摘要
本文以河套灌区两种同龄的新疆杨(P.albavarpyramidalis)和小美旱杨(P.popularis,)防护林网为研究对象,从动力效应、热力效应、水文效应等方面确定评价指标,并用灰色局势决策方法计算两种防护林各阶段综合效果测度值,对两种杨树防护林综合效益进行评价,为灌区农田防护林建设提供依据。综合评价结果表明:小美旱杨防护林网的主要防护效益优于新疆杨防护林网。
The Populus alba var pyramidalis and P. popularis farmland shelterbehs were used as the research object, evaluation indexes were determined. In addition, to provide references for building farmland shelterbehs in Hetao Irrigated District, multi - traget grey strategy decision method was employed to evaluate comprehensive benefit on two kinds of Populus farmland shelterbehs. The results were as follows ; Populus popular; farmland shelterbelt was superior to Populus alba L. var. pyramidalis farmland shelterbelt in comprehensive benefit.
