| 摘 要： | 以以色列西南部Berry的原状土壤为例,采用滴水穿透时间法测定土壤斥水性随土壤由湿到干的变化情况,并对此关系建立正态、指数正态、对数正态3种数学模型,在对各模型进行综合指标评定后得出,指数正态模型为最佳数学模型。经实测数据进行验证和误差分析,预测结果很好。为进一步研究土壤斥水性和进行土壤改良提供理论依据。

| Abstract: | The present research work studied the relationship between the soil water repellency and water content by measuring Water Drop Penetrate Time(WDPT) using a sand soil collected from the Kibbutz Berry,Israel.A normal distribution was found for expressing the relationship between the water repellency and water content statistically.Three mathematic models,namely normal,exponential and lognormal distributions were used for fitting the models by regression analyses.The exponential distribution was found to be th... |
