利用组件GIS和构件技术建立林业GIS系统

Forestry GIS establishment based on component GIS and member technology

随着计算机技术的进步,以林业GIS系统为代表的林业信息化进程得到前所未有的发展,但也存在着工程重复建设的问题,没有按统一的标准、规范和要求进行,特别是林业专业模型的实现一直进展缓慢。本文将软件复用的思想引入到林业GIS系统专业模型的构件设计与开发上,通过组件GIS技术与构件技术相结合的方法实现林业GIS系统功能的复用,大大节约了林业GIS系统的开发成本,提高了开发效率。

With the development of computer technology and the digital process of forestry, the GIS of forestry has been established rapidly in many areas. But there are also many problems which exist in the GIS application system development of forestry currently. For example, engineering （hardware and software） is constructed repeatedly, does not follow the unified standards, norms and requirements. This research introduced the thought of software reuse in system development combined with the technology of GIS component and member to establish the reuse functions of forestry GIS system. And according to the requirements of forestry GIS function, it made the domain modeling. It was proved that the method could improve the efficiency of forestry management greatly.
