EDCM(Electrical Distributed Circuity Management) GIS(Geographic Information System) is based on management of spacial information that determinded by geographical location ,which is a modern technical way for operation and management of Electrical Distributed Circuity. To make the system more maintainable and more flexible so as to meet the demands of practical production and circuity management,this thesis proposes a method that based on DB templates design.It briefly introduces the conception and characteristics of template and discusses its implementations in GIS,then it analyses emphatically 8 templates(device,symbol,accessory,connection,parameter,report,group and rule)next it discusses the relationships and describes the meanings of them.Also its data organization and technique diffculty suggest a method using tables to store device DB and accessory DB.Then it presents an example based on MapGis platform .Finally considering the application of this method,its merits was discussed and its development scope was forecasted.
