| 中文摘要: |
| 运用MaxEnt模型评估南京市震旦鸦雀潜在生境适宜性与环境变量的贡献度，分析主导环境变量对震旦鸦雀分布的影响并探究其空间分布规律。结果表明：影响震旦鸦雀生境适宜性的关键环境变量是年温度变化范围（407%）、最干季度均温（198%）和人口密度（121%），震旦鸦雀偏好选择温度波动大、平缓近水、人为干扰小的芦苇荡湿地生境；震旦鸦雀在南京市的适宜生境总面积为40684km2，占南京市总土地面积的618%。建议优先保护长江沿岸、石臼湖及固城湖等周边的芦苇湿地，控制人为干扰强度，维持自然水文节律，以保障震旦鸦雀的长期栖息需求。 |

| The MaxEnt model was utilized to assess the suitability of potential habitats for Paradoxornis heudei（P. heudei）in Nanjing. This study determined the contributions of environmental variables， analyzed the impacts of dominant environmental factors on its distribution， and investigated its spatial distribution patterns. The results indicated that key environmental determinants for P. heudei were annual temperature range （407%）, mean temperature of the driest quarter （198%）, and population density （121%）. The species preferred reed wetland habitats with large temperature fluctuations, low gradient riparian transition zones, and low human disturbance. A total of 40684 km2 of suitable habitat was identified within Nanjing, accounting for 618% of the municipal territory. It was recommended to prioritize the protection of reed wetlands along the Yangtze River， as well as around Shijiu Lake and Gucheng Lake， control human interference and maintain natural hydrological rhythms to ensure long term habitat requirements for P. heudei. |
