随着城市化水平的提高以及城市空间密度不断加大,城市风环境问题成为了多学科研究关注的热点,风环境对景观环境设计、空气质量改善、开放空间热舒适度感知均具有重要的作用。从风环境研究的技术演进和其评价体系建构两个角度来分别对国内外城市风环境研究进行了梳理与总结,将其技术演进分为实地测量法研究、物理模拟法研究和计算机数值模拟法研究三个阶段进行详细分析,对现有的城市风环境评价体系特征进行了整合,相关技术方法能对城市规划起到积极的补充,具有明显的实践效果。
With the increasing urbanization and density of urban space, urban wind environment became one of the focuses of multidisciplinary research. The wind environment plays an important role on all the diffusion of air pollutants, heat island effect, and thermal comfort perception of open space. This article reviews the oversea studies on technical evolution and evaluation system construction of urban wind environment. Analyzes the evolution of its technology research in field measurement research, physical simulation research, and computer numerical simulation research. Then integrates the existing urban wind environment evaluation system features.
