摘要
灰色基础设施是导致完整生态循环系统被割裂进而恶化的根源,使绿色基础设施逐步修正和取代灰色基础设施是本文讨论的重点。以全球现有的三大绿色基础设施体系——美国、西欧和加拿大体系为例,通过概念、关键节点、典型案例等分析其异同,梳理绿色基础设施和灰色基础设施之间的衔接关系,以期对我国目前绿色基础设施发展有所借鉴。
The gray infrastructure is the root of the fragmentation and deterioration of the ecological cycle system. This paper focus to use the green infrastructure to gradually modify and replace the gray infrastructure. Through the analysis of the three major existing green infrastructure systems in the world, the United States system, the Western European system and the Canadian system. The similarities and differences between the three systems are analyzed and compared through historical, conceptual and typical cases, and the connection between the two facilities in the three systems is summed up. Then, combined with the current development of our country, it puts forward the direction for China.
