| 摘 要： | 在充分消化吸收前人成果的基础上,通过对研究区不同下垫面条件、作物种植情况及供水条件进行全面调查,将研究区划分为城区、山区、平原区3种类型区,并对每种类型区分别按水体、透水区、不透水区计算其蒸散发量,然后合并求得各类型区总蒸散发量,建立了以城区、山区、平原区蒸散发量计算为子模型的区域综合蒸散发量计算模型。

| Abstract: | The calculation method of regional land surface evaporation is based on the adequate absorbing previous achievements. In this method the research region is classed as: urban area, mountainous area and plain area by analyzing the different conditions of the underlying surface, planting covering rate and water supplies. Each kind of area is divided into sub areas such as water body, water leakage area and non-water leakage area and its evapotranspiration is calculated. The total evaporation of each kind of area can be got by integrating the value of its sub areas. Thus, with the evaporation calculation of urban area, mountainous area and plain area as the sub model, a calculation model for regional synthetic evapotranspiration is created. |
