摘要
文中以灌区农田防护林为研究对象,对灌区两种杨树两种主林带间距内的防护效益、经济效益、节水效益方面选择若干指标,应用层次分析法(AHP)分两个时段对四种农田防护林模式进行综合效益评价研究。结果为主林带200m间距内综合效益优于100m间距内;小美旱杨防护林网优于新疆杨防护林网。
In the paper, farmland shelterbelts in the irrigation distract were taken as study object. Comprehensive evaluation on the protect effect, economic effect and water saving effect of farmland shelterbehs under two kinds of Poplars was done by the Analytic Hierarchy Process. The results of study showed P. Popularis sheleter forest is superior to P. alba var. pyramidalis sheleter forest. 200m of the distance space between shehbehs is superior to 100m＇s.
