【摘要】 根据泾阳、淳化气象站1990～2010年气温、降水、蒸发、风资料和冶峪河淳化水文站1990～2010年洪水、径流、泥沙资料,结合历年统计值,从冶峪河流域概况、水系、气候、地质、降水、蒸发、洪水、径流、泥沙等方面论述了该流域的气象水文特征。冶峪河流域地处暖温带,属大陆性季风气候,四季冷热、干湿分明;洪水主要由暴雨形成,洪水汇流历时短,峰高量小,暴涨暴落,变化急骤,径流补给以雨水为主,具有明显的季节性特点,年内分配不均,年际变化大,河流含沙量和输沙量都较大。更多还原

【Abstract】 Based on the data of temperature, precipitation, evaporation, wind and flood, runoff and sediment of Jingyang and Chunhua meteorological stations from 1990 to 2010, combined with the statistical data over the years, the meteorological and hydrological characteristics of the Yeyu River Basin are discussed from the aspects of general situation, water system, climate, geology, precipitation,evaporation, flood, runoff and sediment. The Yeyu River Basin is located in the warm temperate zone and has a continental monsoon climate with distinct cold, hot, dry and wet seasons. Floods are mainly caused by rainstorms. Flood confluence lasts for a short time, peak height is small, ups and downs are sharp, and runoff recharge is mainly rainwater, which has obvious seasonal characteristics. The annual distribution is uneven, the annual variation is large, and the sediment content and sediment transport of rivers are large.更多还原
