摘要
选用淮河流域及其周边的 1 0个气象站的 3 5年气象资料和 2 9个蒸发站的 3 5年月蒸发资料作分析 ,同时对Dalton公式、Penman公式作了简化 ,进而提出了具有较为明确的物理基础的淮河流域分区蒸发模型 。
In many conventional hydrological models,potential evaporation is estimated by pan evaporation. However, this method is not suitable for large scale modeling. So a study is made in depth to simulate potential evaporation. A 35 years series of monthly data of ten weather stations and twenty nine evaporation stations in and nearby the Huaihe basin are selected for analysis, which shows a regional distribution regularity and correlation between monthly evaporation and seven meteorological factors significantly. Based on the recommendation and comparison of several models, a simplified method to estimate potential evaporation is proposed and the method is suggested to be applied to the Huaihe basin modeling in HUBEX.
