“气泡城市”运用生态布局防治雾霾的方法探索与研究

Research on the Method of Using Ecological Layout to Prevent Haze in “Bubble City”

"气泡城市"是将城市气流比作人类呼吸,利用夏冬两季的不同风向结合城市生态布局来打造的城市空间概念。这个概念能让城市在吸进夏季清新空气的同时呼出冬季空气中的颗粒物,从而实现环境健康的目的。所以这套理论也可被称作"绿肺城市"或"呼吸城市"。"气泡城市"原理的核心是利用"绿色风道"和"防霾屏障"打造可持续循环的城市小气候。"气泡城市"的具体措施是利用源头控制、引流屏蔽、路径过滤、光合蒸腾、流通排出五个技术手法共同打造的。"气泡城市"在空间级别上可从宏观、中观、微观三个尺度进行分析研究。总的来说,"气泡城市"是为如何治理城市雾霾而提出的一套风景园林参考性建议。

The conception of bubble city is a brand-new solution to shaping urban space by means of the different directions of the monsoon in different seasons,combined with the urban ecological layout,as if the whole city were breathing as a lung.This new solution focuses on making the city as lungs,breathing in the fresh air in summer as well as breathing out the particles in the air in winter,in order to achieve the aim of ecological health.As a result,the theory of this solution can be named Green Lung or Breathing City.The core principle is to build up a recyclable urban microclimate with Green Air Corridor and Smog Barrier Layer.The research applied five concrete measures,origin control,guidance shield,path filtering,photosynthesis transpiration and current discharge.Bubble city in this research is analyzed in distinct from three space views of macroscopic,medium and microscopic.In brief,bubble city is a series of landscape suggestion used to control the urban smog.
