【Abstract】 With digitization small water conservancy project at county level as research object, the article researchs its information characteristics and several key technologies in its software development. It includes that second development programming based on ObjectARX and VLISP, connection and applications with external general database (ACCESS), SQL programming and so on. It could solve several problems of base data warehousing and into the figure, testing of its veracity at small water conservancy project, inquiring of hydraulic structure CAD drawing, data’s uniform and refresh and so on. It effectively manages the word and graphic information at county level small water conservancy project. It also initially explored the problem about CAD data transform to geographical information system. The small water conservancy information management system for county project is effective and easy to use.更多还原
