| 摘 要： | 人工灌溉是干旱地区农业生产的必要条件，而与灌溉能力相适应的排水也是农业发展的控制性要素。选择内蒙河套灌区长胜试区内两个观测点，设置4套井群布置方案。并按井流格式对各方案进行迭代计算。与试验观测数据作对比，结果表明。在水文地质条件许可的情况下，竖井排水可有效抑制土壤返盐和改善土质，并根据实验区实际情况，推荐适合本区的排水布设模式。

| Abstract: | Irrigation is essential for agricultural production in arid area, and the same is drainage corresponding to irrigation. In this paper two observation stations, in Changsheng experimental field of Hetao irrigation region in Inner Mongolia, are selected for study. Four configurtion options of drainage wells are investigated and each is analyzed through iteration computation based on well-function. Compared with observed data, the computation results show that silo drainage can effectively control soll salination and improve soil quality under acceptable hydro-geological conditions. And the drainage well configuration suitable to this study area is recommended according to the actual conditions. |

| Keywords: | evapotranspiration salt and basification silo drainage group wells well function |
