摘要
河滩地建设是实现河流生态系统修复目标的重要环节。通过分析探讨国内外河道河滩地实践案例,总结其优秀的生态设计思路,应用于具体设计中,并以重庆梁平区龙溪河礼让—仁贤镇河段河滩地生态工程为例,因地制宜,总结了河滩地生态设计的5大策略,详细论述了在示范段采用梯塘系统、河滩洼地系统两种模式对河滩地进行优化设计和实施,利用河滩地作为缓冲区拦截及净化地表径流中面源污染,提升了乡村河流景观品质,丰富了生物多样性。研究探索了一种能够集合河滩地滞水、自然生境和景观需求等诸多功能于一体的河滩地建设形式。
The construction of flood land is an important link in achieving the goals of river ecosystem restoration.This paper analyzes,discusses and summarizes the practical cases of river beach land at home and abroad,draws on its excellent ecological design techniques and ideas,and applies them to specifi c designs.Taking the ecological engineering of fl ood land at the reach of Lirang Renxian Town,Longxi River,Liangping District,Chongqing as an example,taking local conditions into consideration,this paper summarizes several strategies for the ecological design of fl ood land,and discusses in detail the two models of ladder pond system and riverbank depression system in the demonstration section,optimizing the design and implementation of fl ood land,using fl ood land as a buffer zone to intercept and purify non-point source pollution in surface runoff,has improved the quality of rural river landscape and enriched biodiversity.Explored a construction form of fl ood land that can integrate various functions such as stag-nant water,natural habitat,and landscape needs.
