摘　　要：引黄必引沙,淤沉于黄河下游引黄灌区沉沙池、渠道等部位的大量泥沙造成的风沙运动使灌区周边生态环境持续恶化,对人民群众生产生活和社会经济的可持续发展构成极大威胁。本文依据风沙运动基本原理,深入分析了引黄灌区风沙的来源与分布、风沙颗粒组成特征,在此基础上,从风沙起动、风沙推移质运动、风沙悬移质运动三个方面对灌区风沙危害的方式与程度进行了科学的分析与评价,提出了灌区风沙危害的防治措施,试图为科学治理引黄灌区风沙危害提供技术支撑。Water diversion from the Yellow River has brought benefit to economy development in the Lower Yellow River. However, water diversion has caused a great deal of sediment deposited in settling tanks and channels, which brings a severe problem of wind-driven sediment. The wind-driven sediment deteriorates not only the environment around irrigation areas, but also threatens the production, people＇s life and economy development. The movement characteristics of wind-driven sediment including the source, distribution and size gradation were analyzed. On this basis, the fashion and degree of harm of wind-driven sediment were then assessed. Finally measures to prevent the harm of wind-driven sediment is proposed, which provides a technical support for the management of sediment in the irrigation areas of the Lower Yellow River.
