材料单一的问题，在调查川西北沙生植物种质资源的基础上，采用层次分析法，构建川西北藏区高寒沙地适生治沙灌木筛选层次结构模型，从31种乡土灌木中筛选出沙棘、康定柳、杯腺柳、金露梅等8种优良适生治沙灌木，为川西北高寒沙地植被恢复治沙灌木选择提供科学依据。

Abstract: In order to further solve the problems of single plant material for desertification control in northwest Sichuan, based on the investigation of desert plant germplasm resources in northwest Sichuan, the hierarchical structure model for screening suitable sand control shrubs in alpine sandy land in northwest Sichuan was established by using the Analytic Hierarchy Process. Eight excellent suitable sand control shrubs were selected from 31 native shrubs, which can provide scientific basis for the selection of suitable sand control shrubs for vegetation restoration in alpine sandy land in northwest Sichuan.
