The remote seosjng image processing technology, analysis method and feasible conclusion handed in this paper will have some direct and reference value in engineering practice on utilizating resource investigation. Keywords:1and utilizating resource investigation:high resolution:Satellite remote sensing image;accurate rectification;image enhancement;image fusion ;image fusion;image interpretation 1 土地利用资源调查 1.1 背景 人类面临着尖锐的人口大幅度增长、非再生资源趋向枯竭和生态环境不断恶化的巨大压力等问题。保护土地资源和实施可持续发展战略是全面建设小康社会的重要保障，卫星遥感技术的兴起与发展使人们有可能从太空的高
