【摘要】 中国第四纪以来灾害的不断频发,除与备受关注的人类活动有关外,第四纪环境背景演化也为灾害的发生提供了必要条件.根据中国灾害类型的多样性和差异性,结合主要致灾因子和灾害损失程度,进行分区,在此基础上研究各区灾害与第四纪地质—地貌环境、大气环流环境等的关系,这将有利于减灾战略措施的正确制定.更多还原

【Abstract】 The disasters were occured frequencly during the Quaternary Period,and it was one of the significant characteristics of the Quaternary Period. It not only resulted from human activities,but also from the evolutional background of the Quaternary Period.Based on diversity and difference of the types of disaster and combined the main disaster causing factor and disaster losses,the disaster regions of China were divided into some districts.According to different regions,the relationship between the Quatemary geological-geomorphic environment and the atmospheric circulation environment was studied.It could be as the basis of stratagems for mitigation disaster.更多还原
