Abstract: 【Objective】 To clarify the land change and landscape pattern in the upstream area of Hutuo River basin from 2000 to 2018,and provide a reasonable basis for the ecological environment protection and sustainable development in the area.【Methods】 Fragstats 4.2 software was used to analyze the landscape pattern of land use data in the upstream area of Hutuo River basin in 2000,2005,2010,2015 and 2018,and study the landscape pattern spatial-temporal change in the area,and to analyze the driving mechanism of the landscape pattern change with the gray correlation analysis.【Results】 From 2000 to 2018,the area of grassland in the upstream area of Hutuo River basin was absolutely dominant. In the transfer of land use area,the transfer area of cultivated land to grassland was relatively large,which was mainly used for construction land. From 2000 to 2018,the landscape in the upstream area of Hutuo River basin showed a trend of diversified and fragmented characteristics. The gray correlation analysis showed that the proportion of the secondary industry,the proportion of the tertiary industry,the per capita grain output and the average annual temperature were the main driving forces for the changes in the landscape pattern in the upstream area of Hutuo River basin.【Conclusion】 From 2000 to 2018,the land use structure in the upstream area of Hutuo River basin had changed,the construction land had increased significantly,the fluctuation of grassland,cultivated land,and forest land had decreased,and the water area and unused land had changed little. The development of urbanization,the development of agriculture and various ecological constructions were the main reasons promoted the change of the landscape pattern in the upstream area of Hutuo River basin.
