利用1995年TM卫星照片和2005年IKONOS卫星照片作为遥感数据源,阐述了长江上游防护林重点建设区官司河流域10年来土地利用/覆被在数量、结构和空间上的变化特征.明确了土地利用变化的主要类型和变化趋势,并分析了官司河流域土地利用/覆被变化的驱动因子.结果表明:研究区土地利用类型以耕地和林地为主,1995～2005年耕地和农村宅基地面积大幅减少,其余类型都得到一定程度上的增加.各土地利用类型中交通运输用地动态度最大,其次是有林地.在短期内,社会经济进步和宏观政策的制订是影响土地利用变化的主要因素.

This study aims at revealing how land use/cover changed in Guansi River valley which is an important area of protective forests in the upper reaches of Yangtze River. Based on the data of TM remote sensing images in 1995 and IKONOS remote sensing images in 2005, this paper examined the characteristics of the quantities, structure and spatial distribution of LUCC, analyzed the driving forces of the LUCC during the past 10 years. The results showed that the major land covers in the study areas are infield and forestland. During the period of 1995 to 2005, the area of infield and rural housing land decreases markedly and other land use types are increased to some extent. Traffic lands dynamic change index was largest, followed by forestland's. In short term, socioeconomic progress and formulation of the macro policy are major factors on influencing the land use changes.
