【摘要】:随着对城市可持续发展和城市品质的关注,作为改善城市环境品质与消减热岛效应的重要途径的通风廊道规划建设逐步走进人们的视野。以安庆市中心城区为例,借助PHOENICS软件中的FLAIR模块,运用流体动力学分析方法对研究范围的通风廊道采取"城区—分区"的研究思路进行分类研究。城区层面,识别出通风口地区和一二级风道,并将通风口地区划分为建设用地区和非建设用地区,分别提出相应的管控策略。分区层面,进一步识别出三级风道。对应新、老城区需要解决的实际问题,采取差异化的研究思路:老城区以"改善现有的通风环境"为目标,针对通风环境较差的地区,提出近远期不同的改善策略,简称为"亡羊补牢"。新城区以"保障未来形成良好的通风环境"为目标,针对识别出的一二三级风道沿线地区,从宽度、建筑密度、阻风率、高宽比和开放度等方面提出控制指标要求及规划策略,总结为"未雨绸缪"。通过探索针对城市内部不同地区的差异化通风对策,以期对今后其他地区城市通风廊道的规划研究提供参考。
[Abstract]:Along with the attention to the sustainable development of the city and the quality of the city. As an important way to improve urban environmental quality and reduce heat island effect ventilation corridor planning and construction step by step into the vision of people. Take Anqing City as an example. With the help of FLAIR module in PHOENICS software, using the method of hydrodynamic analysis, the ventilation corridor of the study scope is classified and studied by the idea of "city-zoning". Identify the air vent area and the first and second grade wind passage, and divide the air vent area into the construction area and the non-construction area, and put forward corresponding control and control strategies respectively. At the regional level, further identify the third level wind channel, corresponding to the new. The actual problems that need to be solved in the old urban area, adopt the different research idea: the old city takes "improving the existing ventilation environment" as the goal, aiming at the area with poor ventilation environment, put forward different improvement strategies in the near and long term. The new urban area aims at "ensuring a good ventilation environment in the future" and aims at the identified area along the 123 grade wind track from the width, building density and wind resistance rate. In the aspect of aspect of aspect such as aspect of aspect of aspect of aspect of aspect of aspect of height to width and open degree and so on, put forward the control index request and planning strategy, summarize for "make good plan ahead of time", through exploring the differential ventilation countermeasure aimed at different area of the city. In order to provide a reference for the planning and research of urban ventilation corridors in other areas in the future.
