摘　　要：运用GIS空间数据可视化技术和Python语言可视化模块对我国近十年间发生地震的POI大数据进行可视化分析,通过对地震发生的历史数据进行分析,探究和揭示地震发生的一些时空规律。分析结果表明:近十年地震主要发生于我国地震板块的天山地震区、昆仑山地震区、青藏高原地震区以及台湾地震区,主要涉及地区有新疆、四川、云南、青藏高原以及台湾地区;地震的分布方向以及聚集中心分布明显,地震级数以3—6级居多,地震深度以0—50 km最为常见。分析结果可以给地震发生区域的有效应对提供参考。In this paper,GIS spatial data visualization technology and Python language visualization module are used to carry out visual analysis on POI big data of earthquakes in recent ten years in China.In order to explore and reveal some spatial and temporal laws of earthquake occurrence,the historical data of earthquake occurrence are analyzed,and the analysis results show that:in the past decade,earthquakes mainly occurred in the Tianshan mountain area,Kunlun mountain area,Qinghai-Tibet plateau area and Taiwan earthquake area,the main areas involved are Xinjiang,Sichuan,Yunnan,the Qinghai-Tibet plateau and Taiwan.The distribution direction and aggregation center of earthquakes are obvious.The earthquake series are mostly 3—6 magnitude,and the earthquake depth is 0—50 km.The analysis results can provide reference for the effective response of the earthquake area.
