With the rapid development of urbanization, the distribution of urban green space is increasingly affected by urbanization. Based on the land use data of 2000, 2010, and 2020, This study revealed the spatial-temporal change characteristics of green space in the process of urban expansion in Qinhuangdao City, applying the spatial analysis method in ArcGIS10.5 software and landscape expansion index analysis method. The results showed that from 2000 to 2020, the green space shrank and the non-green space expanded in Qinhuangdao city. The cultivated land decreased by 210km², while the grassland, forest land, and water bodies decreased slightly and remained relatively stable. From the perspective of the transfer matrix, the transformation between 2000 and 2020 is mainly among cultivated land, urban construction land, and other construction land. Among them, the transformation area of cultivated land during 2000-2010 is significantly higher than that during 2010-2020, and its transformation trend is consistent with the development direction of urbanization. Edge-expansion is the dominant type, in which the cultivated land converted into urban construction land is the largest, concentrated in the surrounding areas, especially the western and northern areas of the Haigang District and the eastern and southern areas of the Shanhaiguan District. The results of the study identified the urban expansion mode of Qinhuangdao, which was dominated by edge-expansion, and the most obvious change characteristics of cultivated land affected by the green space type, thus providing a scientific reference for the green space planning and ecological construction of Qinhuangdao city.
