摘要:
目前,黄河中游地区流域水沙变化的研究主要以水文法和水保法分析为主。由于黄河中游具有明显的自然地带性分布特征,流域系统的水沙过程受到环境要素的综合影响。根据黄河中游河口镇至龙门区间已控一级支流的测站资料,采用地理环境要素法分析水沙变异及成因。研究表明,河龙区间流域径流量和输沙量与地理环境因子的影响密切相关。20世纪70年代以来,降雨减水减沙作用不断减小,随着水土保持措施的提高,人类活动减水减沙所占比重不断增大。70年代与80年代气候波动和人类活动影响的平均减水减沙作用分别为53.4%、28.6%和46.6%
Abstract:
River sediment yield is the reaction of various natural factors and human action factor comprehensive role in basin, wash with sedimentation of river course to change, is related closely.Since 1970’s, the Yellow River mainstream discharge and sediment yield load to occurred variation, which discharge of water and sediment yield load decrease apparently, the new condition of the river course of lower reaches occurs dwindlingly and break to flow.The cause of runoff and sediment yield process variation is studied according to used analysis method of the geography environmental factor and data from the Hekou town to Longmen area of the middle reaches of the Yellow River.The result shows that runoff and sediment yield load of basins from the Hekou town to Longmen area of the middle reaches of the Yellow River is related closely with geography environmental factor, the climate fluctuation with human activities influence reduce runoff and sediment in average to 53.4%, 28.6% and 46.6% and 71.4% respectively from 1970’s to 1980’s .
