| 摘 要： | 利用近50 a的实测数据,分析了泾河流域的径流时空变化规律和主要驱动因子.研究表明:年降水量和径流深的空间分布均呈现从南到北的明显减少趋势,并在上游山区出现高值区.流域径流总量自20世纪60年代到21世纪初显著减少,由50.1 mm减到22.3 mm,但各区域的变化很不均匀,其中西部、西南和东南的子流域径流大量减少,可...

| Abstract: | The spatio-temporal variation of annual runoff in the Jinghe River Basin of Northwest China and its main driving forces were studied based on the meteorological and hydrological data over 50 years in this paper.It showed that the precipitation and runoff presented an obvious decreasing trend from south to north in the Jinghe River Basin,the high value areas of both precipitation and runoff existed in the upstream mountainous parts.While the averaged temperature in the basin increased significantly in last 5... |
