摘　　要：突发性环境事件省际格局变动趋势特征可表征各地区环境风险管理成效及存在问题。研究揭示:(1)1996-2010年间,中国突发环境事件省际分布格局发生了较大变化,年均发生频率明显下降;(2)东部省区突发水污染事件控制效率高于西部和中部省区,但大气、固废及其它类型的突发环境事件东部治理成效却远低于中西部省区;(3)大部分省区发生频率呈下降态势,而上海、北京、重庆等地发生频率却呈增加态势,显示大城市环境风险预防、监控、管理能力发展滞后于城市化进程。The research on the changing spatial provincial patterns on environmental accidents reflects the efficiency and problems of environmental risk management in different regions.Some facts have been discovered by data analysis on suddenly-happened environmental accidents in China from 1996 to 2010:①the annual frequency of accidents decreased obviously and the spatial distribution pattern has changed obviously;②the frequency declined rapidly in most provinces,but other regions increased such as Shanghai,Beijing and Chongqing;③the east China Shows the higher efficiency than the west and middle China in water pollution Prevention,but lower efficiency in air,solid and other-types pollution.
