In present China, both the national policy and market of housing system are in the process of perfecting, which pay more attention to the low-income residents and rural residents. This paper chooses Tianjin, the third pole of China development as the example for research. Tianjin public housing residential district planning explored a mode of ＂large-scale mix and small-scale pure＂ for the whole homeland development. It confirms that regional coordination, ecological concepts, green transport, space characteristics and appropriate technology is important in planning.展开更多

Most scholars believe that the haze is toxic and harmful gases; particulate matter and other pollutants together lead to reduced visibility as the main manifestation of the phenomenon of air pollution. Population health effects caused by the haze have been proven in many studies. The system summarizes the polluting haze weather physicochemical characteristics, introduced widely accepted definition of haze, haze hazard to residents and the proposed requirements.展开更多
