摘    要:本文采用小型蒸发皿对小美旱杨防护林和新疆杨防护林的蒸发效能进行了平行观测 ,并采用热平衡法对两种林网内的土壤蒸发进行平行研究 ,主要结论为 :小美旱杨防护林和新疆杨防护林均能有效地减少林网内土壤蒸发 ,但小美旱杨防护林的蒸腾耗水量高于新疆杨 ,使得小美旱杨林带对林网内的增湿降温作用较大 ,小美旱杨林带的蒸发效能高于同龄新疆杨。

关 键 词:小美旱杨(Populus popular’s)  新疆杨(Populus alba L.Var.pyramidalis)  农田防护林  蒸发效能

Abstract:In this research the evaporative effects of Populus popular's and Populus alba var.pyramidalis shelter belts were measured by miniature evaporators,and the soil evaporations of the two shelterbelts were studied by thermal equilibrium.The results showed that the both shelterbelts could reduce soil evaporation effectively in forestry network,but the evaporation of P.popular's shelterbelt was more than that of P.alba var.'s, so it made the P.popular's forest had a remarkable effects on increase of humidity and decrease of temperature. There were not remarkable differences in soil evaporation at different shelter distance in two kinds of forestry networks .
Keywords:Populus popular's  Populus alba var.pyramidalis  shelterbelt  evaporative effect  soil evaporation
