【Abstract】 For the limited of water,intending to provide some theoretical proof on tree species selection and stand density ascertainment for the vegetation restoration in arid and semi-arid region on northwest of China,based on the theory of soil-plant-atmosphere continuum,the paper studies the transpiration Characteristics of Salix Psammophila, Elaeagnus angustifolia,Caragana microphylla Lam,Atripldex canescens and the factors which affect the transpiration.The main problems discussed in the dissertation are as follows:rule of transpiration of four forest stands;the relation between water consumption and the main factors which affect it;rule of soil evaporation of four forest stands;actual evapotranspiration of each forest stands in growing season;The distribution coefficient between evaporation and transpiration in growing season of four forest stands.更多还原
