摘要：

土地利用变化驱动机制研究是地理学研究的热点，而研究土地利用变化与影响因子关系是揭示土地利用变化驱动机制的关键。胶东地区是社会经济发展迅速的地区，选取该地区作为土地利用变化与影响因子关系研究区域具有重要的理论和现实意义。把胶东地区20世纪80年代和2000年的土地利用矢量数据相叠加，提取出主要土地利用类型发生变化的区域，统计出各变化类型的面积及其占总变化面积的比例，并构建出土地利用变化样本数据矩阵。把土地利用变化数据与胶东地区的城镇位置、道路、DEM、人口密度、GDP和海岸线位置等数据进行叠加分析，提取出土地利用变化图斑的影响因子，构建出土地利用变化的影响因子矩阵。在此基础上，应用典范对应分析方法(CCA)研究胶东地区土地利用变化与其影响因子的关系。结果显示，城镇化、建设用地扩展和耕地大量减少是该时期胶东地区土地利用变化的主要特点。人口密度、到城镇距离、高程和到主要公路距离是决定胶东地区主要土地利用变化类型分布的主要影响因子，其次为GDP和到海岸线距离。耕地转化为城镇用地和农村居民点转化为城镇用地多分布在人口密度大、GDP高、到城镇距离近和到主要公路距离近的区域；耕地转化为农村居民点多分布在海拔低、到城镇距离较近和到主要公路距离较近的区域。

Abstract:

The research on driving mechanism of land use change has been a hot spot in geography， and the research on relationship between land use change and influencing factors is a key for revealing driving mechanism of land use change. Jiaodong region in China witnessed rapid socical and economic development from the 1980s to 2000. Study on relationship between land use change and influencing factors in this region has important theoretic and practical significance. Vector data of land use of Jiaodong region in the 1980s and 2000 were overlaid each other， and the regions of land use change were obtained. The area of major land use conversion types and their proportion to total change area were calculated and the matrix of land use change samples was constructed. The data of land use change and the data of urban site， road， DEM， population density， GDP and coastal line were overlaid respectively， influencing factors of land use change spots were obtained， and the matrix of influencing factors of land use change was constructed. Based on these data， Canonical Correspondence Analysis (CCA) was used for revealing the relationship between land use change and influencing factors. The study result showed that urbanization， expansion of construction land and substantial decrease of farmland were the main characteristics of land use change in Jiaodong region from the 1980s to 2000. Population density， the distance between land use change site and urban site， elevation， and the distance between land use change site and main road were the main influencing factors for distribution of major land use conversion types， and the next were GDP and the distance between land use change site and costal line. The conversions of farmland to urban land and rural residential land to urban land were mainly in the areas near urban sites and main roads with high population density and high GDP. The conversions of farmland to rural residential land were mainly in the areas near urban sites and main roads with lower elevation.
