让自然做功的河道生态修复——以呼和浩特大黑河城区段景观概念规划为例

River Eco-Restoration with Nature Acting——Huhhot Black River Eco-landscape Conceptual Planning

河道是生态敏感、脆弱而又具有显著景观价值的重要生态廊道。只有在规划设计实践中发现和顺应河流的自然形态和自然演变规律,在尊重和保护的基础上进行生态修复,才能真正走向人地和谐。本文以呼和浩特大黑河城区段为研究对象,分别在时间和空间维度上分析总结了大黑河河道形态演变的主要规律和自然诱因,并在此基础上提出了引导洪水对河道形态进行自我修复的生态修复方法。在整体生态系统修复策略上,提出了建立"四维一体"的生态系统修复模型。从林、堤、滩、水4个方面分别探讨了生态景观设计的过程,突出了河道生态功能和景观特色的结合。

Rivers are usually sensitive, fragile yet highly valuable ecological corridors. The harmonious balance between city and natural system will only be achieved through ecological restoration and preservation by following and adapting to the natural law of river in our planning and design. An ecological river restoration method adopting river self-recovery by flooding is discussed here, taking the research and study of Hohhot Black River （Dahei He） urban section in time and space dimensions. Based on this ecological system restoration strategy that integrates ecological function and landscape process, a four-dimensional restoration model is established to describe the ecological landscape process intervened by both nature and human, focusing on woods, levee, river plain and water factors.
