摘要
辽河历年来洪涝灾害频繁,虽然过去开展过多次河道恢复工作,但近年随着违规阻水障碍物增多,其行洪安全问题日益突出。研究分析了历年辽河保护区河道清障情况,基于河障实地踏勘成果,确立了辽河保护区河道清障的范围与目标;研究了辽河保护区河道清障技术,探讨了清障效果;针对研究过程中发现的问题,提出了措施建议。辽河保护区河道恢复是解决河道行洪安全问题的主要途径之一,有助于实现辽河保护区的防洪安全和生态安全的双赢。
Floods frequently occurred in Liaohe River in the the years. Although the work of river barrier clearance had been performed for several times, the illegal water-blocking barriers still increased, flood risks and safety in Liaohe River have attracted more and more attention. The history of river barrier clearance in Liaohe Conservation Area was analyzed; and the scope and objectives of river barrier clearance was established, based on the reconnaissance results of Liaohe River course. Also, the barriers clearance technology was studied in Liaohe River course, and the effects were discussed. Measures for implementing on the river barrier clearance were proposed, with respect to the problems found in the research. River course recovery is one of the main approaches to solve the flood safety problems, which help to achieve the win-win of flood safety and ecological security in Liaohe Conservation Area.
