摘要：
Information on green space coverage patterns and influencing factors in built-up areas is essential for urban planners, as it is related to the well-being of residents. In this study, WorldCover land cover product was used to extract green space maps and analyze landscape patterns of urban green space coverage (UGSC) of built-up areas in China's Yangtze River Delta region under different scales (i.e., builtup area, district/county, and prefecture-level city) in 2020. Additionally, cold and hot spot analyses were performed to represent the regional aggregation of high and low green space coverage. The random forest model was used to calculate the relative importance and marginal effect of the factors influencing UGSC. The results show that, in general, the UGSC gradually decreases from the southern to the northern regions. The pattern of UGSC is basically the same as that of tree/shrub coverage. Precipitation, the size of built-up area, and the area of urban paved roads are the main influencing factors of UGSC. Nonlinear relationships are observed between the size of built-up areas and UGSC, as well as between the area of urban paved roads and UGSC. The detailed mapping of the UGSC pattern and identifying key influencing factors offer valuable insights for urban planning and sustainable development. (c) 2024 COSPAR. Published by Elsevier B.V.
