摘要
为研究控制排水措施对农田地下水位的影响,在湖北省荆州市四湖工程管理局丫角排灌试验站进行了测坑控制排水试验,并利用DRAINMOD模型对不同试验方案下地下水位进行数值模拟。模拟结果表明:在棉花生育期内,地下水位模拟结果和实测结果的一致性较好,该模型可有效地模拟预测水测坑控制排水条件下地下水位特性;控制排水措施能有效调控地下水位。
A leaching-pond experimental project is carried out in Jingzhou City, Hubei Province to research into the effect of controlled drainage on groundwater table. And DRAINMOD model is used to simulate the designed experiment schemes. The results show that the numerical results of the groundwater table from DRAINDOD model are quite similar to the practically measured results during cotton growth period. DRAINDOD model can effectively simulate and predict the character of water table under controlled drainage in leaching-pond experiment. Controlled drainage can effectively adjust underground water level.
