摘　　要：景观格局演变反映了土地利用变化的规律,能源型城市景观格局演变与驱动机制的分析对城市的转型与发展具有参考意义。通过土地利用动态度及土地利用转移矩阵,分析大同市2010年至2020年土地利用变化情况,并利用Fragstats软件计算景观格局指数以及使用地理探测器对驱动机制进行分析,探究其演变特征。结果表明:草地是大同市优势土地类型,占比约80%,2010年至2020年期间草地面积不断减小,耕地、林地、水域、建设用地面积不断增加;大同市景观格局破碎化程度上升,连接性变差;第一产业增加值、第三产业增加值、年降雨量、年平均温度是大同市景观格局演变的主要驱动力。The evolution of landscape pattern reflects the laws of land use change,and the analysis of the evolution and driving mechanism of landscape pattern in energy intensive cities has reference significance for the transformation and development of cities.Taking Datong City,a typical energy city,as an example to analyze the land use changes in Datong City from 2010 to 2020 using land use dynamics and land use transfer matrix.Fragstats software is used to calculate the landscape pattern index and geographic detectors are used to analyze the driving mechanism,exploring its evolution characteristics.The results are as follows:(1)Grassland is the dominant land type in Datong City,accounting for about 80%.During the period from 2010 to 2020,the grassland area continued to decrease,while the cultivated land,forest land,water area,and construction land area continued to increase.(2)The degree of fragmentation in the landscape pattern of Datong City is increasing,and the connectivity is deteriorating.(3)The main driving forces for the evolution of the landscape pattern in Datong City are the added value of the primary industry,the added value of the tertiary industry,annual rainfall,and annual average temperature.
