不同土层土壤水分特征曲线的空间变异及其影响因素（Spatial Variability of Soil Water Retention Curve in Different Soil Layers and Its Affecting Factors）
土壤水分特征曲线 空间变异 多重分形
2010/1/28
利用多重分形和联合多重分形方法，对陕西杨凌地区0～20cm和20～40cm土层van Genuchten模型参数的空间变异性及其影响因素进行了研究。结果表明：0～20cm和20～40cm土层参数α都具有明显的多重分形特征，空间变异性较强，且分别是由低值和高值分布引起的；参数n和θs的多重分形特征不明显，空间变异性较弱。0～20cm和20～40cm土层van Genuchten模型参数与土壤物理特性...
