计算机抽站法在青海巴州沟流域雨量站网密度分析中的应用

APPLICATION OF THE METHOD OF REDUCING RAIN-GAUGE STATIONS WITH COMPUTER TO ANALYSE THE RAIN-GAUGE NETWORK DENSITY IN BAZHOUGOU VALLEY OF QINGHAI PROVINCE

本文应用计算机随机抽站和组合抽站两种方法，对青海湟水支流巴州沟流域配套雨量站网按6、12、24小时三种时段、四种误差（5％、10％、15％、20％）分别进行计算后，确定了该流域的合理布站密度。

With the random and combination methods of reducing the rain-gauge stations,the pa-per analyses the rain-gauge network in Bazhougou valley,being the tributary of Huangshui river of Qinghai province,and determinates the reasonable rain-gauge network density. according to three periods of 6,12 and 24 hours and four errors of 5%、10%、15% and 20%.
