摘要
从模型角度阐述了计算区域蒸散量的机理,对用遥感估算法、互补关系法和水量平衡法进行估算区域蒸散量的方法分别进行了分析,并针对不同区域蒸散量计算方法做出了综合系统的评价。
Models to estimate the regional evapotranspiration were discussed. The theories of estimating regional evapotranspiration by remote sensing estimation, complementary relations and water balance were studied differently. Integrated evaluation was given to each method.
