Abstract: In the context of ecological protection and regional development, reasonable planning of the spatial hierarchy of landscape architecture can significantly enhance the stability of the ecosystem. To optimize the spatial hierarchy of landscape architecture, this paper selected the A-landscape architecture in southern China as the research object. Subsequently, the multi-model coupling calculation method is employed to construct the ecological network, and a hierarchical optimization strategy based on ecological network evaluation is designed. In the multi-model coupling calculation method, this study uses Morphological Spatial Pattern Analysis (MSPA), Spatial Principal Component Analysis (SPCA), and Minimum Cumulative Resistance (MCR) models to comprehensively analyze ecological source areas, ecological resistance, and ecological corridors. The results demonstrate that 30 potential ecological source areas are identified and divided into 10 primary, 7 secondary, and 5 supplementary (tertiary) ecological corridors. The threshold for selecting ecological source areas is that the patch area is greater than 2 km2 and the buffer zone width in key corridors is at least 100 m. After optimization, the ecological network integrity index of different regions of the research object increases, such as from 0.68 to 0.89 in the southern region and from 0.54 to 0.72 in the northern region, and the landscape function index is above 0.80. The optimized biodiversity index shows a maximum increase of 0.32, while the ecosystem service value index remains above 0.75. Through the proposed measures of ecological island restoration, key corridor strengthening, and core area radiation enhancement, this study has achieved hierarchical optimization of landscape space and significantly improved the connectivity of ecological networks and ecosystem service functions. This study can provide quantitative methods and practical references for optimizing landscape space.
