摘　　要：徐州都市圈是江苏省三大都市圈之一。近年城镇化进程加快,对蓝绿空间景观格局的影响逐渐增强。以2000、2010、2020年自然土地覆被数据为数据源,基于景观动态度、景观转移矩阵法和景观指数法,运用ArcGIS10.8和Fragstats4.2软件,对徐州都市圈的蓝绿空间规模和景观格局进行动态分析。结果表明:(1)2000-2020年,蓝绿空间规模不断减少,人造地表面积不断增加,且变化速率加快。其中蓝色空间面积缩减显著,主要流向耕地、人造地表,绿色空间面积缓慢增加,主要源自耕地。(2)研究时段内,绿色空间表现为先破碎异质后集聚同质的变化特征,蓝色空间与蓝绿空间表现为先集聚同质后破碎异质的变化特征,空间格局总体趋向复杂化。(3)蓝绿空间景观格局演变受政策、开发建设等人为活动影响,且城镇化发展是主要影响因素。Xuzhou 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.
