| 摘 要： | 以延庆县为研究对象,通过采用转移矩阵、重心模型及景观格局指数来探讨其土地利用及景观格局的变化情况。在此基础上,以主要土地类型间的转化为因变量,以高程、坡度、距建制镇的距离等内在驱动因子为自变量,借助SPSS技术分析它们之间的相关性。此外,还探讨了政策因素、经济发展因素、人口因素对土地利用变化的影响。

| Abstract: | With Yanqing County as the study object,the land use and landscape pattern change were discussed by using the land use transfer matrix,gravity center model and landscape indexes.On this basis,taking the changes among the main land types as the dependent variable,and elevation,slope,distant from towns as the internal variables,the correlation between them were analyzed by using SPSS technology.In addition,the influences of policy factors,economic factors,demographic factors on land use change were discussed. |
