绿量的城市热环境效应研究现状与展望

绿量对城市热环境的调控功能已成为目前研究热点。本文从绿量的概念与发展、绿量与城市热环境的调查方法、绿量与城市热环境的关联性以及其在城市规划方面的启示4方面进行论述,总结国内外研究进展,提出了未来该领域的4个发展方向,包括三维绿量调查方法的改善、城市热环境的监测与预测、城市绿量三维空间格局指标体系的构建以及关联绿量与城市热环境研究的三维空间格局分析方法的创建。本文为研究绿量调控城市热环境提供了一种三维空间分析的视角,以期更深入地探索城市绿量的三维空间格局、平衡城市热环境的适宜性和多方面生态效益,为城市绿色空间规划与设计提供科学依据,也为人类适应气候变化并科学调控城市热环境提供理论支持。

A review of research on the urban thermal environment effects of green quantity

The regulative function of green quantity in urban thermal environment is an important topic in urban studies. Here, we reviewed the concepts and developments of green quantity, the measurements of green quantity and urban thermal environment, the relevance between green quantity and urban thermal environment, and its implications for urban planning. After summarizing domestic and international research processes, we put forward four prospective directions: 1) improving the methods for three-dimensional investigation of green quantity, 2) developing means for urban thermal environment monitoring and forecasting, 3) establishing an index system for three-dimensional pattern of urban green quantity, and 4) creating three-dimensional analytical methods to quantify the relationship between green quantity and urban thermal environment. It was expected to provide a three-dimensional spatial perspective for exploring the relevance between green quantity and urban thermal environment. It was proposed to deeply examine three-dimensional patterns of urban green quantity, in order to balance urban thermal environment and multiple ecological benefits, and to provide scientific basis for urban green space planning and design, as well as to form theoretical supports for adaptation to climate change and regulation of urban thermal environments.
