Abstract

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., built-up 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.

期刊介绍： The COSPAR publication Advances in Space Research (ASR) is an open journal covering all areas of space research including: space studies of the Earth''s surface, meteorology, climate, the Earth-Moon system, planets and small bodies of the solar system, upper atmospheres, ionospheres and magnetospheres of the Earth and planets including reference atmospheres, space plasmas in the solar system, astrophysics from space, materials sciences in space, fundamental physics in space, space debris, space weather, Earth observations of space phenomena, etc. NB: Please note that manuscripts related to life sciences as related to space are no more accepted for submission to Advances in Space Research. Such manuscripts should now be submitted to the new COSPAR Journal Life Sciences in Space Research (LSSR). All submissions are reviewed by two scientists in the field. COSPAR is an interdisciplinary scientific organization concerned with the progress of space research on an international scale. Operating under the rules of ICSU, COSPAR ignores political considerations and considers all questions solely from the scientific viewpoint.
