| 摘 要： | 利用SWAP(Soil-Water-Atmosphere-Plant)模型对河套灌区的永联试验区进行了排水工程管理的数值模拟研究,分析了排水沟的间距和深度对田间水均衡要素的影响。结果显示,现有排水沟深度下的排水沟间距调整对区域排水和潜水埋深的影响不明显,但当排水沟深度增加时,排水沟排水量和控制区域的潜水埋深发生显著变化。根据模拟结果,认为永联试验区的排水沟间距取500 m,深度取2.5 m较为适宜。

| Abstract: | This paper analyzes the influence of depth and spacing of drainage ditch on water balance of farmland based on SWAP(Soil-Water-Atmosphere-Plant).The experiment site is a sublaterals area in Hetao irrigation district.The result shows that for the present depth of drainage ditch,narrowing the spacing of the drainage ditch has no evident influence on water balance of farmland;but when the spacing is fixed,the drainage water and underground water depth change evidently with the increase of depth of drainage dit... |
