[Planning approach of urban blue-green space based on local climate optimization: A review]
Abstract
Local climatic problems are widespread in cities under high-density and high-intensity construction mode in China, including heat island effect, poor ventilation, and frequent haze wea-ther. Urban blue-green space is vital for mitigating wind and heat, and for improving air quality, and therefore has become a hotspot of urban planning and design research dealing with climatic problems. Here, we reviewed the climate effects of urban blue-green space. In particular, we summarized the research progress of planning approaches to cool island landscape features optimization, cooling island configuration, ventilation corridor network connection and ventilation corridor interface control based on the levels of planning layout and network construction. We proposed a basic framework of urban blue-green space planning optimizing local climate by combining intelligent simulation platform, evaluation index system, planning and design guide, and guarantee mechanism for implement, aiming to provide key evidence for urban climate adaption and design.
在高密度、高强度的城市建设模式下,我国大中城市内部均面临着热岛效应加剧、通风能力下降、灰霾天气频发等局地气候环境问题。城市蓝绿空间作为调控城市风热环境、改善大气环境质量的关键要素,已成为城市空间规划设计领域应对局地气候问题的重要研究对象。本文通过对国内外城市蓝绿空间局地气候效应研究文献资料的回顾,从城市蓝绿空间规划布局、网络构建两个层面,梳理了冷岛景观特征优化、冷岛空间镶嵌布局、通风廊道网络连通、通风廊道界面管控的规划学途径研究进展,并总结了相关研究的主要成果及存在的主要问题,提出从智能仿真平台、评估指标体系、规划设计指南、实施保障机制4方面建立城市蓝绿空间规划应对局地气候问题的研究框架,以期为城市气候适应性规划理论创新提供有益启示。.
