【摘要】：土地信息的存储与管理是土地资源规划利用中的重要问题。详尽可靠的土地调查数据是国家经济和社会持续稳定发展的重要基础,是国家管理部门进行土地资源规划的重要依据。我国从1984年开始,对国家各类土地的面积、归属权、空间分布和具体利用情况进行了调查(第一次全国土地调查),但时间已经过去近30年,随着国家的发展,部分数据已经严重失准,且信息化程度低,已经不能满足当前形势下国家管理部门对土地资源进行管理利用的需要。本文在分析了土地信息系统国内外研究现状的基础上,以二调后抚顺农村土地确权登记项目为支撑,以辽宁省抚顺市新抚区为例,利用最新的3S (RS、GIS、GPS)集成技术,以及已有的土地资料和数据,针对传统土地信息保存方法的缺陷问题,首先对建立县级土地资源管理数据库的必要性和可行性进行了分析；其次,本文对县级土地利用数据库的软件、硬件需求进行了分析,并详细设计了该数据库的结构及数据组织和分层；然后,以辽宁省抚顺市新抚区农村土地利用调查等数据为例,开发了辽宁省抚顺市新抚区土地利用数据库。对数据库建设过程中遇到的难题,如土地利用基期数据获取、符号库建立等问题进行了论述,并给出了相应的解决方案,取得了较好的工程应用效果。建库成果实现了对库中数据的存储、查询、分析等土地利用数据库功能,并通过在数据库中加入了土地利用变更图层,存储了土地利用变更情况,方便了对土地利用变更的查询。成果能够为土地管理部门提供分析、决策支持服务,对同类型农村土地信息数据库建设具有一定的参考意义。
[Abstract]:The storage and management of land information is an important problem in land resource planning and utilization. Detailed and reliable land survey data is an important basis for the sustainable and stable development of national economy and society, and it is also an important basis for national management departments to carry out land resource planning. Since 1984, China has investigated the area, belonging rights, spatial distribution and specific utilization of all kinds of land in the country (the first National Land Survey), but nearly 30 years have passed, with the development of the country. Some of the data have been seriously inaccurate, and the degree of information is low, which can no longer meet the needs of the national management departments for the management and utilization of land resources under the current situation. Based on the analysis of the research status of land information system at home and abroad, this paper takes Fushun Rural Land confirmation Registration Project as the support, takes the Xinfu District of Fushun City, Liaoning Province as an example, and makes use of the latest 3s (RS,GIS,GPS) integration technology. As well as the existing land data and data, in view of the defects of the traditional land information preservation methods, first of all, the necessity and feasibility of establishing the county-level land resources management database are analyzed. Secondly, this paper analyzes the software and hardware requirements of the county-level land use database, and designs the structure, data organization and stratification of the database in detail. Then, taking the data of rural land use survey in Xinfu District of Fushun City, Liaoning Province as an example, the land use database of Xinfu District of Fushun City, Liaoning Province was developed. This paper discusses the problems encountered in the process of database construction, such as the acquisition of land use base period data, the establishment of symbol database and so on, and gives the corresponding solutions, and obtains better engineering application results. The results of database construction realize the functions of land use database, such as storing, querying and analyzing the data in the database, and by adding the layer of land use change to the database, the situation of land use change is stored. It is convenient to inquire about the change of land use. The results can provide analysis and decision support services for land management departments, and have certain reference significance for the construction of the same type of rural land information database.
