| Component software technology is a new kind of software engineering technology that developed after and as an entension of the object oriented technology. A new concept has been put forward since the rising of component software technology which has already become one of the trends in current software technology. The use of compoent GIS has provided opportunities for the innovation and improvement of various GIS application systems . Component GIS is a kind of application of object oriented technology and component software in GIS software development. It properly abstracts GIS functions and provides them to users as components, which makes it take on many advantages that the traditional GIS lacks. Therefore, it provides completely new idea to solve the problems that traditional GIS faces.Though component GIS has been widely used in many fields, its application in the area of rural power distribution network management in China is currently seldom. In this paper, the development of geographic information system and the current research hot topics were reviewed, the principles of component technology and its feature, the structure of component GIS and the method of its redevelopment were discussed in detail. This paper alse compared the systems based on traditional GIS and component GIS seperately. And the system analysis, system design and system implement of rural power distribution network management developed by component GIS were studied particularly.Based on the above theoretical research, this paper applied component GIS method to develop the rural power distribution network management system of Baoding city.Laishui county as a case of practical application. In the advanced visual programming language-Visual Basic 6.0 development environment, we took advantage of America GIS component-MapX4.5 to have implemented GIS functions of the system in space data gathering,management,disposition,analysis, output,etc.
