| 摘 要： | 本文采用黄河中游多沙粗沙区具有代表性的17个雨量站的近40年旬降水量资料,分析了其降水量变化的特点和分布规律。结果表明:多沙粗沙区降水量年内分布集中,季节差异大;区间降水分配不均匀,且可分为三种明显不同的类型。各区降水量近几年来都呈现出明显的减少趋势。

| Abstract: | The precipitation data,from 17 station in sandy area in the mid-Yellow River,of recent 40 years have been used to analyze variational character of the precipitation and its distributing rule.The results showed that the seasonal precipitation is obvious difference and asymmetry in different area.Three types can be concluded according to the precipitation in each area. In recent years,the precipitation in each area decreased abviously. |
