针对城乡土地权属登记工作的基本需求,重点研究土地资源利用变更调查中3S技术的应用,结合某土地资源调查项目案例,从基于遥感(Remote Sensing,RS)技术获取变更图像、基于全球定系统(Global Posi-tioning System,GPS)进行空间定位、基于地理信息系统(Geographic Information System,GIS)实现建库管理3个方面对3S技术展开分析,并总结了项目土地资源利用的变更幅度、速度.研究表明:合理应用3S技术,能够客观掌握土地利用动态变化情况,为土地管理和土地规划提供可靠依据.
Application Analysis of 3S Technology in Land Resource Utilization Change Investigation
In response to the basic needs of urban and rural land ownership registration work,this paper focuses on the application of 3S technology in land resource utilization change investigation.Combining with a case study of a land resource investigation project,this paper analyzes the changes in land resource utilization from three aspects:obtaining change images based on Remote Sensing(RS)technology,spatial positioning based on Global Position-ing System(GPS)technology,and database management based on Geographic Information System(GIS)technol-ogy.and summarizes the magnitude and speed of land resource utilization changes in the project.The research re-sults indicate that the rational application of 3S technology can objectively grasp the dynamic changes in land use and provide reliable basis for land management and planning.
