摘 要:选择位于黄河下游游荡型河段的花园口—高村河段作为研究对象,研究河防工程建设对河道湿地演变的影响。结果表明:其一,1980—2000年,黄河下游河道湿地规模经历了明显的减少过程,2015—2017年,河道湿地面积基本趋于稳定,变化幅度在1%以内;其二,控导工程对河道湿地有一定的影响,而大堤及险工对河道湿地影响较小;其三,河段相同时段控导工程建设规模、强度与河道湿地规模的变化之间无明显相关关系,控导工程建设不是造成河段河道湿地面积减少的主要因素;其四,控导工程对河道湿地的影响程度相对有限,在影响河道湿地演变的多种因素中,黄河水资源的支撑是决定性因素。The section from Huayuankou to Gaocun of wandering channel in the lower Yellow River was selected as the research section to study the influence of flood prevention works on the evolution of river wetlands in this paper.The results show:Firstly,during 1980—2000 the scale of river wetlands in the lower reaches of the Yellow River experienced a significant decline,during 2015—2017,the wetland area of river channels tended to be stable,with a change range of less than 1%.Secondly,the control works have some influences on the river wetlands,but levee construction and vulnerable spots have little influence on the channel wetlands in the lower reaches of the Yellow River.Thirdly,by comparing the scale and progress of the control works construction with the change of the scale of the river wetlands in the same period,there is no obvious correlation between the two,which indicates that the control works construction is not the main factor causing the decrease of the area of the river wetlands.Finally,it indicates that the influences of the control works on the river wetlands are relatively limited.Among the factors affecting the evolution of river wetlands,the support of water resources of the Yellow River is the decisive one.
