摘要
历史文献中有关地震的文字记载是研究地震发生规律与灾害特征的重要依据。通过统计、分析288～1949年间广西地震的记录数据，可以看出历史时期广西地震的发生受到活动性断裂严格控制的趋向，在空间方面表现为北东和北西向分布的“X”型特征。在时间方面，则呈现周期性的起伏变化，显示相对平静和显著活跃相互交替的特点。陷落性地震常见、易受临近区域强地震带影响等现象，也颇引人注目。
The letters about the earthquake in history document are vital materials for researching its rules and disaster characteristics. From analyzing the earthquake data in Guangxi from year 288 to 1949, it can be concluded that the earthquake of Guangxi in history period is influenced by active rift and indicates as the spatial distribution of northeast and northwest with the characteristics of ＂X＂. As time goes, it is shown as seasonal change and with the interactive characteristics of relative calm and dramatic activity. Collapse earthquake is common, which is ease to be influenced by nearby strong earthquake, and has att racted a lot of attention.
