A Study Of Integrating Method Of The "Three Database" Of Rural Collective Land

With the development of computer, database and network technology, the management of the national land data has realized the informatization, which is avoiding the shortage of original paper management. The work of rural collective land confirmation, registration and certification is pushing on. All parts of our country have established the “three database”,namely rural collective land ownership database, rural collective constructive land use right database, rural collective land contract and management right database in order to manage the collective land. But with the constant flow of various land of rural collective land results in the land ownership boundaries unclarity, which leads to the conflicts in rural areas aggravating. There is an urgent need for unified management of various types of rural land to clarify the boundaries, which protect the legitimate rights and interests of land obligee.Therefore, this paper attempts to integrate the “three database”of rural collective land.During the study of method for the “three database” of rural collective land, this paper firstly studied and analyzed on rural collective land ownership, use rights and the corresponding database, which laid the foundation of integration theory of the “three database”. Secondly, this paper discussed and designed the meaning, organization and management, property data and the subject of right information of spatial data in the “three database”. Finally, combining with specific data the integration of the “three database” was accomplished, which achieved a query of graph and properties. At the same time, this paper also analyzed practical application of the “three database”. In this paper, the main works are as follows:(1) Based on the rural collective land right,this paper analyzed the purpose, mathematical foundation, database content and land ownership Investigation of the “three database”: rural collective land ownership database, rural collective constructive land use right database, rural collective land contract and management right database.(2) Combining land ownership and land use,this paper divided land type patches of rural collective land into: a parcel of constructive land use right, a parcel of agricultural land use right, a parcel of land type patches and explained the meaning of every part, which laid the theoretical foundation of spatial data organization of the “three database”.(3) Based on the existing database of rural collective land, this paper designed of the organization and management way of spatial data of the “three database” and attribute structure of each layer, which made the “three database” combine graphics and attributes. At the same time, in order to achieve the purpose of land ownership, this paper summarized the subject of right in the process of land ownership and designed their information table, which linked land to the subject of right. All above are the “three database” practical needs.(4) With the use of personal database of the Arc GIS software, combining the project data of Yuyang district in Yulin, this paper integrated spatial data of the database and achieved a query of attribute information of, so that the graph and attribute case was accordant.(5) This paper analyzed the application of the “three database” from the registration of immovable property, the confirmation, registration and certification of land, the delimitation of basic farmland, the survey and demarcation of land this four aspects.The achievement of the “three database” realized the unified organization and management of the various types of rural collective land and houses, avoided the aggravating conflicts caused by the phenomenon of unclear boundaries during the rural land transfer process, protected all the collective farmers as well as farmers’ land property rights from violating and provided data support for the registration of immovable property.
