Study On Key Technologies To Construct Land Use Planning Database In Jinan

With the pushing of reform and opening and the increasingly development of economy,China’s human-land conflict has become more and more intense and serious. Treasuring andemploying every inch land is of significant meaningful to our country’s scientificdevelopment and sustainable development. To meet the demand of development, the secondnational land use survey was organized in2007, which made a thorough investigation of landuse around China. In order to make a further reasonable arrangement on land use types andoptimize and upgrade industrial structure, thestate councilorganized the new round of generalland use planning at all levels. At the same time, as part of the project “The Digital LandEngineering”, the construction of land use databases at levels of county and city has beenstarted, which stores planning schemes and data, and offers service to land-relateddepartments.Based on the author’s experience on database construction, the research firstly designsthe planning database structure and data organization mode according to an analysis of landmanagement departments’ demands. Secondly, several critical technology of databaseconstruction were introduced and discussed, including transfer method between two commondata types, edge-match method of framing space data, zooming and editing method of thedatabase, map generalization methods and the integration of mapping and databaseconstruction. Researches on the key technologies can be the foundation for the database’sconstruction. Finally, the study gives opinions on the problem of the disability for properraster map’s output, and raises the integration model of mapping and database construction.This thesis includes six chapters. In the first one, the background of the construction ofland use planning, research overview and the aims and main contents are introduced. Thesecond part comes to be the description of related theories and methods including land useplanning, planning database and characteristics of GIS software which are commonly usednowadays. The related work of preparation and design are organized in the third chapter,contents including choice on the software are also mentioned. The forth chapter discusses the five critical technologies mentioned above, and gives the optimized methods in the projectaccording to its unique demands. Jinan is taken as the study case in the fifth chapter, whichdiscusses the solving methods in the construction processing. The last part is conclusion andprospect.In summary，Based on the construction of land use planning database, the paper solvesthe problems that exist in the database construction, optimizing the scheme of buildingwarehouse, further basis for national economic development strategy to provide support。Andalsoprovide information support for the development and utilization of land resourcesplanning and decision-making basis.
