| Abstract: | In Integration with the main information from the RS, technically supported by Geographic Information System and Global Position System, the RS information system of county-grade ecosystem and environmen of agriculture resources is constructed by years' division of agriculture resources in the county. Utilizing the RS source information of ETM, eight kinds of land are divided into. In a case of Xinjinghe drainage area, the information system is supplied to analyze and evaluate the ecological environment, and scientific decision is presented. |
