基于3S的土地利用现状常态化监测调查技术体系探索

Research on the Constant Monitoring and Investigating Technical System of Land Use Status Based on 3S Technology

以南昌市为试点区域,采用3S技术建立土地利用现状常态化调查监测技术体系,基于卫星遥感获取区域内高分辨率影像,利用无人机进行重点区域获取航摄影像,CORS系统获取点位坐标,高效准确地分析区域范围内土地利用变化情况,探索土地利用调查监测常态化、规范化新模式,充分发挥3S技术在土地资源管理业务中的应用。

Taking Nanchang City as the pilot area,we adopt 3S technology to establish the constant monitoring and investigating technical system of land use status.By acquiring high-resolution images based on satellite remote sensing,supplementary aerial photos in key areas by UAV,and precise point coordinates by CORS system,We analyze the land use change effectively and accurately,explore the constant monitoring and investigating of land use,standardize the new mode,and improve the application of 3S technology on land resource management.
