面向特大城市的风环境容量指标和区划初探 ——以北京为例
Indexes and Zoning Research of Wind Environmental Capacity for Metropolis—A Case of Beijing
摘要
Abstract
Based on the meteorology observation, high resolution urban geographic information and satellite remote sensing data, as well as taking account of the meteorology and urban factors, the results of the wind environmental capacity indexes and zoning in Beijing show that, both the wind speed and mixing layer height are higher in the north and east regions, while lower in central city and southwest areas. The surface roughness length is higher in central and satellite cities, while smaller within the 2nd ring road than in other central urban areas because of the effect of many bungalows distribution, which forms an obvious hollow and ring structure. In the northern and western mountain districts, the roughness length is higher than that in plain areas.Weighting and overall considering the three factors of wind speed, mixing layer height and roughness length, the wind environmental capacity index thresholds were calculated at different levels. It is lower in Fangshan, Mentougou, Haidian, Shijingshan, Fengtai, Dongcheng and Xicheng, especially the capacity index is the lowest in the region between the 2nd ring road and the 4th ring road, which is also consistent with the spatial distribution of Beijing's economic, financial and commercial centers. The high value of wind environmental capacity index is mainly distributed in the northern part of Yanqing, Huairou, Miyun and almost whole Tongzhou district, while other plain areas belong to medium wind environmental capacity index.关键词
