In, the Ministry of Land and Resources made a major adjustment to the national land classification system. According to the requirements of the Ministry of Land and Resources, a unified new classification system will be adopted for urban and rural land nationwide, and the land and resources departments will implement unified management of urban and rural land nationwide. However, from the current cadastral management system in China, there is a phenomenon that urban land and rural land are managed separately. The establishment of urban land registration system is microscopic.

Cadastral map is managed through cadastral survey and registration, and macroscopically through the summary statistics of urban parcel accounts; Rural land is mainly 1:

Supported by 10,000 maps of land use status, the management is updated through the annual change survey. Relying on this management system, urban cadastral management information system and rural cadastral information system (land use status management+collective land ownership registration) have been formed in the construction of cadastral management information system for many years. The two systems are both connected and separated, which leads to the inability to connect, overlap or open skylights in the urban-rural fringe, which occurs in most places.

The change of land use status map can't keep up with the spread of urban construction, and after the implementation of the new land classification, strictly speaking, the year-end change data of two sets of urban and rural management information systems have to be manually nested every year to get the annual land use status change data, which can't fully reflect the high efficiency brought by informationization.

Judging from the existing cadastral management information system software, most of them are single management software, that is, rural cadastral management is separated from urban cadastral management and has independent systems and data, while rural and urban cadastral management is managed by land and resources management departments. In many places, especially in the urban-rural fringe, the boundary between urban and rural areas is not obvious. With the acceleration of the process of urban-rural integration, it brings a lot of inconvenience to land registration, statistics, summary and comprehensive analysis in land management, and is not conducive to the update of basic databases such as land use planning, construction land management, mineral resources management and cadastral data. From the current urban cadastral management and rural land use status management model, there are many similarities or similarities in ownership management, land statistics and analysis, but urban cadastral management pays more attention to ownership management, while in urban land use status management and land statistics, the current rural land use status management model is more reasonable and can better reflect the urban land use situation. In many years of informatization practice, the author deeply realized that it is very necessary to establish a cadastral management information system integrating urban and rural areas after the implementation of the new land classification system. Unify the software, data structure and organization management mode of urban and rural cadastral management information system to ensure the necessary data foundation for land use control.

Second, the basic idea and feasibility of establishing urban-rural integrated cadastral management information system

(A) the basic idea

Firstly, the concept of urban-rural integrated cadastral management information system described in this paper is defined, which is put forward from the user application level, that is, it can help cadastral managers to realize the unified management of urban and rural cadastre in the same way in one system and under the same operation interface, and realize the "seamless" integrated management of rural land and urban land according to the business needs of land use management and property rights and property registration management.

Feasibility of urban-rural integrated cadastre

Need to consider the possibility of realizing management information system. In China, the basic unit of urban land registration is parcel land, and the basic unit of rural collective land registration is villagers' autonomous groups.
