辽河保护区河道清障技术研究

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，但近年随着阻水障碍物等的违规发展，其行洪安全问题日益引起关注。通过对历年辽河保护区河道清障情况的分析，结合河障实地踏勘成果，确立了辽河保护区河道清障的范围与目标；同时研究了远近期辽河保护区河道清障技术，探讨了河道的清障效果；并针对研究过程中发现的问题，提出了一些建议。辽河保护区河道恢复工作的顺利实施是解决河道行洪安全问题的关键途径，可实现辽河保护区的防洪安全和生态安全双赢的效果。

Technologies of River Barrier Clearance in Liaohe Conservation Area

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.
