摘　　要：潜水蒸发是陆面水量损耗的重要部分,对农作物生长有重要影响。区域潜水蒸发量的计算对区域水资源的合理配置及水均衡研究有重要意义。本文利用安徽省淮北平原151个浅层孔隙水水位监测点及周边分布的8个水面蒸发站点某月监测数据,通过arcgis并插值生成栅格文件。用阿维扬诺夫公式计算淮北平原该月区域潜水蒸发量为1.70E8 m^3;利用Visual Modflow建立淮北平原区域地下水数值模型,计算数值模型区域潜水蒸发量。两者进行比对分析,验证利用arcgis进行不同时间尺度和空间尺度上的区域潜水蒸发量这一方法的可行性。The phreatic water evaporation is an important part of the land surface loss of water,it have a major effect on crop growth. It is important that Regional phreatic water evaporation calculation to the rational allocation of regional water resources. In this paper,we use Huaibei Plain 151 phreatic water level monitoring stations and 8 water surface evaporationmonitoring stationsdata a month and interpolated to generate raster files by arcgis. Then we get the Huaibei Plain region phreatic water evaporation the month is 1. 7 E8 m3 calculatedwith Aviriyanover ＇s empirical formula; Compared the value with the result calculated by regional groundwater numerical modelestablished with Visual Modflow,we can verify the feasibility of the phreatic water evaporationcalculate method.
