中文摘要	以水面蒸发量为基础,利用多年的白杨农田防护林试验资料,建立了塔里木河流域白杨农田防护林蒸散量的两种估算模型,并利用白杨林实际蒸散量的测量值,分别对两种模型进行了验证.结果表明,从总体上来说,模型(I)计算精度较高,但两种模型的相对误差都不是很大,都可以作为计算塔里木河流域白杨农田防护林蒸散量的方法而使用,但要根据具体情况加以应用.
英文摘要	Many experts have studied the evapotranspiration of forest land, but few of them to take Tarim river as research area, this paper studied the Aspen shelter belt evapotranspiration of Tarim river basin. Based on the relation between the ratio of evapotranspitation to evaporation from water surfaces and the average water content of root zone, and the relation among soil moisture influence function, plant factor influence function and evaporation from water surfaces, and according to the materials of evaporation from water surfaces and soil moisture measured in Aksu water balance experimental station, this paper established two models for estimating Aspen shelter belt evapotranspiration of Tarim river basin, and made a comparison of the two models, the result revealed that the two models both had high precision, but the precision of model(1) is higher, and they both could be used to estimate the evapotranspiration of Aspen shelter belt in Tarim river basin, so actual measurement can be replaced, and much human power, materials and financial resources could be saved, and the two models also could be used to assess the soil moisture condition of shelter belt in Tarim river basin, further to offer scientific basis of the augment of water resources utilization ratio and the development of shelter belt in arid zone.
