| Abstract: | The combination of Remote Sensing(RS), Global Position System(GPS), Graphical Information System(GIS),which are characteristic of celerity, precision and dynamic, can find the eco enviromental condition of the research area, and develop the eco environmental base survey database with high precision, which available the scientific direction for the government's macro decision making and layout.The paper ,as an example of the assumed project of "the Synthetic Survey and Evaluation of Eco environment with Remote Sensing in Minjiang Middle and Upper Valley" of National Theme 863 308,"the Golden Eye Action", discusses that the application of utilizing the "3S" technology(RS?GPS and GIS)to instruct setting down the policy of Changing Cultivation into Tree Planting and monitoring the eco environment. The precision of calculating surface area can meet the demand of 2 rank resources survey of our country. |
