System Construction And Practice Of Land Supervision Information Platform

Since the 21 st century,we are facing an increasingly severe situation of land resource.Land resource is the solid foundation for the high speed economic growth,as the critical shortage and irrational exploitation of it seriously restrict the economic development.In recent years,China is gradually improving relative rules and regulations,including the strictest land administration system,cultivated land protection system,and economical and intensive system in the world.And to actually put the “Three Strictest Systems” into effect,land supervision system is an important measure for central government.Land supervision system is to protect the land resources,guarantee the inventory of cultivated land and prime farmland,control the scale of the construction land,and make sure economical and intensive utilization of land.As an important way to make the management more efficiency,the decisions more scientific,the governmental affairs more transparent and legitimate,advanced technologies and information technique are inevitable choices for land supervision work with this new situation.The state land supervision institution must make full use of modern information technology,the present situation of land use dynamic monitoring technology,and information technology to establish an information platform for the land use and management situation monitoring.And finally this platform will expand as a land supervision information system with the function of access information,response rapidly;evidence investigation,immediate feedback,and handling supervise.Based on the establishment of the land supervision information platform of the Xi 'an Bureau of State Land Supervision,key issues in real establishment and application were discussed in this thesis.And with the study of build and application of the land supervision information platform,this research goal is to realize the integration and sharing of data,the establishment of land supervision business information system,and the formation of land supervision management network model which is scientific,standard,and with high efficiency.Considering the requirement of state land supervision business,the research mentality is based on the data center to build up the land supervision business information system which covered the all relative business processes.In the aspect of technology,the practical,advanced and mature technologies have priority;in the aspect of information security,considering the confidentiality requirements of state land supervision business information and the transmission rate,the establishment of private network that equipped with encoder for land supervision and the data exchange system and video conference system are necessary;in the aspect of information utilization,interconnection and fast transportation of the information is most important;and for the expansion of system,the expansibility and perspective means more possibility of offering interfaces for information exhibition,monitoring,and conducting;for the standard construction,the study of fieldwork supervision technologies standard and the information collection processing standard may offer the technical references for the construction of the land supervision system.Under the guide of system theory and control theory,the research methodology is making use modern information technology and land use situation dynamic monitoring technology to build an Integrated Application System.The technologies mentioned above mainly include 3S technologies(such as remote sensing and telemetry,global positioning,geographic information system),WebGIS network service,database and other monitoring technologies.And the Integrated Application System overlays multiple graphic levels(such as remote sensing images for dynamic monitoring,overall plan for land utilization and present use of land use).This system integrates materials from multiple levels and multipleperspectives(for example,the exam and verification,exam on the spot,reports from the masses,medium information for the examination and prove for the construction land).And this Integrated Application System help supervising over the act of government in cultivated land protection,land use right grant,land supply,land use,and law enforcement supervision.The main research content and new achievement were as follows:(1)Proposed the general strategy for the establishment of land supervision information platform,and initially build up the prototype of the land supervision information platform,land supervision bureau business system,integrated automated office system.(2)Established the general framework and four levels of the land supervision information platform.Four levels of the land supervision information platform include business level,application level,data level and network level.The business level is the land supervision business information system,which include the land supervision remote sensing discovery system,routine supervision system,auditing and monitoring system,and special project supervision system.The application system runs business processes by combining the land supervision official integration system,including land supervision long distance video system,non-secret-involved land supervision file transmission system.The main part of the data level is the data center construction,which is based on the data center of ministry of land and resources to build up the data exchange system for the branch of land supervision bureau and realize the basic business data exchange and sharing.The network level is to realize the connection to the backbone network of ministry of land and resources,to keep the physical isolation between internal and external network of each land supervision branch,which could guarantee the data sharing and exchange,meanwhile emphasize the network security.(3)Designed and developed the land supervision remote sensing discovery system.This system is based on the satellite images,aerial photographs,and unmanned aerial vehicle data to supervise and discover land use anomalies.Through the collecting of medium information,mass reports,and leading instructions to realize the information classify,process and finally summary analysis.In this system,remote sensing data and GIS data of this area are unified as“background database”,and keep being continuous updating.(4)Designed and developed the land supervision auditing and supervision system,routine supervision system,special project system,integrated automated office system and so on,and these systems improved the information platform architecture.This research also realized the integrated utilization of land supervision information in important areas;completed the unified administration,analysis,decision of supervision business data,and online scheduling of supervision tasks;completed data exchange,sharing and remote procedure call with ministry data center system and provincial data center,which made the land supervision process become more scientific and efficient.Moreover,the land supervision way has changed from a manual work into a modern informational land supervision system.This research has been implemented in Xi 'an Bureau of State Land Supervision successfully,and shown a satisfactory performance.
