Based on 569 accidents of hazardous chemicals accidents happened in China during 2011-2013, the rea-sons, characteristics and laws of those accidents were statistically analyzed on aspects including occurring time , oc-curring location , physical appearance , hazardous chemicals categories and occurring stage etc .The results showed that for hazardous chemicals accidents , the prone months are from April to August; more accidents happened in provinces with the dominant petrochemical industries , such as Zhejiang, Jiangsu, Shandong, Hubei, and Sichuan;production and transportation are the main stages of the accidents .At production stage , 10:00-12:00 and 17:00-18:00 are the period of time which has high frequency of accident , the main type of accident is explosion accident , and the important causes leading to the accidents are defects of equipment and human factors .At transportation stage, the high frequency accident happens at the period of 1:00-12:00;leakage accident occurs more easily than any other types in this stage .Based on the statistic analysis , some corresponding countermeasures for reducing the number of hazardous material accidents were proposed .%统计了2011年1月～2013年12月我国发生的569起危险化学品事故，从危险化学品事故的发生时间、发生地点、事故物理表象、危险化学品类型、发生的环节及原因等方面进行了统计分析。结果表明：4～8月份是危险化学品事故多发月份；浙江、江苏、山东、湖北、四川等省份为危险化学品事故高发省份；生产和运输环节是危险化学品事故发生的最主要环节；在生产环节，10：00～12：00及17：00～18：00是事故高发的时间段，其中爆炸是事故最多的类型，而机械的不安全状态及人为因素是事故发生的最主要因素；对于运输环节，1：00～12：00是事故的高发时段，泄漏是事故发生最多的类型。最后，基于统计结果提出进一步减少我国危险化学品事故的相关对策建议。
