| 摘 要： | 区域管理信息系统是为区域规划、管理和决策服务的。经调查研究和系统设计,系统的数据分类体系一般需要7—8级分类才能把有关专题图上最小图斑的内容或属性表示出来。7—8级分类体系中最高的3级分类为高位分类,是各级区域管理信息系统中必须具有的分类。低位分类是第3级高位分类的细化,具有更强的学科性。由于它涉及的学科繁多,各专题分类形式各异。最后决定用32位数字组成区域管理信息系统的数据分类编码,其含有高位分类码、低位分类码、区位码、时间码、顺序码和机动码,分别占用4、8、6、6、4和4位码。便于各级区域管理信息系统之间的数据共享和交换。

| Abstract: | Regional Management Information System(RMIS) gives service to regional planning, management and decision-making. According to the investigation and system-design, the data of RMIS is classified as 7-8 levels that representing the attribute of the smallest pattern on a thematic map.. The highest 3 levels are the essential high-rank classification for each RMIS. The low-rank classification is the perfection of the 3rd high-rank in detail with moce professional knowledge. As it deals with a wide range of disciplines in which there are many different forms of every thematic class. 32-digital number is used to data classify and coding in RMIS. The classified and coded format for RMIS includes high-rank code, low-rank code, location code, time code, order code, and flexible code that each occupies 4,8,6,6,4 and 4-di-gital number respectively. Thus, it is convenient to share and exchange the data of all levels for RMIS. |
