摘要

在测定分析黄家二岔小流域内不同林种蒸腾强度日变化、季节变化特征的基础上，研究并建立了光照、气温、相对湿度、风速和地温等环境因子对蒸腾作用影响的回归模型。结果表明：该地区落叶松和刺槐林生长季节的蒸腾耗水量是同期降雨量的107.9%～119.5%

土壤的降水输入量不能满足灌乔木林地的蒸腾消耗，从而影响其正常生长。柠条、沙棘等灌木树种，其蒸腾耗水量占同期降雨量的61.66%～66.1%

土壤的降水输入量能满足灌木林地的蒸腾消耗

Abstract

The of daily variation and the seasonal variation of transpiration intensity of different trees are analyzed. The regression model that explains the influence of illumination

air temperature

relative humidity

wind velocity and ground temperature on trees transpiration is set up. The results indicated that the water consumption for trees transpiration in the growth season of larch and locust is 107.9%～119.5% of the same term rainfall

the imported precipitation of the soil can not satisfy the needs of the consumption of the arbor

and hold up their normal growth. The water consumption for the transpiration of Caragana Korshinskii and Hippophae rhemnoides is 61.66%～66.1% of rainfall in the same tern

the imported precipitation of the soil can satisfy the needs of the consumption of shrub forest land.
