南盘江流域水文特性分析

Analysis of Hydrology Characteristics in Nanpanjiang Basin

南盘江为珠江流域发源的主干流 ,是我国西南云贵高原地区的一条重要河流 ,其降水、径流、泥沙、蒸发等水文特性在南方河流中具有一定的典型性。通过对水文特性的分析 ,揭示其内在规律和相互联系 ,以提高水文预报能力 ,更好地为该流域上的天生桥水电站的水库调度和防洪度汛服务。

As a main stream sourced from Zhujiang basin, Nanpanjing is an important river of Yunnan Guizhou plateau in south western part of China, having typical characteristics in precipitation, runoff, sediment and evaporation of rivers in south China. The analysis of its hydrological characteristics reveals its inherent laws and interconnections,and improves accuracy in hydrological forecast,providing a better service in the reservoir dispatch and flood prevention for Tianshengqiao Hydropower station, which locates in this river basin.
