The Construction Of Count Level Land Use Status Information System Based On MAPGIS

Our country has developed land use status investigation since 1984 which undergo over 10 years, and achieved a lot of materials about land use and authority from parcel of land to village, to county, to city, even to whole nation, that are very full and accurate; formed different scale land use status graph from 1:10000 to 1:1000000 and relative data. But these valuable materials are still stored in boxes and cabinets in paper, it limits management and transmit analysis of data; renewal and use of date. At the same time, it affects seriously security and reliability of these data. In recent years, Territory Resources Department has accelerated the pace of study of territory resources information, and achieved tremendous achievement. But the construction of land use status information system is based on land use status investigation in 1990, which was time-consuming in time, national in range, uneven in data quality, so the construction of land use status information system confronts many difficulties. On this fact, this paper selected the Count of Tunliu in Shanxi Province as research zone, the author explored application study on the information construction of territory resources that is fit for condition of our country.Based on "Technology Regulations in Land Use Status Database Construction at County or City Level " and land use status achievement, according to data of 1990 and data of 2000, we established initial database and renewable database separately. On the basis of study of theory and method on land use status information system construction, by material collection, graph scanning, data gather, graph edition, data processing, database establishment, system improvement, system probation and so on, we established property database based on Visual FoxPro, and established land use status information system ultimately.By experiment in land resource department of Tunliu, it has been proved that land use information system is highly automatic ,stable to run and simple to operation.The construction of Land use status information system improves the accuracy and the trends of times of land use information, it automatically stores, manages, researches, inquires, counts, analyzes, renews and defends land use status graph which is digital, solves the problem of the renewal of land use status graph and data. It provides not only modern technology means for everyday professional work in county level land management department, but also basic data and scientific basis for land use renewable investigation,dynamic monitoring, land use totality planning. On the other hand, it lays a foundation for the establishment of cropland transform system, land exploitation and readjustment, approvable management system of construction project used land, management system of rural land register. It also provides technology services for land use dynamic monitoring, approval and management of construction land. By the construction of system, it solves the problem of land use status investigation in 1990, such as time-consurming, Wide in range, different technology level, uneven data quality and so on; it also provides the renewable method of land use status information. In the end, the author raised quality control of land use status information source, organization and coordination of system, renewable standard of system .
