    摘要:

    選用以色列3類不同質(zhì)地的10種不同斥水性的土壤為研究對象，采用滴水穿透時間法測定土壤斥水性對含水率的響應關系，得到了不同土壤斥水持續(xù)時間隨含水率變化的規(guī)律，通過Gaussian模型、Lorentzian模型和Lognormal模型對這種規(guī)律進行回歸分析，最終得出了土壤斥水持續(xù)時間隨含水率的變化規(guī)律符合Lorentzian模型。由此響應模型，就可以根據(jù)某種土壤部分斥水性對含水率響應的實測數(shù)據(jù)，計算出土壤斥水性的峰值含水率、峰值斥水性以及臨界含水率，為不同土壤斥水性進行對比和土壤改良提供理論依據(jù)。

    Abstract:

    The relationships between the soil water repellency and soil moisture were studied by measuring WDPT using 10 different water repellent soils collected from Israel. A single peak curve correlation of the relationships between the WDPT and soil moisture was obtained after analysis. Three mathematic models, namely Gaussian, Lorentzian and Lognormal distributions were used for fitting the models by regression analysis, and the Lorentzian distribution was found to be the best model for the practical use. The peak soil moisture, the peak WDPT and the critical soil moisture can be computed by the model of part measured WDPT and soil moisture. It can provide the theory for amelioration of soil and compare of the different repellent soils.
