摘　　要：以2001年和2013年2期Landsat影像为数据源,采用ENVI的监督分类和分类后处理功能,并结合土地利用动态度分析模型和转移矩阵分析法,对日照市的主要土地利用类型数量变化特征、土地利用动态度和土地利用类型之间的转移特征进行了研究。结果表明,在2001—2013年,日照市的土地利用类型发生了显著变化,主要表现在耕地、林地、建筑用地和未利用地等方面。其中,耕地面积减少446.08km2,年变化率为-2.22%,主要转化为建筑用地和未利用地;林地面积减少192.55km2,年变化率为-2.43%,主要用于建筑用地和耕地,也有部分被转化成未利用地;建筑用地呈现持续增加的态势,2001—2013年,建筑用地面积增加一倍多,年变化率为8.05%,主要来自于未利用地和耕地;未利用地面积减少265.69km2,年变化率为-1.16%,主要被用于建筑用地。最后分析了引起土地利用变化的主要驱动因子,认为主要驱动因子是城市化进程、社会经济的发展、人口增长和人类活动。研究成果可为区域土地持续利用提供决策依据。Taking the 2001 and 2013 Landsat images as data sources, we discussed the land use dynamic change in Rizhao City, Shandong Province. By using the supervised classification and post processing func- tion of the ENVI software, and combining the dynamic analysis with the transference matrix models of land- use, we analyzed the major patterns of land use in Rizhao City, and revealed the spatiotemporal change char- acteristics, dynamic degree of land use change and the transference characteristics of land use types. The re- sults showed that significant changes had taken place in terms of land use mode from 2001 to 2013 in Rizhao City. Among them, farmland had reduced 446.08 km2 , with an annual rate of 2.22~, which was mainly converted to construction land and virgin land. Forestland had reduced 192.55 km2 , with an annual rate of 2.43%, which was mainly used as construction land, farmland and virgin land. Construction land changed significantly from 2001 to 2013. The increased area was more than twice, and the annual rate had reached to 8.05%, which mainly came from virgin land and farmland. Virgin land had reduced 265.69 km2 , with an an- nual change rate of --1.16%, which was mainly used as construction land. Finally, the main driving factors of land use change were analyzed. The results showed that the main driving factors were urbanization process, the social and economic development, the population growth and the human activities. These re- search results will be of most importance for decision-making of land utilization of this region.
