遂川江流域雨量站网密度分析研究

Study on Appropriate Precipitation Station Density of Suichuan River Basin

摘要: 确定雨量站网密度是水文规划的重要问题之一，也对开展水资源评价和水文预报至关重要。本文采用抽站法、江西雨量站网密度公式，对遂川江夏溪站流域的雨量站网密度进行研究，揭示了影响面雨量计算精度的主要因素，确定了给定精度要求下区域的合理雨量站布站的密度，为江西省遂川江流域及其他类似地区的雨量站网布设提供参考。

Abstract: Study on appropriate precipitation station density is one of the important problems in hydrological planning, hydrological forecasting and water resource assessment. In this paper, the station sampling method and the network density empirical formula of Jiangxi Precipitation Station are applied to inves-tigate the precipitation density of Suichuan River basin. As a result, the main factors influencing the accuracy of areal precipitation calculation are revealed, and the appropriate density of stations under the requirement of the given accuracy is determined. This provides a reference for the arrangement of precipitation stations network in the Suichuan River basin and other similar areas.
