Social effect of environmental pollution on valley-cities in western China

Accompanied with the acceleration of urbanization and industrialization, the large and medium-scale valley-cities in the western China are facing environmental problems at respective levels in common. The urban environmental pollution causes economic losses, and also brings out negative effects on urban society. Based on the social investigation method, this paper aims to study the harms to urban society brought by environmental pollution. After the investigation to the inhabitants of six typical valley-cities: Lanzhou, Xining, Chongqing, Baiyin, Luzhou and Zigong, we found that the urban environmental pollution has resulted in negative influences with different levels on residents' physical, psychological, work, recreations, studies and social activities. The problem of environmental pollution has become a serious restriction to sustainable development of cities mentioned above. Herewith, it has become urgent to strengthen the government regulations for controlling urban environmental pollution.
