摘要
土地资源是人类生存的重要基础,摸清土地资源现状及时掌握土地变化信息是进行土地利用总体规划和国土资源宏观决策的依据.目前广泛采用的调查方法受很多因素影响,很难获取变化图斑的准确空间位置.RS,GIS和GPS技术集成应用近年来得到了迅速发展,3S技术在土地资源管理的应用是一个重要的研究方向.在研究传统土地利用变更调查方法中存在问题的基础上,结合3S技术特点和土地利用现状探讨了基于3S技术的土地利用变更调查的技术路线.
Land resources are essential to human survival. Ascertaining the actual situation of land resources and information of land change, which is a basis for overall planning of land use and macroscopic decision making on land resources. Now, the widely used methods of survey are affected by a number of factors, it is difficult to ascertain the exact space location of changed map spot. In recent years, the integration of RS, GIS and GPS （3S） has become an important field in the land resource administration. The author based on the traditional analysis methods of land - use changes, unified the 3S technology characteristic and the present land utilization situation to discussed landuse change investigation, which based on the 3S technical route.
