摘要: 以红松代表针叶树,栎树代表阔叶树,通过模拟实验研究树干径流过程,根据实验结果从机理上构造了模型。树干径流模型为一个方程组用“辗转迭代法”求出了数值解。该方程组基本上揭示了树干径流的规律,从实验与模拟结果对比分析中得到了佐证。

Abstract: With Korean pine as the example of coniferous tree and Oak as the example of deciduous tree,stemflow hydrograph was studied by the method of simulation experiment. According to experimental results,a model of stemflow was constructed. The equation set was solved numerically with iteiative method. The equation set shows the law of stemflow,it was proven by the comparative analysis of stemflow experiment and relevant simulation.
