摘　　要：以吉林省汪清林业局为例 ,介绍了基于 Power Builder和 Map Info的汪清林业局地理信息系统的建立与应用。该系统将空间信息库和其属性信息库 (小班数据等 )紧密地联系在一起 ,相互查询 ,同步更新 ,给决策者随时提供最新信息 ,避免了以往资源数据库和图形库相脱节的状况 。Taking Wangqing Forestry Bureau in Jilin Province as a example, the procedure of development and application of Geographic Information System of Wangqing Forestry Bureau was introduced based on MapInfo software. In this system , the attribute information and space distribution information are connected reasonably and correctly and can be updated simultaneously by ODBC and DDE function of MapInfo which is easy for users to inquiry or modify mutual information between the space distribution and region attribute of forest. This new characteristic can successfully solve the traditional problem --separation between attribute information and space distribution information. By using this system, the decision makers can get the up to date forest information and make forest resource information management to meet the need of forestry sustainable development.
