摘要
通过对2000年、2009年多源遥感影像的土地利用/覆盖专题解译,对西霞院水库工程区土地利用/覆盖时空动态变化特征进行了分析。结果表明:西霞院水库工程建设前后的近10年期间,区域土地利用类型变化比较明显的是农田及水库坑塘,其中水库坑塘的动态变化率达14.5%,与建设前相比,水库坑塘面积增加幅度较大,而农田呈减少的变化特征。区域土地利用/覆盖变化是自然环境条件和人为因素相互作用、共同约束的结果,其中水利工程建设是土地利用/覆盖变化的直接驱动力,人口增加和城镇化是重要的驱动因素,自然因子对于区域土地利用格局演变也起到一定作用。
Through multi-source remote sensing images interpretation of 2000 and 2009 with remote sensing(RS) and geographic information systems(GIS) spatial information technology,the paper analyzes the dynamic characteristics of regional land use/cover around Xixiayuan Reservoir.The results show that during 10 years of Xixiayuan Reservoir construction,the land use/cover structure of farmland and reservoir have been significantly changed.The water surface area extensively increased,while farmland area decreased compared with related area before the reservoir construction.During the period,regional dynamics index of reservoir reached 14.51%.According to the driving forces of the land use/cover pattern change,the natural and artificial factors together led to the changes.Among which,the reservoir construction is the direct driving force,population growth and urbanization are important driving forces,and natural factors,such as temperature and precipitation also play some important roles.
