uzhou Metropolitan Area is one of the three major metropolitan areas in Jiangsu Province. In recent years, the urbanization process has accelerated, and the impact on the landscape pattern of blue-green space has gradually strengthened. Using the natural land cover data of 2000, 2010 and 2020 as the data source, based on the landscape dynamics, landscape transfer matrix method, and landscape index method, ArcGIS 10.8 and Fragstats 4.2 software were used to dynamic analyze the blue-green spatial scale and landscape pattern of the Xuzhou metropolitan area. The results show that: (1) From 2000 to 2020, the scale of blue-green space is decreasing, the surface area of artificial land is increasing, and the rate of change accelerates. Among them, the area of blue space has shrunk significantly, mainly flowing to cultivated land and artificial land, while the area of green space has slowly increased, mainly from cultivated land. (2) During the research period, the green space is characterized by the first fragmented heterogeneity and then agglomeration homogeneous. On the other hand, the blue space and the blue-green space are characterized by the first agglomeration homogeneity and then fragmented heterogeneous, and the overall spatial pattern tends to be complicated. (3) The evolution of the blue-green spatial landscape pattern is affected by human activities such as policies, development, and construction. Furthermore, urbanization development has gradually become the main influencing factor.
