With the strengthening human ’ s impact to the nature , the earth land surface 1s exderiencing profound change land use land cover change has become one of the most important study areas of global changes urbanization and industrialization are major types of land use change in china today , which will certainly have a deep effect on the land use structure and food safety in this paper , multi phases satellite image including corona , tm , etm + data which redresent the information of yixing of 1 966 , 1 984 , 1 992 and 200 1 , respectively were dealt with multi - bands composition , precise rectification , interpretatlon ma ‘ k establishment , computer assistant visual interpretation by the methord of multi 。 phase - sequence comparison and integrated technology of rs and gis vetor maps of land use of 1 984 , 1 992 and 200 1 are attained by interpreting images above . by the data above and the image of corona of 1 966 , vector maps of expanding towns ot yixing city from 1 966 to 2001 are acquired 城市化、工业化已经成为当前我国土地利用变化主要表现形式,它必将对我国的土地利用结构和粮食安全产生深远的影响。本文借助遥感和gis技术,采用多时期连续对比法对fm , etm + pan等多源卫星遥感影像进行土地利用人机交互解译,获得了高精度的宜兴市1984 、 1992 、 2001年三个时期l : 5万土地利用图。利用以上各时期的土地利用数据库并结合1966年corona卫星影像资料建立了1966 、 1984 、 1992和2001年四个时期的城镇建设用地数据库。
