淇河及支流水生态保护修复工程案例分析

Case study on ecological protection and restoration project of Qi River and Branch River

本文构建了林州市淇河及支流水生态保护修复系统,该生态修复系统主要采用河流生态缓冲带、生态护坡、生态湿地、生境营造、水生植被恢复等修复技术措施。通过对效果分析可以看出,所采取的修复措施能够有效去除水体中的COD、氨氮、总磷等污染物,主要水质指标由原来的地表水Ⅲ类转变为地表水Ⅱ类,水生生物多样性明显增加,运行费用低,生态环境效果稳定,具有良好的应用前景及环境、社会效益。

In this paper,the ecological protection and restoration system of Qi River and Branch River in Linzhou City is constructed.The ecological restoration system mainly adopts river ecological buffer zone,ecological slope protection,ecological wetland,habitat construction,aquatic vegetation restoration and other restoration technical measures.Through the effect analysis,it can be seen that the remediation measures taken can effectively remove COD,ammonia nitrogen,total phosphorus and other pollutants in the water body,the main water quality index has changed from the original surface water class III to surface water class II,aquatic biodiversity has increased significantly,the operation cost is low,the ecological environment effect is stable,and has a good application prospect and environmental and social benefits.
