中文摘要	针对黑河山区草地蒸散发估算，提出了两种草地蒸散发量估算方法，即基于Penman-Monteith方程的方法和基于Priestly-Taylor方程的方法，并将这两种方法和SHAW模型作了对比分析。两种方法与SHAW模型计算精度相近，但输入变量数量比SHAW模型要少，尤其是基于Priestly-Taylor方程的方法。
英文摘要	Estimation of evapotranspiration is an important aspect in the research and computation of water balance and runoff processes in the inland river basins of the arid area of northwest China. Especially, the development of runoff models in the inland river basins meet problems in the esti-mation of evapotranspiration. However, because of lack of the measurement and researches on evap-otranspiration in the inland river basins, there are still not the effective methods to estimate evapo-transpiration in accordance with the characteristics of climate, hydrology, ecology and environment. This paper is intended to investigate the estimation methods of grass land evaportranspiration in the mountain area of Hei River Basin in the arid area of northwest China. Based on the preceding ches, this paper puts forward two estimation meth ods of evapotranspiration: one is based on Penman-Monteith equation, another is based on Priestly-Taylor equation. Then this paper makes a compar-ison between the results of the two methods and the result of SHAW model. The comparison shows that the two methods suggested in this paper ob-tain the similar results in good fitness to the results simulated with SHAW model. Contrasting to SHAW model, the two methods in this paper re-quire less parameters, especially the method based Priestly-Taylor equation is more convenient to ap-ply in the mountains of the inland river basins. Be-cause fewer observations about meteorology and hydrology, the two methods recomended in this paper are good choice in the estimation of evapo-transpiration in the mountain area of the hei River Basin.
