Urban planning often faces issues of spatial separation between blue and green spaces, as well as the lack of integration in slow traffic networks. The development and shaping of urban slow, blue, and green spaces often proceed along separate paths. However, building an ecological and livable city requires the integrated development of slow, blue, and green spaces. Taking the central urban area of Wuhan as a case study, this research uses ArcGIS visualization, walking accessibility analysis, and landscape pattern index analysis methods. By overlapping slow traffic spaces with blue and green spaces, the study explores the distribution of slow, blue, and green spaces and the integration characteristics of slow + blue-green spaces, categorizing them based on walking time and spatial aggregation. The results show: 1) In the central urban area of Wuhan, blue spaces are predominant in the Yangtze River basin, the Han River-Sha Lake-East Lake-South Lake, Yangchun Lake-East Lake-South Lake-Yezhi Lake, and Longyang Lake-Moshui Lake directions, with clear dominant patches, while other areas show average performance; 2) Green spaces have good patch dominance and connectivity along the Qingshan Park-East Lake Greenway-Moshan-Ma'anshan Forest Park; 3) The integration of blue and green spaces is best along the Yangtze River, East Lake, and South Lake; 4) Areas such as Sha Lake Park in Wuchang District, East Lake Scenic Area in Hongshan District, the South Lake-Yezhi Lake corridor, Moshui Lake and Longyang Lake in Hanyang District, and the northern and southern parts of the Yangtze River are characterized by better integration of slow blue-green spaces. Through the overlay analysis of walking accessibility and landscape pattern indices of blue-green spaces, the study significantly reflects the integration characteristics of slow blue-green spaces in Wuhan's central urban area. This research aims to provide references for the planning and design of urban slow blue-green spaces and the construction of livable and ecological cities, offering practical guidance for creating a healthy urban ecological living environment and for urban ecosystem restoration and management. |
