| Forestry information has become an inevitable trend of development of forestry, forest resource management system which is an important component of the forestry information developed rapidly. By summing up status and trends of the current forest resources management system, In view of the current forest resource management system development problems in design, combined with the trend of its development, To forest management inventory data in the area of Dr. Sun Yat-sen Mausoleum for the study, this paper establishes a forest resources management system.Plug-in technology-based framework for forest resources management system, the development will be divided into system platform, the database of forest resources, the development of functional plug-ins in three parts. Through .Net Framework 2.0 to provide a variety of methods and technologies for plug-in technology-based system framework, without recompiling the system, we realize how to dynamic manage system plug-ins such as loading and removing the plug-ins.This provides an effective mechanism for the system update, the expansion of functions. In building a database of forest resources, for providing a solution of sharing forest resources data, the study extracted metadata from the existing data-sharing standards and norms of forest resources. Using the technology of metadata and ESRI GeoDatabase forest resources database has been established. In addition to improving the system, the study not only used ArcGIS Engine as secondary development components to realize basic factional plug-ins, but also integrated professional analysis model of forest resources into system which enhances the system capacity to support decision-making.In this paper, the ideas of the development of forest resources management system, new technologies in support of, try to export the way to improve the traditional development method and this study to other forestry information systems also have some reference. |
