摘　　要：雨量站网是水文站网整体功能中极其重要的一个组成部分,雨量资料的准确性和代表性,将直接影响洪水预报的精度,科学地规划和优化雨量站网,使雨量资料最大程度地反映流域的实际降雨情况,可以大大提高洪水预报系统的精度。根据水文技术发展的现状,采用抽站法,基于GIS技术,加入地形、气象等下垫面因素综合考虑,对梅雨地区雨量站网进行优化研究。Rainfall station network is one of the extremely important components for hydrological station network, and the precision of flood forecast is directly affected by the accuracy and representative of rain-gauge data. Thus, in order to better improve the precision of flood forecast, it is vital to scientifically plan and optimize the rainfall station network to make rain-gauge data reflects the actual rainfall in the region as exactly as possible. Based on the current development of hydrological technology, this paper adopted reducing rain-gauge station method and GIS technology, and took underlying surface factors like landform, weather and stationing into account, to optimize a rain-gauge network of the experimental region in Jiangxi Province.
