Abstract: Building urban green ecological network systems and increasing urban and rural landscape connectivity are effective ways to improve urban biodiversity and landscape sustainability. The ecological sources in the main urban area of Qingdao City (Shandong, China) were identified based on morphological spatial pattern analysis (MSPA) combined with a biodiversity conservation function assessment, with the ecological corridors established and the ecological network structure optimized. The results showed that (1) the study area lacked high-quality patches with strong landscape connectivity; (2) the potential green ecological network of the study area was composed of 38 ecological sources, 703 ecological corridors, and 284 ecological nodes, effectively connecting urban and suburban green spaces; (3) after optimization, the green ecological network contained a total of 223 important corridors and 61 key nodes, with significantly increased network connectivity; (4) the optimal ecological corridor width in Qingdao was determined to be 30 m. Our study provided important guidance for the construction of ecological security patterns and scientific evidence to support urban green space planning and sustainable development in Qingdao.
