三峡库区湖北片土地利用动态变化研究

Research of dynamic changes of land use in Three Gorges Reservoir region

根据1986年和2000年2期卫星影像,运用"3S"技术对三峡库区湖北境内的巴东、秭归、兴山和宜昌4县1986年和2000年的土地利用状况进行了动态监测。全面分析了土地利用的变化情况,揭示了该地区各类土地利用类型数量变化的幅度、速度和区域差异,阐明了该地区土地利用变化的区域特点。成果可为三峡库区的水土保持和土地可持续利用提供有效的决策支持。

Based on the satellite images in 1986 and 2000,the land use changes of the four counties of Hubei province in the Three Gorges Reservoir region, i.e., Badong county, Zigui county, Xingshan county and Yichang county, were monitored. Furthermore, the land use change trend is analyzed comprehensively. The change extent, speed and regional difference of the different kinds of land use are calculated. The regional change character of the land use is clarified. These results can make effective supports to land sustainable use for TGP reservoir area.
