Research on Architectural Pattern of Residential Quarter Based on Atmospheric Pollutant Diffusion of Point Source

摘要

In the process of rapid urbanization, many pollution problems arise in developing cities. In particular, industrial point source air pollution is one of the main causes that detract from urban development and destroy ecological harmony. Gas pollution directly affects people's physical health when a source of industrial emissions is close to residential areas. In the planning and design of sustainable architecture, it becomes increasingly important to avoid industrial atmospheric diffusion pollution in the broadest sense through studying the layout of urban residential architecture group. This paper establishes the database of atmospheric pollution diffusion based on the ArcGIS platform. Through simulating the spatial distribution state of the atmospheric point source pollution concentration in Nanjing Chemical Industrial Park, the spatial information of urban atmospheric environmental quality can be provided for the layout and planning of the neighboring residential quarter. Combining with CFD wind field simulation of different architectural layouts, this paper studies the adaptive layout of residential architecture on surrounding environment. The results show that the pollutants' concentration in summer is slightly lower than in winter; the pollutant concentration of determinantal layout is lower than the oblique column type and alternate layout in Shanpan Community. It explores the relationships among urban residential architecture, people and natural environment, and the results are very important in conducting the pattern planning and design of urban architecture, improvement of living environmental quality and energy conservation and environmental protection.
