Abstract:Based on the Pressure-State-Response (PSR) model, the environmental carrying capacity assessment methods were applied to analyze water environmental carrying capacity evolution of 16 cities in Yangtze River Delta Region. Corresponding to the logical relationship among press, state and response, suggestions for improving environment carrying capacity have been put forward. During 2005 to 2010, the carrying capacity of cities in the Yangtze River Delta had shown various levels of improvement, but the overall situation still serious. In addition, there was imbalance of carrying capacity within regions and watersheds, which mean, the carrying capacity of cities in Zhejiang province was significantly better than that of cities in Jiangsu province and Shanghai, and the carrying capacity of cities locate in the south of Taihu Lake was better than those to the north and to the east. Carrying capacity was mainly decided by city’s environmental capacity, pollution emission baseline and the efficiency of pollution control actions. Guided by the principle of continuously pollution reduction, city layout optimization and efficiency increasing, cities in the Yangtze River Delta should reduce the pressure on carrying capacity, improve its status and promote its response.
