| 摘 要： | 本文针对无径流深观测资料地区的实际情况，考虑了水田、旱地、水面积和不透水层地面面积比重，建立了相关计算公式推求陆地蒸发量。并选择了几个有实测资料的大型水库或水文站，利用建立的公式推求多年平均陆地蒸发量，与实测成果进行对比，计算结果的误差最大值只有1．77％，具有相当高的精度，可满足实用要求。

| Abstract: | In view of the fact about observation data lack of runoff depth, the article considers the area proportion of the paddy field, the dry land, the water and no water seepage layer and establishes the relevant calculation formula for ascertaining evaporation volume of the land. It selects several large reservoir and hydrological station with on--the--spot survey data, makes use of the formu- la for calculating the average evaporation volume of the land for several years, compares to the result of on--the--spot survey and the error is only 1.77% at most. Its precision is quite well and can satisfy the demand of the practical application. |

| Keywords: | Evaporation volume of the land precipitation quantity and balance of water amount |
