| 摘 要： | 本文以1962-1989年水文资料和雨量站资料为基础,分析了藉河流域水沙的季节及年际变化规律,并且对降雨与人类活动导致的年径流泥沙变化影响进行了估算.研究结果表明,藉河流域水沙年内分配极不均匀,7-10月径流量占全年的61.6%,6-9月泥沙量占全年的87.9%;水沙年际变化剧烈,输沙量和径流量的变差系数分别为0.72...

| Abstract: | Based on the hydrologic and area precipitation data during the period of 1962 to 1989,the seasonal and annual changes of runoff and sediment were analyzed,and the influence of precipitation and human activi-ties on the runoff and sediment were estimated.The results showed that the seasonal distribution of runoff and sediment yield was quite uneven.The runoff between July and October accounted for 61.6 percents of the year,and sediment yield from June to September made up 87.9% of the year.The annual distrib... |
