| 摘 要： | "3S"技术在国土部门中应用以来,极大地推动了土地利用变更调查技术的发展,由于"3S"技术各有侧重,加之目前的土地利用变更调查具有变更速度快、数据精度要求高等特点,"3S"技术集成应用成为必要和趋势。"3S"集成模式多样化,在土地利用变更调查中要根据土地利用类型变化的速度、数量以及经济条件等因素选择相适应的集成模式,实现高效率、高质量的土地利用变更调查。

| Abstract: | With the application of "3S"technology to country department,land use changes survey is greatly developed.Because "3S" technology has different emphases,additionally,land use change survey requires higher precision data,and at the same time the land changes more frequently,so "3S" technology integration becomes necessary and tendency."3S" integration has different mode,and which mode is appropriate lies on the land use change frequency,amount and economy and so on,which can help you accomplish land use change survey with lowest cost and shortest time. |
