The Design And Implementation Of The Regularization Supervision System For Land Grant

Construction land is one of the core elements in the process of urbanization development.Timely and accurate grasp of the current utilization of construction land can improve the utilization rate of land resources more efficiently,so as to better coordinate and solve the contradiction between economic development and land supply.But for a long time in our country land related department to the attention of the construction land are mostly stays in the approval process,there are more despise batch after regulation,can't do the specific usage of construction land after the examination and approval timely tracking,and lack of perfect regulation system and technology platform,not around the intuitive view of spatial distribution and block before and after the approval of land utilization,leading to extensive utilization of land and construction land idle phenomenon common inefficient.Therefore,in order to further strengthen the regulation of construction land after the batch job,to verify the actual utilization of urban group for,an urgent need to use the information means to build a set of data warehousing,export,management,batch and not for the data report is used to derive the land of batch for using normalized supervision system,to promote conservation of land resources has practical significance.On the basis of in-depth analysis of the specific business process of land supply and use supervision,the paper designs and realizes the normalization supervision system of land supply and use based on the separation of the front and back end by comprehensively using WebGIS technology,Java back end technology,Vue front-end framework and other mainstream technologies.Based on the detailed analysis and design of the content and complete operation process of the normalization supervision of land supply and use,this paper proposes to carry out the monthly monitoring of land supply and use on the basis of the approval of land acquisition for agricultural conversion and the supply business of construction land,comprehensively investigate the situation of land supply but not supply,supply but not use,and build a set of drawing spot extraction,task distribution and field work Complete business system of investigation and verification,internal audit analysis,report statistics export to final data update and warehousing;based on the periodic remote sensing image data,combined with the vector data of land supply,the corresponding classification standard and extraction process are formulated.Based on the overlay analysis technology and manual interpretation,the automatic extraction of the batch but not provided and the semi-automatic extraction of the supplied but not used spots are realized.On the basis of the detailed requirements design of the system Firstly,the system design based on B/S architecture is completed,the supervision database of land supply and use is established,the centralized and efficient management of land supply and use data is realized,and the periodic dynamic update mechanism and layered mode of land supply and use data are designed and studied;aiming at the problems of large amount of data involved in the system and slow loading of data due to more users' access,a map data caching mechanism based on Vue architecture business data and tile pyramid technology is studied and established;based on the relevant research,the loading method of vector data is improved-a feasible scheme of parsing vector data based on ShapeFile file format in the front-end is designed and implemented,Based on the analysis and research of geometry object data format,the front-end technology is used to realize the real-time rendering and rendering of image spots,which greatly improves the system performance.The normalization supervision system of land supply and use established in this paper has achieved the purpose of mastering the state of land supply and use in time and accurately and managing and applying the data of land supply and use in batch but not in supply and not in use effectively.At the same time,it has practical significance to further digest and activate the stock land,strengthen the effective supply of construction land and promote the structural reform of supply side.
