| 摘 要： | 对重庆缙云山森林生态效益监测站竹林监测区毛竹于流进行了观测研究。结果表明：毛竹干流量y(mm)在降雨量大于0．3mm时即可形成,与降雨量x(mm)的关系为：y=3e^=-6x^4 0．0005x^3-0．026x^2 0．5589x-1．463(R^2=0．9335);与出竹年度的关系为weibull函数关系。于流量、于流强度、于流率、于流持续时间、于流开始时间与降雨性质和毛竹植株特性等有关,影响干流的最主要因子是降雨量．植株的胸径、枝下高、株高对于流影响程度几乎相等。于流过程与LCR电路暂态过程相似。

| Abstract: | The stem flow of Phyllostachys can be observed when the rainfall is more than 0.3mm at the monitoring station of forest eco-benefit at Jinyun mountain forest in Chongqing. The relationship between stem flow y (mm) and rainfall x (mm) is y=-3e~(-6)x~4+0.000 5x~3-0.026x~2+0.558 9x-1.463(R~2=0.9335), and for the born year is Weibu. The amount, intensity, rate, duration and start time of a Phyllostachys stem flow are decided with its propertities and the character of rainfall. The main effective factor is rainfall, and the impact of DBH, height under branch, and height on stem flow is almost the same. The process of stem flow is similar to the LCR electric circuit transient state. |
