摘　　要：土地卫片执法检查是政府实施土地严格管理的重要手段。本文以绵阳市2009年度遥感土地执法检查为例,选用2008年和2009年两个时相的中巴资源卫星02B遥感图像作为信息源,对3G与3S集成技术在土地利用执法检查中应用方法进行了研究。该方法利用RS获取土地利用变化信息,利用VRS-GPS技术采集变化图斑空间与属性特征信息,利用3G通信技术进行现场数据传输,利用GIS技术进行数据处理、空间分析和可视化管理输出。实践表明:3G与3S集成技术是一项基于3G网络的RS、GPS、GIS于一体的土地利用执法检查新技术,具有实时监测、精准定位、无线传输、快速分析处理和可视化输出等特点;该方法的应用不仅提高了土地利用执法监测精度和工作效率,而且降低了工作成本,实现了核查成果可视化网络管理,为违法用地处理科学决策提供服务。The law enforcement inspection of land satellite image is an important means for the government to implement the strict land management.Taking the 2009 law-enforcement inspection of land satellite image in Mianyang City as an example,we selected the 02B CBERS remote sensing image of 2009 and 2010 as an information source to study the application methods of the 3G and 3S technology in law-enforcement inspection of land satellite image.We obtained land-use change information using RS,gathered spatial and attribute information of land-use change plots by VRS-GPS,transmitted the site data by 3G communications technology,and used GIS technology for data processing,spatial analysis and visualization management output.The results showed that： it is feasible to gain the land use change information,identify the monitoring spot,survey the spots,transmit wirelessly the data,compile the maps and construct the database based on 3G and 3S integration technology.It has the characteristics of real time observation,accurate positioning,wireless transmission,rapid analysis,visualization output and it has good application prospect.It can provide timely the land-use change monitoring and accurate measurement information,and provide scientific services for decision-making to deal with the illegal land-use.
