- 摘要:
- 本文在土壤-植物系统中水流过程物理分析的基础上,建立了该系统中水流电模拟最通用的非线性模式.用模拟实验的资料估算了模式中的参数,并预报了植物叶水势的动态变化过程.模拟结果与实验之间的比较令人满意.此外,本文还对土壤-植物系统中水流的电模拟理论和概念有所发展和完善.
- Abstract:
- Based on the physical analysis of water flow processes in soil-plant system,a universal model of cicruit analog for water flow in the system was de veloped in this paper.The parameters in the model were evaluated by use of two simulating experiments conducted in greenhouse and growth rome respectively.The leaf water potentials were predicted by the model and the results between simulation and experiment work are satisfacto ry.Moreover,some aspects of the theory and concept in circuit anolog for water flow in the system have been developed and deepened.
