【摘要】：随着云南省国土资源信息化建设的迅速发展,现云南省国土资源厅已积累了海量的国土资源数据,包括大量宝贵的基础测绘数据、土地专题数据和矿产资源环境数据等。但是由于这些数据来源多样,格式不一,存储位置分散,加上有些数据年代已久,建库时没有统一的标准,导致数据情况十分复杂。多源、多格式、多比例尺的数据严重影响了其综合分析与应用,难以发挥其拥有的巨大价值。怎样集成应用分散、独立的国土资源信息,使其更好的为国土资源管理决策服务,并提供网络化的社会服务,是目前迫切需要解决的问题。针对这些问题,论文从研究制定相关数据标准规范入手,采用信息资源规划的方法,围绕国土资源管理应用需求和实际,对不同类别、不同专业的海量、多源、异构数据进行分析、归类、整合、入库,并建立规范统一的数据更新和共享机制,构建云南省国土资源“一张图”核心数据库。本文首先对云南省国土资源信息化建设现状做了调研,梳理了现有的国土资源数据,然后按照国家标准、省级标准和行业标准制定了云南省国土资源数据标准,根据制定的标准规范,整合云南省现有的国土资源数据,将多源多尺度多时段的国土资源数据整合成为统一标准的数据资源；利用信息资源规划的方法,基于行政管理的实际应用和需求,自顶向下的梳理国土资源业务流程,完成业务流程图和数据流程图,并利用企业总体架构的方法对云南省国土资源“一张图”核心数据库进行整体框架模型设计；将整合好的数据资源入库,并建立统一规范的数据更新和共享机制,为国土资源各个管理信息系统提供支持；最后,以云南省电子政务系统为例,介绍云南省国土资源“一张图”核心数据库是如何为其提供应用支撑的。综上所述,本文以满足云南省国土资源管理实际应用为主线,经过对现有数据分析,提出云南省数据标准,并采用自顶向下的方法设计核心数据库架构,利用信息资源规划的方法,完成数据建模,最终实现云南省国土资源“一张图”核心数据库的建设,对推进云南省国土资源信息化建设具有实际意义。
[Abstract]:With the rapid development of the information construction of land and resources in Yunnan Province, the Department of Land and Resources of Yunnan Province has accumulated vast amounts of land and resources data, including a large number of valuable basic surveying and mapping data. Land thematic data and mineral resources and environmental data, etc., however, due to the diversity of sources, the format of these data, the scattered storage locations, and the fact that some of the data have been in existence for a long time, there is no uniform standard for the establishment of the database. The data situation is very complicated. Multi-source, multi-format, multi-scale data seriously affect its comprehensive analysis and application, it is difficult to play its great value. It is urgent to solve these problems by providing better service for land and resources management decision-making and providing social services based on network. In view of these problems, this paper starts with the research and establishment of relevant data standards and norms. Using the method of information resource planning, according to the requirement and practice of land and resource management, the author analyzes, classifies, integrates and puts into database the massive, multi-source and heterogeneous data of different kinds and different specialties. A standardized and unified mechanism of data updating and sharing is established, and the core database of "one map" of land resources in Yunnan Province is constructed. In this paper, first of all, the present situation of land and resources informatization construction in Yunnan Province is investigated, and the existing land and resources data are combed out. Then, according to the national standards, provincial standards and industry standards, the paper formulates the Yunnan land and resources data standards. According to the established standards and norms, integrate the existing land and resources data of Yunnan Province, integrate the land and resources data of multi-source, multi-scale and multi-time into unified standard data resources, use the method of information resource planning, Based on the practical application and demand of administrative management, combing the land and resources business process from top to bottom, completing the business flow chart and data flow chart, Using the method of enterprise's overall structure, the paper designs the whole frame model of the core database of "one map" of land and resources in Yunnan Province, puts the integrated data resources into the database, and establishes a unified and standardized mechanism of data updating and sharing. Finally, taking the E-government system of Yunnan Province as an example, the paper introduces how the core database of "one map" of land and resources of Yunnan Province provides the application support for it. To sum up, this paper takes the actual application of land and resources management in Yunnan Province as the main line, through the analysis of the existing data, puts forward the data standard of Yunnan Province, and adopts the top-down method to design the core database architecture. By using the method of information resource planning, the data modeling is completed, and finally the construction of the core database of "one map" of land and resources in Yunnan Province is realized, which is of practical significance to the construction of land and resources informatization in Yunnan Province.
