| 摘 要： | 基于LandsatTM/ETM+、CBERS-02B CCD遥感影像数据,运用RS和GIS技术对二滩库区1995年以来的土地利用/覆盖进行分类研究,对二滩库区13年来的土地利用/覆盖变化情况及驱动力进行了分析。结果表明:1995~2008年间,二滩库区耕地面积明显减少,林地、草地和水域面积明显增加,建设用地面积变化不大;其中林地和草地面积的增加与1998年、1999年两大林业生态工程——天然林资源保护工程、退耕还林(草)工程的相继实施以及二滩水库蓄水后对库区局地气候的调节作用有关。

| Abstract: | Based on Landsat TM/ETM+ and CBERS-02B CCD image-data,the land use/cover of Ertan Reservoir Area since 1995 is classified and studied with RS and GIS technologies;in which the change of the land use/cover of Ertan Reservoir Area in the past 13 years and its driving force are analyzed.The result shows that within a period from 1995 to 2008,the area of cultivated land obviously decreases along with evident increases of the areas of forestland,grassland and water,while the area of construction land occupation ... |
