城市道路绿化空间模式逻辑推演及微气候环境分析

Logical Deduction of Urban Road Green Space Model and Analysis on Microclimate Environment

城市道路作为与人们日常生活联系最紧密的公共空间,其绿化形式对改善城市微气候环境至关重要。现有的规范偏重于对道路绿化平面形式和指标的规定,而与城市微气候环境关系最为密切的是道路绿化的断面空间形式。本文借鉴三段论的形式,推演出道路绿化空间逻辑上可能出现的97种模式,并从人性化的视角对几种典型模式的微气候环境进行比较分析,从中筛选出21个强式、27个中性式、24个弱式和25个无效式。最后针对绿化空间的优化模式筛选出适宜性树种,以期为城市道路绿化设计提供参考。

As a public space closely related to people’s daily life,the greening form of urban road is crucial for the improvement of the urban microclimate environment.The existing norms focus on the provisions on the plane form and index of road greening.However,the thing that is most closely related to the urban microclimate environment is the section space form of road greening.This paper uses the form of syllogism for a reference to deduce 97 possible modes of road greening space logic,compares and analyzes several typical modes of microclimate environment from the perspective of humanization,and then selects 21 strong modes,27 neutral modes,24 weak modes and 25 invalid modes.Finally,the suitable tree species are selected according to the optimization model of green space,in order to provide a reference for urban road green design.
