摘要
随着城镇化的发展,一些城镇河湖生态系统与生态景观被破坏,需要通过多种措施恢复城镇河湖生态,为此,以保定市为例,开展了兼具景观功能的城镇河湖生态治理的研究。一方面,在河道堤岸建立生态防护工程,选择堤岸生态植被和水生植被,在布局形式下构建生态坡面,平衡堤岸稳定性与生态功能性;另一方面,建设水生态系统修复设施,划分自然湿地与人工湿地分布区域,设计与规划不同类型湿地的植被景观,恢复城镇河湖的生态效应。经过一系列治理措施提出与应用,在城镇河湖生态治理中以生态保护工程修复河道堤岸,人工湿地景观修复水体富营养化,既具有观赏价值又具有保护意义,可以实现城镇河湖生态的和谐发展。
With the development of urbanization,some urban river and lake ecosystems and ecological landscapes have been destroyed,and various measures need to be taken to restore urban river and lake ecology.Therefore,taking Baoding City as an example,research on urban river and lake ecological governance with both landscape functions has been carried out.On the one hand,establishing ecological protection projects on river embankments,selecting ecological and aquatic vegetation on the embankments,and constructing ecological slopes in a layout form to balance the stability and ecological functionality of the embankments;on the other hand,building water ecosystem restoration facilities,dividing the distribution areas of natural wetlands and artificial wetlands,designing and planning vegetation landscapes for different types of wetlands,and restoring the ecological effects of urban rivers and lakes.After a series of governance measures have been proposed and applied,ecological protection projects have been used to repair river embankments and artificial wetland landscapes to restore water eutrophication in urban river and lake ecological governance.This has both ornamental value and protective significance,and can achieve harmonious development of urban river and lake ecology.
