摘要
为揭示池河流域降水量时空分布特征,对明光站以上流域8个雨量站1970~2009年的逐月降水量资料进行处理分析,得出流域全年、汛期和非汛期的历年过程线和降水量空间分布图。结果表明:池河流域降水量年内分配不均匀,为典型的"复式峰"型,汛期降水量占全年的60%以上;全年和汛期降水量序列呈不显著的减少趋势,且有相似的涨-落变化过程;在空间上,全年和汛期降水量具有由东部山地丘陵区向西部岗地逐渐减少的分布特点。
In order to reveal the characteristics of precipitation time-spatial distribution of Chi river basin, the monthly precipitation data of 8 precipitation stations upstream Mingguang hydrological station are processed, and the annual, flood and dry season precipitation hydrographs and the rainfall spatial distribution maps are got. The results show that： the annual precipitation distribution nonuniformity in Chi river basin, and the curves mainly belong to double peak type, the flood season precipitation account for over 60% of the annual. The annual and flood season precipitation time series showed decreasing tendency, and had similar fluctuation process. In spatial terms, the annual and flood season precipitation of eastern hilly area are more than western downland.
