本文以新安江模型为研究手段,用我国广东省马屋流域为实例,揭示了水源比例对于汇流的非线性影响。由分析成果可知,若將水源划分为地面、壤中、地下三种,则各次洪水的水源比例是不同的,但划分水源的参数与汇流参数名次洪水都相同,汇流系统基本上是线性的;若將水源划分为地面和地下两种,则划分水源的参数与汇流参数极不稳定,汇流系统为非线性的。
In this paper, the Xin’anjiang model is taken as a research method. Taking the Mawu basin in Guangdong Province of China as an example, the nonlinear effect of water source ratio on confluence is revealed. According to the results of the analysis, if the water source is divided into three types of ground, soil and underground, the proportions of water sources of each flood are different, but the parameters of dividing the water source are the same as the flood of the confluence parameters, and the convergence system is basically linear If the water source is divided into two kinds of ground and underground, the parameters of the water source division and the confluence parameters are extremely unstable, and the confluence system is non-linear.
