Abstract:Under the guidance of the goal of modernizing the harmonious coexistence between humans and nature, optimizing nature-based recreational spaces has become an important task in the development of human settlements. Taking Guangming District, Shenzhen as an example, and based on the theory of landscape ecological security patterns, this study employs methods such as morphological spatial pattern analysis (MSPA), graph theory-based connectivity assessment, the minimum cumulative resistance (MCR) model, and circuit theory to establish an analytical framework consisting of 'habitat matrix identification—high-quality patch selection—corridor network identification and diagnosis—overall pattern integration'. The results show that the animal habitat-oriented landscape ecological security pattern in Guangming District comprises three elements: a key habitat network consisting of high-core areas (including 10 country parks and 12 urban parks), 172 habitat corridors at three levels, and 17 pinch points; 6 road barrier points (such as Gongchang Road and Longda Highway); and 7 types of habitat matrices (core areas, edge areas, etc.). This pattern faces three risks: insufficient synergy among 'humans, animals, and the environment,' fragmentation of ecological flows by barrier points, and underutilized functional potential of matrix elements. Based on the analysis results and practical experience, a three-level optimization strategy is proposed: enhancing network connectivity, restoring barrier points, and improving basic habitats.
