基于多目标协同的城市生态修复分区技术体系研究

Study on the Technical System of Urban Ecological Restoration Zoning Based on Multi-objective Collaboration

城市属于人口密集、社会资源高度集聚的特殊空间类型,其生态系统脆弱。城市生态修复的目的在于恢复社会-经济-自然复合生态系统的合理结构、高效功能和协调关系,然而目前仍然缺乏从“生态保护到修复后再利用”的全流程多目标分区技术体系研究。基于生态保护、地质安全、环境质量、生态景观和生态功能提升等多目标及协同关系构建,提出了涵盖优先保护修复、地质灾害防治、污染防治、植被修复和修复后再利用等5方面的城市生态修复分区技术体系,深入阐述了重点环节区划内容与策略,并对未来发展趋势进行了展望,以期提升城市生态修复精细化、可持续发展水平。

Being a special spatial type with dense population and highly concentrated social resources, Urban has a fragile ecosystem. Urban ecological restoration is aimed to restore the appropriate structure, efficient function and harmonious relationship of the society-economic-natural complex ecosystem. However, there is still lacking of research on the whole process multi-objective zoning technology system of "ecological protection to reuse after restoration". Based on the multi-objective synergistic relationship construction of ecological protection, geological safety, environmental quality, ecological landscape, ecological function development, a technical system of urban ecological restoration zoning is proposed, which covers 5 aspects of preferential protection and restoration, geological disaster prevention and control, pollution prevention and control, vegetation restoration, and reutilization. The zoning contents and strategies of key links is elaborated and the future trend is forecasted toimprove refined and sustainable development of urban ecological restoration.
