Study For Spatial Plan In Caiyu Town On Urban-climate Environment Optimization

Climate and urban construction activity are closely related to each otherand influence each other. On the one hand, geographical latitude, terrain, andother natural elements shaped regional climates, and then, wind, sunshine,temperature, precipitation, humidity affected the location, construction andlayout of town. On the other hand, urban construction activity also had animportant influence on local climate. The development of city made urban formchange greatly and anthropogenic heat grow continuously, which changed theproperties of underlying surface in city, influenced the natural climate, andgradually created a special urban climate conditions.In recent years, with rapid urbanization, the problem of urabn climate inBeijing-Tianjin-Hebei region is becoming more and more serious, whichchallenges the healthy development. Dust in spring, high temperature and heavyrain in summer, and haze in winter, which are all closely related to climate,have been widely concerned. Besides that, deterioration of urban climateenvironment will improve the frequency of using air conditioning equipment,and increase energy consumption, which play a negative role on global climatechange. Therefore, paying more attention on the relationship between climateand urban construction activities in the process of planning and design, andlooking for a way to construct a reasonable urban system which will improvethe climate environment based on integrated natural climate condition is thepurpose of this paper.Caiyu Town is located in the southeast of Beijing, and also in the Beijing-Tianjin Development Axis. It is an important part of Yongle, which is a spareland for development in Beijing. Caiyu is adjacent to Langfang that is in HebeiProvince, Wuqing which is in Tianjin, and closely linked to Daxing new town,Yizhuang new town. It is also one of the important small towns in Beijing,which will play a major role on urbanization in this area. Based on actualengineering project about Caiyu Town, this paper will study how to improve thelocal climate environmen from the perspective of urban planning in thebackground of regional climate deterioration.
