| 摘 要： | 基于湖北四湖流域大量调查观测资料分析了易涝易渍农田土壤水分变化规律。结果表明：不同层次上土壤水分年平均值差异很小，在不同水文年以及同年内的不同季节则差异较大；当地下水埋深≤1m时，对耕层土壤水分影响明显；在一定条件下，土壤水分与地下水埋深、时段内累计雨量和累计蒸发量之间有显著的相关关系。

| Abstract: | Soil moisture in a field prone to surface and subsurface waterlogging was studied based upon a lot of information obtained by investigation and observation in the four-lake watershed in Hubei Province.Analysis results showed that yearly average moisture of soil located in different layers is quite close and merely a minor difference.However a great difference of it existed in different years and seasons;topsoil moisture is obviously affected by groundwater when groundwater depth below the land surface is le... |
