摘 要:选择位于杭嘉湖平原地区社会经济快速发展的浙江省海盐县为研究区,利用遥感数据,对研究区土地利用类型的空间转移与格局变化进行分析的基础上,选取研究区土地利用变化的社会经济驱动因子,运用典型相关分析方法诊断各社会经济驱动因子对土地利用变化格局形成贡献作用的大小,同时运用典型相关系数和冗余度分析,检验了分析结果。研究结果表明,人口密度、单位面积工业总产值、单位面积农业总产值、城镇化水平、农民人均年纯收入等5个因子是影响研究区土地利用变化的主要社会经济驱动因子。[著者文摘]

RESEARCH ON DRIVING FACTORS AFFECTING LAND USE CHANGE IN THE HANG- JIA- HU PLAINTAN Yong- zhong , WU Ci - fang , WANG Qing- ri(1. College of Public Administration, Zhejiang University, Hangzhou 310029, Zhejiang, China; 2. Institute of Land Surveying and Planning in China, Beijing 100037, China)Abstract:Taken Haiyan county in Zhejiang province being located in the Hang- Jia= Hu Plain as an instance, used the interpretation of remote sensing image data in 1986, 1995 and 2000, based on the analysis of the spatial shifting and pattern change of land use types. Driving factors are selected according to the characteristics of land use change and social and economic development in the study area. Canonical Correlation Analysis (CCA) is applied to analyze the land use change and external driving factors, by which the contributions of each factor to the forming of land use pattern are drawn. At the same time, the coefficient of CCA and redundancy degree is used to verify the analysis results. The results show that in the internal driving factors the effects of the nearest distance to the towns and other residential areas and the distance to the main roads are remarkable. The population density, gross annual value of industrial output per unit area, gross annual value of agricultural output per unit area, urbanization standard and per capita annual net income of peasant are important external driving factors.[著者文摘]

Key words:land use change; driving mechanism; CCA; Haiyan county
