(中国电力科学研究院,北京 100055)[摘 要] 以电力设施在Ⅱ类场地条件下50年超越概率为2%的抗震设防为原则,结合《全国地震动参数区划图》的分区方法,以ArcGIS为平台绘制完成了全国及各个省的电网抗震设防分区图。详细介绍了其绘制过程和主要技术方法,得出了绘制流程图,总结了绘图过程应用ArcGIS技术的意义。该系列图的应用将为电力设施的合理规划提供决策依据。[关键词] ArcGIS; 分区原则; 绘图流程; 技术方法中图分类号:P315-39 文献标识码:A 文章编号:1002-848X(2013)S2-0449-04Mapping study of the national and provincial power system for seismic for tification partition based on ArcGISFang Zhenggang, Zhong Min(China Electric Power Research Institute, Beijing 100055, China)Abstract: According to the principle of exceedance probability of 2% for 50 years inⅡsite conditions, Combining the division method of the national seismic ground motion parameter zonation map, basing on the ArcGIS platform, the author drawn the nation and provincial power system for seismic fortification partition map. The paper introduced the drawing process and main technical methods in detail, gained the drawing output, summarized the significance of using ArcGIS technology during drawing process. The applications of the series map will provide the decision-making basis for rational planning electric power facilities.Keywords: ArcGIS; Principle of partition; Mapping process; Technical method
