摘要
本文利用负轮理论分析了陕西渭河流域干流及三条支流六个水文站水文干旱现象。渭河流域水文干旱是一仲常见的水文事件,多以连续的形式出现。景大缺水量渭河占多年平均径流的60%以上,泾河、洛河、石头河40—50%左右。年内月水文干旱的分布具有周期性的规律。
In this paper, the negative runs theory has utilized to analysis the hydrologic drought phenomenon of the six hydrologic stations in the main stream and three tributaries of the weihe River basin. The hydrologic drought is a commnly hydrologic event, and usually occurenceas continous drought. The maximum water edficit is about 40%～60% of the annual normal flow, The annual distribution of monthly hydrologilc drought has showed periodicity.
