黑河干流山区流域月蒸发力计算模型

Monthly Evaporation Capacity Model in Mountainous Region of Heihe Mainstream River

研究西北内陆河山区流域的水文循环,对于维持区域可持续发展和生态环境的保护具有重要意义。应用数值迭代方法,对黑河山区流域平均月蒸发力与月平均气温和月降水量的关系进行了探讨。结果表明,山区平均月降水量、月平均气温和月蒸发力之间存在着复杂的非线性关系,降水和气温都是影响蒸发力的一个综合因子。

Making clearness of the hydrological cycle process of mountainous watershed is very important for the sustainable development and ecological environment protection of the inland river basin in Northwest China.Using numerical methods,we create several statistical models to calculate the monthly evaporation capacity of Heihe mountainous watershed.The results show that the monthly average air temperature,the monthly evaporation capacity and monthly precipitation has a highly nonlinear relationship between each other.Precipitation and air temperature both are the comprehensive factors that effect the variation of the evaporation.
