摘　　要：通过分析江苏省苏南、淮南、淮北三片各典型区的作物潜在腾发量与水面蒸发量之间的关系,提出了一种仅根据水面蒸发量采用彭曼法计算江苏省水稻作物需水量的简化方法.Southern Jiangsu, Huainan and Huaibei are investigated as model regions, where the relationship between the crop potential evapotranspiration and the water surface evaporation quantity is deeply analyzed. As a result, a Penman-based simplified method which is only based on the evaporation data is presented for calculating the paddy water demand in Jiangsu province.

关 键 词：彭曼法 A值法 作物需水量
