| 摘 要： | 将青藏高原北部地区划分为祁连山地震带、甘东南地区、库玛地震带和柴达木一共和地块4个研究区域，基于古登堡一里希科特的震级一频度关系和震级一序号图像法对每个区域1970年以来的小震目录进行完整性分析，分别确定不同区域、不同时段的完整小震目录的震级下限，其结论可供青藏高原北部地区地震活动性分析和地震危险性评价研究时参考。

| Abstract: | The north region of Qinghai - Xizang plateau is divided into four studied areas which are Qilianshan earthquake zone, southeast region of Gansu province, Kusaihu-Maqu earthquake zone, Caidamu-Gonghe block, and minimum magnitude of completeness in earthquake catalogs in each area since 1970 are analyzed by Gutenberg - Richter magnitude-frequency relation and magnitude-Ordinal pattern, and the magnitude lower limit is determined in different areas and in different periods. This results may be for seismicity and earthquake risk evaluation reference in the studied areas. |
