小流域雨量站网密度分析

Analysis on Precipitation Station Network Density of Small Watershed

确定雨量站网密度是水文站网规划中的一个重要问题。本文通过分析暴雨的空间分布特性，提出应用锥体梯度法估算雨量站网密度。该法简单，适用于雨量站稀少地区的雨量站网规划。

Determination of precipitation station is an important problem for the hydrological network design.Through analyzing the spatial distribution characteristcs of storms,this paper introduced the cone gradient method that is used to estimating precipitation station density.The method is straightforward,it is applicable to design precipitation station for those regions where precipitation station is spare.
