A study on remote sensing key technologies of national monitoring resource, ecological and environment

In recent years, many countries have built national remote sensing monitor systems of land use and land cover change. These systems could acquire the dynamic information of land use change information. Today, the construction of united national resource, ecological and environment system requests people deploy remote sensing monitor task within one framework about resource, ecological and environment based on the actual systems. The project will be aimed to the national key ecological and environment regions and provide basic and stratagem information to supply national resource, ecological and environment improvement. 2002, CMLR began remote sensing monitor of resources, ecological and environment in Beijing surrounding area. The destination is to contrast and analyze the environment actuality and change status in recent ten years. In the mean time, the project had located the main sand sources, sand transfer region and barrier regions of Asia sandstorm. Some key technologies had been discussed in this paper. Particularly, this study uses a great deal of spaces to expatiate some urgent problems and the resolution during the national resource, ecological and environment remote sensing monitoring.
