摘要
城市风环境对城市大气的自净能力和城市居民的身心健康有着至关重要的作用。目前对城市规划区风环境的忽视,导致为城市提供冷气流及新鲜空气的补偿空间利用不足。GI是城市的生命支撑系统,将补偿空间运用于GI斑块识别中,对整个城市风环境及GI网络优化意义巨大,但现有GI研究中风环境要素的考虑不足。本文提出了GI斑块识别的新方法,使其更具现实意义,以适应当今城市的快速发展,为城市风环境的改善及空气质量的提升提出了可操作的具体措施,推动了城市生态环境的改善与生活品质的提高,对城市的可持续发展意义重大。
Urban wind environment have a vital importance to the self purification ability of city atmosphere and the physical and mental health of urban residents.At present,the neglect of the wind environment in urban planning area lead to insufficient use of compensation space that provide air flow and fresh air to city.GI is the city's life support system.The compensation space is applied to the identification of GI patches,which has great significance to the whole urban wind environment and GI network optimization,but the existing GI research is insufficient to consider the factors of stroke environment.In this paper,a new method of GI plaque identification is proposed,which makes it more practical to adapt to the rapid development of the city,and puts forward operable measures to improve the wind environment in the city and the improvement of air quality,then promote the urban ecological environment and improve the quality of life provided high,which is of great significance for urban sustainable development.
