| 摘 要： | 暴雨是诱发山洪的主要原因,雨量监测站网的布设至关重要。本文采用抽站法和流域水文模型法对江西遂川江流域雨量站网密度进行了分析研究,得出允许误差控制下的最少监测站数量。对比分析站网密度公式计算结果,大流域内的子流域区划对雨量站数量有很大影响。综合考虑流域特征、地形起伏及流域内人口密度、社会经济水平等因素修正的站网密度公式,为无资料地区山洪监测预警系统建设提供参考。

| Abstract: | Storm is the main cause of inducing flash floods,so that it is important to establish rainfall monitoring network.In this paper,the density of rainfall network in the Suichuanjiang River Basin of Jiangxi Province was analyzed using the method of extracting stations and the method of watershed model method,and the minimum number of monitoring stations was obtained under the control of allowable error.The comparative analysis of the results from network density formula shows that the sub-basin division in a l... |
