A Study Of The Investigating Method Of Country Land Updated In Zhejiang Provice

Along with the rapid social and economic development and the ever-changing environment, land use types, quantity, distribution, status and ownership change more frequently. The accuracy and availability of existing land use data are far from satisfying the needs of the current work. For better planning, and the use and management of land resources, updating land use survey is in urgent need. There are series of problems to be solved in land use updating survey techniques and processes in urgent need, because the technical means of initial detailed investigation are relatively backward, in addition to the asynchronous of map, date and land in annual land changing survey.This study analyses the current situation of the state land utilization first, and describes relative database systems and the GIS system adopted in land management and development. This study chooses Oracle 9i as database management system and Arc GIS as the geographic information management system. This paper analyses the procedure of state land investigation and update, and develops a new technique and method.This study adopts the new technique and method, and the establishes the renewal land utilization database and land management information system, which will provide the evidence for the construction examination and approvement, land development reclamation reorganization national territory resource management, land law enforcement supervision, and also establishes the new management rules and decision method such as "managing land resources by the land imaging".The new technique and method has been adopted in a project - a case of Shangyu, Zhejiang province, which has been approved. This study believes that this new technique and method also might be adopted in other provinces, which should promote the further similar project.
