摘要 以湖南醴陵市为研究案例,利用遥感影像、土地利用分类数据、野外调查资料和社会经济统计资料等多种数据,借助遥感与地理信息系统技术、因子分析和回归分析等方法定量地开展了中南丘陵区土地利用变化及人文驱动因素研究。结果表明,近15年来,醴陵市土地利用发生了明显的变化,主要表现为水田、旱地、园地和未利用地持续减少,城乡建设用地和林地快速增加;应用因子分析将醴陵市土地利用变化的人文因素可以归纳为经济发展、人口增长、产业结构调整和技术进步4个因子;应用多元线性回归分析将人文因子对土地利用变化的影响作用表达为函数关系,从中可知各人文因子对土地利用变化的影响作用不同,其中经济发展和人口增长因子的作用最大,产业结构调整和技术进步因子次之。 In this paper,taking the Liling as the case,a thorough and careful study on the land use changes and human dimensions was conducted in hilly area of Central-South China using GIS spatial analysis and statistical analysis with remote sensing images,land use map,materials from field measurements and statistical data.The results showed that in plain area,the main character of land use changes were the decreasing of paddy field and the increasing of construction land.In lower hilly area,the major land use change was the decreasing of orchard and unused land.In higher and steeper hilly area,the dominant land use types were dry land which was decreaseing and woodland which was increaseing.Using factor analysis,four main factors that impacted land use changes in Liling were identified as economic development,population growth,industrial structure and technology development.Using linear regression,the impacts of different factors on land use change in Liling were revealed,the factors of population,economic development had more impacts on urban land use than that of industrial structure and technology development.
