摘　　要：基于黄河下游河流影响带3条监测剖面的监测数据,结合环境地质调查及两个时段的环境地质卫星遥感图像,分析了小浪底水库运行后黄河下游环境的整体变化趋势。结果表明:小浪底水库运行后,避免了下游河道断流,黄河径流量趋于稳定,下游灌区得以安全运行和发展,各灌区实灌面积得到稳定和扩大,下游地下水调蓄功能增强,傍河水源地主要补给源稳定、运行安全性提高;同时使河道带土地沙化加重、湿地面积减小、水源地地下水位埋深增加。The paper analyzes the whole trend of variation of the environment of the lower Yellow River after the operation of the Xiaolangdi Reservoir based on the monitoring data of three monitored profiles of the influence zone on the lower Yellow River and combining with environmental and geological survey and the remote sensing images of environmental and geological satellite of two periods of time.The outcomes show that a) after the operation of the Xiaolangdi Reservoir,there is no zero flow happened in the lower channel,the river runoff is heading for stability,the irrigation area on the lower reaches can be operated and developed safely,the actual irrigated area of each irrigation area has been stabilized and expanded,the storage function of groundwater of the down stream has been increased and the main source of alimentation of headwater region on the side of river is stable and operational security increased;b) in the meanwhile,the soil desertification of the channel is getting worse,the area of wetland reduced and the depth of groundwater level of the headwater region increased.
