基于遥感技术的城市化进程中南京浦口区的土地利用变化

The Land Use Change Based on the Technology of Remote Sensing with the Urbanization in Pukou District,Nanjing City

揭示城市郊区的土地利用变化规律对于城市化过程中如何正确规划和合理利用有限的土地资源具有重大的意义。利用1988、2000和2006年的遥感影像对南京市浦口区进行了土地利用分类，并把2000年和2006年的分类矢量图层进行GIS空间叠置，结合数理统计分析，对江浦2000～2006年这段时间内土地利用类型的变化进行了时空变化分析，揭示了该区土地利用类型变化的数量特征和空间变化特征，全面分析了影响土地利用类型变动的经济、人口、政策等主要因素，并对本地区未来几年的土地利用变化趋势做了预测。

Reviewing the patterns of the landuse in the suburb area is greatly important to efficient and reasonable urban planning. Based on remote sensing images of 1988, 2000 and 2006,through classifying and analyzing, we achieve the process of land use change from 1988 to 2006 in Pukou area in Nanjing,then overlay and analyze the images of 2000 and 2006. Using data obtained from interpretation of remote sensing images and other statistical sources, land use changing patterns and their driving forces including economy, population and policies were analyzed. Finally, the trend of the land use change in this area is forecasted.
