基于遥感与GIS土地利用/覆盖动态监测及驱动力分析

以TM和CBERS-02图像为遥感数据源,在遥感和地理信息系统技术的支持下,对2000～2004年四川省土地利用状况进行了定量的变化分析;并对研究区4年间的土地利用/覆盖状况及其动态变化在时间序列和空间序列上加以分析,阐明这种变化的外在表象,即林地、城镇用地、水域的增加和耕地、草地、未利用土地的减少;同时,探讨了这种变化的内在驱动力主要为人口增长、工业发展、政策导向等。研究成果为准确分析四川省土地利用状况和环境变化趋势提供了有效的数据支持,为国土资源的可持续土地利用提供决策依据。

The Dynamic Monitoring of Land Use/Cover Change and Its Driving Forces Based on Remote Sensing and GIS

According to the image of TM and CBERS-02, the paper quantificational analyzes the changes of land use status in Sichuan province during the period of 2000-2004 based on the techniques RS and GIS, and analyzes the land use/cover status and dynamic changes during four years on temporal and spatial series. The explanation is given about these facial phenomena, i.e. the increase of the land use of woodland area, construction area and water area, and the decrease of the land use of plow land area, meadow area and wasteland area. Meanwhile, the paper discusses the inner driving forces, i.e. the population increase, the development of industry and policy guiding etc. The study production provides the effective data for reasonably and accurately analyzing the status of land use and the trend of environment changes, and provides the decision to the sustainable utilization of the land resources.
