Research on the Adaptability Planning Model of Low-carbon and Ecological Residential Areas in Chongqing under the Urban Microclimate Environment

With the global climate change, further study should be done on the relationship between space environment and urban microclimate environment of residential areas, and it is going to improve the suitable degree of settlements by improving and using the microclimate environment in residential areas. By the study, the low-carbon and ecological residential areas with adaptability will be planned, it can lay a foundation for relieving global climate problems by energy saving, emission reduction and environmental protection. Firstly, this paper evaluates the existing settlements practice of the Chongqing, analyzes the planning adaptability of mountainous residential areas in Chongqing and summarizes the relationship between plans and mountainous terrain environment, ecological environment and microclimate environment. Secondly, by taking four constraints factors (Heat, Ventilation, Humidity, Sunlight) affecting mountainous urban micro-climate cycle as the evaluation factors, the paper summarizes the three planning models includes adaptability of mountainous layout, characteristics of mountainous buildings and organization of mountainous green space. Taking the three facts as three vectors, to establish the 3D coupling model representing low-carbon and ecological performance, and by coupling, "the Adaptability Planning Model of Low-carbon and Ecological Residential Areas in Chongqing" can be obtained, then it can guide the direction of low-carbon and ecological planning in mountainous city.
