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.
