摘要
科学构建城市通风廊道对缓解城市热岛效应有着重要作用.以合肥市主城区为例,利用"源-汇"热景观理论提取通风廊道起终点,MCR模型和重力模型分析并筛选通风廊道,构建研究区通风廊道网络.结果表明:起点斑块以水库、湿地公园、森林的集中区为主,终点斑块以城市建成密集区为主;共构建 13 条一级廊道,9 条二级廊道,全长312.44 km;在夏季主导风向下,除Y5 斑块外的其他热源斑块均能够通过一级廊道引入 2 个及以上的热汇斑块的冷空气;"源-汇"理论的引入可以增强城市通风廊道对于城市冷源和热源区域的联系,加强城市通风廊道的效能.
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.
