摘　　要：为验证DRAINMOD模型的准确性,该文采用泗阳县运南灌区4次降雨后农田短系列排水过程实测数据与模拟数据进行评价分析,两系列相关系数均在0.98以上,具有较好的相关性;Nash系数均在0.9以上,模型模拟效率较高,实用性较强。The paper analyses the difference between the simulation and measurement results of short series farmland drainage after four rainstorms in Yunnan irrigation area in Siyang County to test and verify the accuracy of DRAINMOD.The two series have preferable relativity with the correlation coefficient exceeds 0.98;and the efficiency and practicability of model are perfect with Nash coefficient outnumbers 0.9.
