摘　　要：基于蓬莱市2008年、2013年和2018年的Landsat TM/OLI遥感影像数据,在RS和GIS技术的支持下分析该地区的土地利用类型变化,以及2008-2018年间土地利用的时空特征.结果表明:2008-2013年间,土地利用变化最显著的为建设用地扩张,草地、水体面积显著减少,耕地、林地面积有一定程度增加,该时间段研究区所有土地利用/覆被类型的双向转换较为频繁,草地转化为耕地的幅度较大.2013-2018年间,土地利用变化为水体面积增加明显,耕地、建设用地面积有一定程度增加,林地、草地面积有一定程度减少.2008-2013年间研究区所有土地利用/覆被类型的双向转换程度相对较低.The quantitative evaluation on land use change at a large scale is significant to the sustainable use of local land resource.Based on three sets of Landsat data(2008,2013 and 2018)of Penglai City,the land use status and land use change information in the year of 2008,2013 and 2018 were extracted by integrating TM images with Remote sense software.With the technology of GIS,the paper revealed the temporal and spatial characteristics of the land use in the past 10 years.The results showed that big changes have taken place in land use patterns in Penglai City from 2008 to 2018.The expansion of construction land was most evident,and the area of grassland and water decreased slightly,while the farmland area and forest increased more rapidly from 2008 to 2013.In the view of the transition matrix of the land use conversion from 2008-2013,there was frequent bidirectional conversion of all land use patterns in Penglai City,and the extent of conversion from grassland to farmland was larger.The area of water increased slightly,and the farmland area and construction land area was correspondingly increased,while the grassland area and forest area was accordingly decreased from 2013 to 2018.The bidirectional conversion of all land use patterns was relatively low from 2013 to 2018.Analysis of the reasons for the transformation shows that the implementation of industrial adjustment policies and development incentives by the government directly promotes the mutual transformation of various land types.Industrial agglomeration drives employment,thus attracting population agglomeration.Moreover,the development of various advantageous industries driven by comparative economic interests also indirectly promotes the transformation of various land types.This paper makes up the gap in the study of land cover change on a long-term scale in Penglai City,and lays a foundation for the sustainable utilization of land resources and ecological environmental protection in this area.
