摘　　要：为查明成都市近30 a来由于城市建设高速发展导致市区土地利用/覆被结构的重大变化,应用成都市1978,1992,2000和2005年4个时相的卫星遥感图像,通过图像处理和信息提取,对其土地利用变化进行了动态监测,建立了不同时期土地利用数据库.利用G IS强大的空间分析功能,提取了成都市28 a间4个时相土地利用的变化信息,对其近28 a间土地利用方式的变化特征进行了定量分析,并从自然因素和人文因素等方面探讨了土地利用变化的驱动机制.研究成果为政府有关部门科学、合理地进行城乡规划与管理决策提供了科学依据.To explore variation in the structure of land use/land cover in Chengdu City due to the rapid development of urban construction in the past approximate 30 years,changes of its land use were dynamically monitored with its Landsat MSS and TM satellite remote sensing images in the years 1978,1992,2000 and 2005,and a land use database for different times was established by the processing of the remote sensing images and the extraction and interpretation of information.With the help of support of GIS（geographic information system） spatial analysis function,the information of land use changes in Chengdu in the recent 28 years was extracted.The characteristics in the structure of its land use changes in the recent 28 years were analyzed quantitatively,and the driving forces of land use changes in Chengdu were discussed from natural and human factors.The research results provides a scientific basis for the relevant departments of the government to improve their acts scientifically and rationally in urban and rural planning,management and decision-making.
