Suburban Towns Hollow Village Information System Research And Development Based On WebGIS

The emergence of "hollow village" has a great impact on the construction of new countryside in our country.Carry out a comprehensive renovation of the hollow villages is an important measure to protect the cultivated land,strengthen the new rural economic construction and balance the development of urban and rural areas.The hollow village digital construction is the important components of the comprehensive renovation project of the hollow village,which will help to improve the traditional management mode of the village,improve the work efficiency and increase the village vitality.Therefore,the establishment of a village information system for the hollow village comprehensive renovation is of great significance.This system uses the GIS technology,database technology combined with web technology and based on the B/S mode to construct a Suburban towns hollow village information system.Through the system can realize the village information visualization analysis and management,while providing network publishing function for the village products,village characteristics,village tourism and other information.The main research work and research results of this thesis are as follows:(1)Through research and investigation on the hollow village in urban suburbs,the demand analysis of the hollow village information system in urban suburbs is carried out,and the system function modules are divided.Include:Resident information management module,natural gas management module,information release module,public opinion collection module,Residential rental module,agricultural product transaction module,village tourism module,BBS communication module.At the same time,the functions of each subsystem module are designed in detail.(2)Through the study of functional modules,using B/S mode,combined with GIS technology and Web technology,built a five-tier architecture based on WebGIS:Data layer,logical layer,service layer,application layer and presentation layer.Data layer:the spatial data,attribute data,relational data used in the operation of the system;Logic layer:to achieve the system function module used by the business logic method;Service layer:the use of network GIS operations used by the map data services;Application layer:the functional implementation of each sub-module of the system;Presentation layer:simple and friendly interface.(3)According to the function analysis of the system,the database structure is designed,and the entity relationship diagram of each subsystem module is drawn and the database form is designed.At the same time,according to different data types,the use of SQL Server to store relational data,and spatial data management and storage using ArcSDE + SQL Server to complete.
