基流分割的简便计算法

鉴于基流分割计算费时，效率低。本文提出一种基流分割的简便计算方法。该法是将实测径流过程点绘在半对数纸上，以直线连接过程线的相应起涨点和拐点，然后建立该直线的数学模型，用积分法求直线以下部分的基流量。与一般列表法相比，其具有速度快、精度高等特点。

A Simple and Convenient Calculation Method on Base Flow Separation

Since the calculation of base flow separation is time-consuming and inefficient, the writers have suggested a simple and convenient method that is to draw the actual measured process of runoff on half logarithm paper, then take the straight line connect with the response beginning and inflection points of process line, then establish the mathematic model of the straight line, calculating the base flow amount under the straight line with integral method. This method is speedy and high precision as compared with other common tabulation methods.
