【摘要】 以南通市区为研究区域,利用Landsat系列卫星遥感影像作为数据源,基于ENVI5.3图像分析和ArcGIS 10.2软件解译和提取土地利用变化信息,获取南通市区2003—2018年间6期土地利用/覆盖分类图,并通过珞珈一号夜光遥感影像检验分类的可靠性。在此基础上,利用数理统计和动态度分析的方法,查明各地类面积变化的情况,探求其土地利用类型间的相互转移关系,从而分析南通市区土地利用变化的驱动力。结果表明:2003—2018年,南通市区土地利用类型中,耕地所占面积比重最高且呈下降趋势,而建设用地呈明显的增加态势,其他用地的面积变化较小;交通、人口和产业结构等因素是南通市区土地利用变化的主要驱动力。更多还原

【Abstract】 Taking Nantong as the research area, the Landsat series of terrestrial resources satellite imagery is used as the data source, based on ENVI5.3 image analysis and interpretation of ArcGIS 10.2 software and extraction of land use change information, Nantong land use/coverage classification map from 2003 to 2018 is acquired, and the reliability of classification is tested by the Luojia1-01 night light remote sensing image. On this basis, the methods of mathematical statistics and dynamic analysis are used to find out the changes of regional area and explore the mutual transfer relationship between land use types, so as to analyze the driving force of land use change. The results show that from 2003 to 2018 the cultivated land has the highest proportion of the arable land and shows a downward trend,while the construction land enjoys a significant increase, and there is relatively small change in other land areas. The main driving factors behind this are identified as transportation, population and industrial structure.更多还原
