An Study On Grid Institution Of Land And Resources Informatization Construction

Land and resources is the important material base of human being survival and development,is the basic backing of the national economy and the people's livelihood."looked in the space,looks up on the ground,monitored on-line" is our country land resources management basic method be proposed By "the golden earth project".Land resources information is the only way to monitor on-line.For the sake of better fulfilling its land and resources management departments of land resources planning,management,protection and rational use of the government's management functions,accomplishes the land resources management modernization,raises the land resources administration level,we must realize the land resources informationization.This thesis developes according to the clue from theory to practice,from practice to theory,in order to fundamentally change the backward aspect of the land resource cruising data management,on the base of remote sensing,telemetering and geographic information system (GIS),Establishes the complete land resources management system,make the best of existing data and the introduction of new technology,new methods for data updates,so that land and resources data is a potential and real accuracy,To achieve information sharing,implementation of the management of land resources information management and monitoring.A Case Study of Shapingba District in Chongqing,Proposed for the first time establish the perfect griding management model,establishes the entire district(380km~2)"the grid management" system.Establishes the entire district "four charts to unite" the control system and the system design.The foundation database's construction namely take 1:10000 inner border and 1km~2 as one unit,The whole district Shapingba is divided into a number of grid.To has the region which many kinds of scale graphs simultaneously exist to implement the layered management,the document naming differentiates in the database by the scale code,according to the needs of users to called the different data files,to achieve of display in different scales graphics,on the basis of taking full advantage of existing operational systems,to share Land management planning,use of(land transfer),registration,approval, monitoring law enforcement(GPS Monitoring),statistics,internal information,realizes the land resources informationization construction dynamic management。The following are the main research contents of the dissertation:Part one is perface,include the background of the article and the significance of study,the target,content,method of study.Part two is introduce the basis of the theory and methods of Grid system,including analysis of the grid system,the progress of research and theoretical synthesis and the conversion of geographical coordinates.Part three:The establishment ideas District Shapingba Land and Resources unit grid.On the base of analysising the geography general situation and the present situation of land resource information in District Shapmgba,aimed at which appears in view of the grid system management, has formulated the geography grid division principle and the method.。Part four,designing and achieving land resources information system's which based on the grid system,Part five:System function appraisalPart six:Application prospect and forecast。Summing up this article prime task and research results,merit and insufficienc.Proposed that this article innovation spot lies in the grid system application applies for the land resources informationization construction the first time,and carries on the forecast to the following work.
