Quantitative Study of the Spatiotemporal Evolution and Driving Mechanism of Landscape Pattern in Energy Intensive Cities:A Case Study of Datong City,Shanxi Province
The evolution of landscape pattern reflects the laws of land use change,and the analysis of the evolution and driv-ing 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 geo-graphic 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.
