The Research Of Urban And Rural Integrative Land Survey Data Organization

As the fast development of economy in our country, the relationship between urban and rural districts has been growing closer and closer, urban and rural integrative becomes an important trend for the future construction and development for our country. Recently published policy demonstrates the strategy position of urban and rural integrative, and in the process of urban and rural integrative construction, land management plays an important pole.At the beginning of the establishment of land information system in our country, for adapting to the great difference between urban and rural districts in that period, government adopted the mode of separately treatment, establishing the urban cadastre database and country land use database. However, problems occur in present condition, such as spatial separation between these two systems, inconvenience caused by different coding system, overlap in the statistics, the low efficiency in the use of the two systems and trouble in the system updating, expansion and management.This research analyzes the existing problem, referring to the standard and regulation which are being used now, and with the help of land management theory, geographic information technology and database theory, this paper discusses the idea of how to organize urban and rural integrative land survey zoning hierarchy, proposes a detailed method of land survey zoning, probes a modified urban and rural integrative coding system, and in this research, a new ER modeling based method of designing urban and rural integrative land survey database is proposed, with an example of Enshi district in Hubei province.The innovation of this study includes:(1) Based on the urban and rural integrative land survey hierarchy, propose an integrative partition method of land survey zoning; (2) Design a different urban and rural integrative land survey coding system, which adds an new code column called characteristic code;(3) Analyze the old urban and rural separation database, compare the different data models between urban and rural separation and integrative , demonstrate the advantage of urban and rural integrative in data organization;(4) Propose a new data model of urban and rural integrative land survey, which is based on ER model and refer to the Object-Oriented method.
