摘要
本研究首先把遥感数据作为一种信息源,提取地表环境各类地学宏观信息,如覆盖类型及变化、土壤类型、植被生物量、水土流失状况等;然后进行全面、系统、真实的分析,为水土流失的监测、优化管理、规划发展提供完整的决策依据。
This paper use the remote sensing data as an information source,extract the surface environment to study various types of macro information,such as cover type and changes in soil type,vegetation biomass,soil erosion status;and then conduct a comprehensive,systematic and real analysis,we use the analysis as the basis of optimal management,planning and development.
