On the Construction of Urban Ventilation Corridors Under the Theory of"Source-sink"Thermal Landscape:Taking the Main Urban Area of Hefei City as an Example
摘要
Abstract
Scientific construction of urban ventilation corridors plays an important role in alleviating urban heat is-land effect.Taking the main urban area of Hefei city as an example,the"source-sink"thermal landscape theory was used to extract the starting and ending points of the ventilation corridor,and the MCR model and gravity model to analyze and screen the ventilation corridor,so as to construct the ventilation corridor network in the study area.The results show that the starting patches are mainly concentrated areas of reservoirs,wetland parks and forests,and the ending patches are mainly urban built-up areas.A total of 13 first-level corridors and 9 second-level corridors were constructed,with a total length of 312.44 km.Under the dominant wind direction in summer,all the other heat source patches except Y5 could introduce cold air from 2 or more heat sink patches through the primary corridor.The introduction of"source-sink"theory can enhance the connection of urban ventilation corridors to urban cold source and heat source areas,and enhance the efficiency of urban ventilation corridors.关键词
