摘要
目前,在水文计算中,多用泰森多边形法计算流域平均雨量,该法的计算公式是采用面积加权法。但该公式中对单站控制面积的计算方法不合理,与实际降雨情况不符。由于未找到比泰森更合适的计算方法,致使此方法一直延用下来。针对上述情况,本文对单站控制面积提出新的计算方法,对泰森多边形的计算公式进行修正,使泰森多边形法更加完善。
Nowadays Tayson's polygon method has beew mostly used to calculate the average rainfall of drainage area. This method is a weighted averages method. But in this formula the ealeulating method of unit controlled area is unreasonable, which does not conform to the actual rainfall situation. Since no better method has been found yet, this method has long been used contin-uously.In view of this, this artile is Putting forward a new method to amend Tayson's and make it more perfect
