主　　题：air pollution index (API) air environmentbearing capability key city assessment method 

摘      要：Given the complexity and time-consuming of the conventional environmental capacity based assessment on air environment carrying capacity; a new method for assessing urban air environment carrying capacity based on air pollution index （API） is presented. By using this new method, the air environmental beating capability of 333 cities at the prefecture level and above is assessed. The results show that of the 333 cities 9.6% is of high beating capability, 34.5% relatively high beating capability, 52.6% medium beating capability, 2.7% low capability, and 0.6% is of weak beating capability; in terms of regional distribution, the western region is of relatively high air environment bearing capability, followed by north-eastern and eastern regions, and the ambient air quality in the middle region is quite poor; among the 12 urban agglomerations in key regions, Pearl River delta, west side of Taiwan Strait and Chengdu-Chongqing agglomera- tions are of relatively high carrying capacity while other agglomerations are of medium beating capability. The assessment results imply that the existing air quality standard （GB3095-1996） is quite unsound.
