基于分形法的百色水库汛期分期研究

Divide flood season by fractal method for Baise Reservoir

水库分期汛限水位动态控制是洪水资源化利用的有效途径之一,为了提高百色水库对洪水的调节作用和洪水资源化利用效益,采用基于日最大值取样的分形法对百色水库进行汛期分期,最后得出百色水库汛期分期为:汛前期为5月1日~6月20日,主汛期为6月21日~8月20日,汛末期为8月21日~10月31日。

Dynamic control of flood limit water level of reservoir is one of the effective ways to utilize flood resourc- es. In order to improve the flood control capability of Baise Reservoir and increase the benefits of flood resource uti- lization, the flood season is divided into three periods by fractal method based on daily maximum sample, consisting of early flood period from May 1 to June 20, main flood period from June 21 to August 20 and late flood period of Au- gust 21 to October 31.
