摘要
绿化隔离带概念已经有大约 10 0年的历史 ,特大城市周围建设绿化隔离带是国际上很多城市改善城市环境质量和防止城市蔓延的一种重要举措。虽然绿化隔离带规划思想在当时是进步的 ,但是它缺少同时代的绿色通道概念具有的生态和休闲等内在优势。本文主要以北京市绿化隔离带为例 ,从分析其规划思想和建设实施中存在的问题入手 ,详细阐述了北京市从绿化隔离带到绿色通道转化的必要性及重要意义 ,并提出具体实施策略。
There are about 100 years since the concept of Greenbelt arising. It is a great measure to improve the environmental quality and prevent city from sprawling by means of building greenbelt around metropolis.
