China is blessed with abundance of crop straw,of which the disposal by burning in open fields results in waste of resources and serious air pollution forming haze. The practice in Jiangsu was cited as a case for study. A "pressurestate-response"(PSR) model was developed based on the Boston matrix and used to analyze the air pollution caused by open-airstraw burning in 13 prefecture-level cities of Jiangsu Province during 2010- 2012 for pressure,state and response of the practice. Results show that although Jiangsu Province achieved remarkable results in banning open-air straw burning,the pressure of banning the practice to reduce air pollution was still quite high in almosthalf of the cities,and in most of the cities still existed much room for improvement of comprehensive utilization of straw resources. In Nanjing,attention should be given to comprehensive utilization of crop straw,which should be improved in comprehensive utilization level. In South Jiangsu,the crop straw utilization rate was quite high,but there was still much room for improvement of the utilization,However,it is still essential to enforce the policy of banning straw burning in open fields. In Central Jiangsu,the utilization of crop straw resources was rather simplex in method,so is necessary to shift its focus on multiplying ways of crop straw utilization. In North Jiangsu,the pollution pressure from straw burning was very high. Therefore,rigid policies of banning straw burning should be enforced along with development of comprehensive utilization of its crop straw resources.
