（中國電力科學(xué)研究院，北京 100055）[摘 要] 以電力設(shè)施在Ⅱ類場地條件下50年超越概率為2%的抗震設(shè)防為原則，結(jié)合《全國地震動參數(shù)區(qū)劃圖》的分區(qū)方法，以ArcGIS為平臺繪制完成了全國及各個省的電網(wǎng)抗震設(shè)防分區(qū)圖。詳細(xì)介紹了其繪制過程和主要技術(shù)方法，得出了繪制流程圖，總結(jié)了繪圖過程應(yīng)用ArcGIS技術(shù)的意義。該系列圖的應(yīng)用將為電力設(shè)施的合理規(guī)劃提供決策依據(jù)。[關(guān)鍵詞] ArcGIS; 分區(qū)原則; 繪圖流程; 技術(shù)方法中圖分類號：P315-39 文獻(xiàn)標(biāo)識碼：A 文章編號：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
