| 摘 要： | 调查了中山大学珠海校区滨海小流域内的土壤质地情况,着重分析了其中一个径流试验场A中的土壤颗粒组成;根据实测土壤含水量、土壤吸力数据,用Gauss曲线拟合了吸水过程的土壤水分特征曲线,并编制了计算一维非饱和土壤水运动的计算机程序,模拟分析了径流试验场A在一次降雨入渗过程中、土壤含水量、土壤基质势的变化,获得了不同深度处的土壤吸水过程的水分特征曲线。

| Abstract: | We performed an investigation on soil texture in the small coastal watershed in Zhuhai campus of Sun Yat-sen University in the delta area of the Pearl River and analyzed the soil particle composition of runoff experimental plot A particularly.According to the measured soil water content and soil suction data,the soil moisture characteristic curve in soil absorption process is fitted with Gauss curve.A computer program for calculating one-dimensional movement of unsaturated soil moisture is developed,and the... |
