摘要

神府-东胜矿区开发对入黄泥沙的影响是普遍关心的问题之一。该文利用矿区60年代以来的降水资料进行谐波分析，预测未来15a降水量的变化和年内变化。结果表明：未来降水量比多年平均值增加6%左右，且年际波动性增大，年内分布更加集中，洪水量和输沙量有增大的趋势。

Abstract

The influence of coal exploitation and construction of Shenfu-Dongsheng coal mining area on sediment transportation of the Yellow river has been paid more attentions. Using precipitation data since 1960's

spectrum analysis is conducted to forecast precipitation in the 15 coming years and its seasonal distribution. The result shows that annual rainfall in the 15 coming years will increase by about 6%

annual rainfall fluctuation will increase and rainfall concentration in a year tends to increase

which will make flood and sediment increased.
