摘要 在讨论土壤-植物系统中水流行为的基础上,分析了非线性电模拟模型的优越性,并借助于该模型定量地研究了土壤-玉米系统中各部分水流阻力、水容的大小及相对重要性,同时讨论了反映非线性模型的特征参数-时间"常数"的变性问题,丰富和完善了土壤-植物系统中水分运移的瞬态流理论。 Based on the development of non-linear model of water flow in the soil-plant system in this paper,the components of hydraulic resistances and capacitances were evalu- ated.Their relative importances were compared,and the time constant of unsteady water flow was researched.
