Application of “3S” Technology in Land Resource Management

Abstract

Land resource management is one of the most important ways to deal with the relationship between land resource and human being to improve land use efficiency and gain more benefits. “3S” technology refers to remote sensing (RS), global positioning system (GPS) and geological information system (GIS). “3S” technology is widely used in different fields generally as an excellent method and it has advantages to exploit in land resource management. Now as the population grows, the conflict between land resource and mankind extrudes with global resource shortage. The effort using “3S” cannot be ignored. This article explains the definition and ability of “3S” technology and analyze the application of “3S” in the Investigation of land resource, land environment dynamic monitoring, land evaluation, land consolidation and land planning. The author concludes the utilization of “3S” technology in land resource management and looks forward its development in the future from different perspectives. Informatization, intelligent and integration are three directions “3S” will make progress. This article takes some examples to illustrate how to help “3S” technology step forward in the future. Through these ways, the optimized “3S” technology has ability to overcome disadvantages and build up new use of the way. So the efficiency of land resource management will be improved obviously to achieve the sustainable use goal of land resource.
