摘要
通过对14个代表站降水量资料的分析,得出了祖厉河流域降水量的变化特征、时空分布规律及变化趋势。祖厉河流域降水量年内分配不均,年际变化大,降水量随时间递减的趋势显著。
Through analyzing the practical annual precipitation data of 14 representative hydrological station, the change character, the spatial distribution and the change trend of annual precipitation were obtained. The annual precipitation distribution was asymmetry in Zuli river drainage basin. The decade variation of annual precipitation change obviously and the annual precipitation decreasing trend was derived.
