Study On The Establishment Of Land-use Change Survey Database And Information System In The County (City)

It's been more than 10 years from 1990 to now, though the land-use change survey has been done once a year from 1996. With the socialized, the economical rapid development, the urbanization, the industrialization advancement speeding up. Every year land-use change survey cannot accurately reflect the land-use change situation, which affects the decision of government. It's imperative that the graphic document, the data are all consistent by the advanced technical method to carry on the land-use survey with the present situation.The combination of 3S technology is the important direction of space information technology in current. 3S technology refer to the Remote Sensing (RS),Geographic information system (GIS),Global position system. In the land-use survey , RS can provided the reliable data pool to GIS. GPS can look up the land parcel rapidly corresponding in the database in order to realize the land parcel and renew the date. But GIS can analyze and apply the information Exhaustively to the date pool provided by RS. 3S technology to observe system space information obtain,store ,manage,upgrade,analyse and three that use heavy to support technology right at present, the studying and using beginning to move towards being integrated of 3S in the world.Generally speaking, RS and GPS offer the high-quality space data for GIS, but GIS is the platform dealing with these data synthetically, and instruct RS and data of GPS to be gathered conversely ,they are an organic whole.This text directs against the question that the traditional land utilizes the change to investigate that exist in the method .Based on the analysis of this text direct against the question that the additional land utilizes the change to investigate that exist in the method, taking the Bole city as the example ,combining 3S technological characteristic and land utilize current situation probe into taking GIS as the core 3S technology utilize change application of the investigation in land and the storage of large numbers of spatial data, Concrete to explain based on 3S technology land utilize technological route and 3S technology that change investigate utilize. Combine 3S technological characteristic and land utilize current situation probe into taking GIS as the core 3S technology utilize change application of the investigation in land, Concrete to explain based on 3S technology land utilize technological route and 3S technology that change investigate utilize and alter and investigate every technology of link in land.At the same time , this paper regards systematic scientific theory as guidelines, and uses computer science , land resource management and GIS (Geographical Information System , geographical information system ) such multi-disciplinary knowledge as technology ,etc. Synthetically, use the theory and method of the soft project, through utilizing analysis of data management business and user's needs to the land, carrying on the land utilizes the change to investigate the overall design of the management information system and design of storehouse of data, have set up systematic function frame and land incorporating space database and attribute database into an organic whole and utilized the database. On this basis, regard MAPGIS as the platform, developing the land based on GIS utilizes the change to investigate the management information system. The system has met users to the data analysis of the map and need that deal with as for the function, realized the land utilizes automation of data management business at the same time, improved office efficiency greatly , have made the remarkable economic benefits and social benefit. Experience in such aspects as soft hardware disposition, technological method and system scheme adopted in systematic construction, have certain value to popularize and reference meaning too in the construction of the management information system of book of ground of our country in the future.Have realized tentatively that the land based on client/ server utilizes the change to investigate the information system.
