| 摘 要： | 鉴于重大自然灾害为非孤立存在，且同一区域内发生重大自然灾害往往为有联系的灾害事件群，在掌握灾害基本信息后分析其时空对称性规律，为今后部分重大自然灾害发生趋势研究提供了参考。在时间对称性方面，主要采用可公度信息提取方法和“蝴蝶结构图”法对部分重大自然灾害进行趋势预测，案例分析结果表明：乌鲁木齐2011年发生Ms≥5．6级...

| Abstract: | It is difficult to predict and forecast several natural disasters currently.Major natural disasters frequently occurred synchronously.Several major natrual disasters generally occurred as one disaster incident group in a region.In this paper,we proposed the law of time-space symmetry of disasters,based on the basic information of each disaster.In the aspect of time symmetry,we carried out both the method of commensurability information extraction and Map of Butterfly Structure(MBS).We improved the commensur... |
