基于生物多样性保护的城市绿色廊道研究--以英国自然环境白皮书交通绿廊建设为例

Study on Urban Green Corridor Based on Biodiversity Protection:Taking the NEWP32 Transport Green Corridors in Britain as an Example

由于城市建设等人为因素干扰,自然生境遭受破碎化、岛屿化等破坏,城市生物多样性持续退化,其保护工作亟待全面展开。沿交通道路、水系等的绿色廊道能够加强自然生境的连接度,恢复和保护区域内的生物多样性,从而稳定城市生态结构。当前,正值国土空间规划体系重构时期,为了更好地构建城市绿色网络新格局,文章针对城市绿色廊道建设与生物多样性保护的问题,通过总结相关文献和报告,介绍英国自然环境白皮书交通绿廊建设的发展经验。研究梳理了英国自然环境白皮书交通绿廊建设的目标、方法和步骤,尤其是在其规划过程中建立的景观生态评价体系,以此来综合分析各地段的生态状况并辅助决策。上述分析可以使人们认识到城市绿色廊道建设对于生物多样性保护和生态系统稳定的重要性与必要性,并对国内地区的绿色廊道规划建设提供经验借鉴。

Due to the interference of urban construction and other human factors,the natural habitat has been destroyed by fragmentation and islanding,and the urban biodiversity continues to degrade,where the protection work urgently needs to be fully implemented.Green corridors along linear infrastructure such as traffic roads and water systems can strengthen the connectivity of natural habitats,stabilize the urban ecological structure,and restore and protect biodiversity in the area.At present,it is in the period of promoting territorial spatial planning.In order to build a better pattern of urban green network,this article summarizes relevant documents and reports,and introduces the development experience of the British Natural Environment White Paper on the construction of traffic corridors in response to the problems of urban green corridor construction and biodiversity conservation.The study combed the goals,methods,and steps of the British Natural Environment White Paper traffic corridor construction,especially the landscape ecological evaluation system established in the planning process,in order to comprehensively analyze the ecological conditions of each section and select planning strategies.The above analysis can make people realize the importance and necessity of the construction of urban green corridors for the protection of biodiversity,and obtain the experience of the British Natural Environment White Paper traffic corridor for the planning and construction of green corridors in domestic areas.
