| Abstract: |
| To enhance the connectivity and ecological functions of urban blue -green spaces, this study
took Huizhou City in Guangdong Province as a case study. Based on Landsat remote sensing image data from
2000, 2010, and 2020, blue-green spaces were identified through Morphological spatial pattern analysis (MSPA). By integrating data from nature reserves and ecological protection areas, key ecological source areas were delineated. Four categories of resistance factors, including land use, topography, human disturbance, and ecological protection, were comprehensively analyzed. The Analytic hierarchy process (AHP) was employed to
determine the weights of each factor and generate a comprehensive resistance surface. Combined with the Minimum cumulative resistance (MCR) model, ecological corridors were extracted to construct an ecological network. The results show that: (1) 71 ecological sources were identified, covering an area of 1 140. 95 km

,
mainly distributed in the northwest, southeast, and southern parts of the city with high fragmentation. (2) The
comprehensive resistance surface exhibits a spatial pattern of "high resistance in the southwest and low resistance
in the northeast". (3) 21 ecological corridors were identified, totaling 1 223. 72 km in length, some of which
traverse areas with intensive human activity. Based on the research results, strategies are proposed to strengthen
the protection of key ecological sources, optimize corridor management in high-interference areas, and promote
the coordinated improvement of water and green spaces, in order to support the optimized allocation and spatial
layout of blue-green spaces in Huizhou City. |
