摘要: 在分析目前各种水热平衡联系方程的基础上,采取了以径流系数α、干早指数β及特征参数θ,来反映气候和下垫面的影响,建立了水热平衡联系方程。方程的形式简单,计算方便,对于短缺资料地区估算陆面蒸发,进行估算径流也是可行的。

Abstract: On the basis of analysing various correlation equations of heat and water balance up to now, according to the connection of runoff coefficient a and drought index β and a characteristic parameter θ to reflect the effect of climate and underlying surface, the following equation was proposed, α=(1+βθ)1/θ-β, in which f=runoff, r=precipitation, E0=evaporation capacity. They are all in millimeter per year. The proposed equation in the paper is feasible and has a fairy precision after it was verified by the data from every continent all over the world, the Huanghe River basin, Nei Monggol Autonomous Region, the East China, and Hainan Island in our country.
