【摘要】 地球表层系统最突出的景观标志是土地利用与土地覆被。本文利用“3 S”技术 ,采用三期遥感影像数据 ,经过图像处理、解释、分类后产生三期土地利用 /土地覆被分类图 ,进行叠加分析 ,形成土地利用转移矩阵。再结合土壤、水系、地形等相应数据 ,对 1 978-1 998年三工河流域绿洲区二十年土地转移情况进行空间分析 ,分析各类土地利用类型之间的转变 ,为合理的进行土地利用、规划和决策服务。更多还原

【Abstract】 Landuse and landcover are the most prominent landscape mark on earth’surface.Since 1990,landuse and landcover changes(LUCC)have aroused increasing attention of internation groups and worldwide countries and has been the core program of global environmental change research.Now its research focuses on process,trend,drive forces and entironment appraise.Duty of inspecting of land use change is finished by manual work traditionally,it has many shortcomings such as taking time,hard sledding,costly and inefficient.Today,with the spring up and development of RS(remote sensing)and GIS (geographic information system),it has became possible and been resonated by people to inspect land use change by means of remote sensing. The study area lies in Sangong River Watershed,on the basic of RS,GIS and GPS technologies,the pre-image manipulation was made firstly by using three periods of RS images from 1978 to 1998,involving geometry,registration,enhancement and data fusion and so on,secondly LUCC categorization maps was produced for spatial analysis,finaly LUCC transfer matrix was gotten by overlay,and the types and area change of landuse transfer combining soil,water and terrain data were analyzed .This research is benefit to reasonable landuse,layout and decision of government.更多还原
