摘　　要：随着现代化城市建设,城市管网系统日趋复杂,管道事故发生频率不断增加,导致严重经济损失,对城市居民的正常生活造成较大影响。因此,对于城市管线事故信息的可视化与事故时空分布情况的了解与分析就变得尤为重要。面向互联网上的事故新闻,从文本中提取管线事故信息,构建管线事故地理场景,并建立管线事故地图数据库与地图可视化系统。根据现有数据对事故发生时空分布规律进行分析,发现其在局部存在一定的空间聚类特征。时间上,事故高发期为5月至7月,同时9月至12月事故的发生频次呈上升趋势。With the construction of modern cities, in that the urban pipe network system is becoming more and more complex, the frequency of pipeline accidents is increasing, which leads to serious economic losses and has a greater impact on the normal life of urban residents. Therefore, tasks such as the visualization of urban pipeline accident information and the understanding and analysis of the temporal and spatial distribution of accidents have become particularly important. This paper extracts pipeline accident information from accident news texts on the internet and constructs a pipeline accident geographic scene. It establishes a pipeline accident map database and a map visualization system according to the scene. In the spatial dimension, it is found that pipeline accidents have certain spatial clustering characteristics in the local area. In terms of time, the high incidence of accidents is from May to July, and the frequency of accidents from September to December is on the rise.
