随着引黄灌溉事业的发展,大型灌区续建配套和节水改造项目相继启动,泥沙问题无论在水资源配置还是在环境保护上都成为不可忽视的一个重要因素。其中沉沙池及渠道清淤泥沙的处理是目前制约引黄灌溉发展的主要因素之一。以位山灌区为例,分析了灌区泥沙池区存在的问题,针对存在的问题从生态建设角度提出灌区沉沙区水土流失防治新模式,对促进引黄灌区沉沙池区的水土流失治理具有重要意义。
With the development of irrigation projects in the Yellow River Diversion Project, large-scale irrigation districts continued construction and water-saving reconstruction projects have been started one after another. Sediment problem has become an important factor that can not be ignored in terms of water resources allocation and environmental protection. Among them, settling sedimentation tank and channel sediment disposal are one of the main factors restricting the development of irrigation to the Yellow River. Taking Weishan Irrigation District as an example, this paper analyzes the existing problems in the sediment basin area of the Irrigation District and proposes a new prevention and control model of soil and water loss in the sediment-laden area of the Irrigation District in view of the existing problems in view of ecological problems. It is of great significance.
