Research And Application Of Land Use Renewal Investigation Techniques

Use and renewal investigation of land is a technology and management method for a nation to find out quantities, quality, distribution, possession, using actualities, dynamic changing and rule of land. This article has deeply researched the methods and techniques of use and renewal investigation of land combining with the actualities of use and renewal of land in large scale in Jiangsu province, explored the linchpin technologies of use and renewal investigation of land resorting to modern advanced technologies such as global positioning system (GPS), remote system (RS), geographic information system (GIS), database designing and so on, actually had a chosen testing zone applied, summarize technologies, method and technical process suitable to fact in use and renewal investigation of land. Establishing land possession and sort database supported by land administration information system, exploiting module of flux analysis and having module of land sort analyzed basing on database, eventually having the obtained data of use and renewal investigation of land analyzed altogether, providing management of land administration bureau with scientific basis and reference with economic decision of other divisions of government. Meanwhile, the article has discussed the standard of use and renewal investigation of land in large scale, improved application level of 3S technologies in use and renewal investigation of land in large scale, expanded application prospect of 3S technologies. The main contents researched in this article contain:(1) Tallying with production fact, choosing research zone, having the use and renewal investigation of land in progress resorting to 3S technologies and database designing techniques, establishing an integrated producing process of use and renewal investigation of land in large scale;(2) Researching the linchpin technologies in producing process in use and renewal investigation of land, exploring choosing problem and fruit estimating principle of use and renewal investigation of domestic land in large scale nowadays through investigating and testing in two kinds of different scales in a same region;(3) Being under GIS environment, designing exploiting module of flux analysis, having module of land sort analyzed resorting to land administration information system.(4) Having use data of land in testing zone analyzed altogether, obtaining conclusions of analysis estimate, providing scientific principle to using land in reason.
