摘要
土壤水分特征曲线是表征土壤中水的含量与势能之间的关系,是研究包气带土壤水分的保持和运移所用到的基本特性曲线。现通过试验,分析了不同条件下不同剖面层次的土壤水分特征曲线的差异,验证了基于不完全分形理论的土壤水分特征曲线模型,并对模型中的参数进行求解。
Soil moisture curve is elementary curve that shows the relation between potential energy and the content of water soil and analyses retaining and transporting in soil water belt. Through experiment, This paper analyses the discrepancy of the soil moisture feature curve of different levels with different planting conditions, and has verified the model of the soil moisture feature curve based on theory of incomplete fractal theory.
