| 生态保护空间格局及其连通性对保护生物物种和维持局域生物多样性具有重要作用。本研究以长江口海域空间利用管理模式为基础，利用形态学空间格局分析(Morphological Spatial Pattern Analysis, MSPA)和景观连通性模型，研究长江口海域生境特征，识别重要生态源地及其连通性，并分析其与现有保护格局的匹配性，以期为长江口海域生态系统整体保护、系统修复、综合治理提供支持。研究结果表明：长江口海域15块保护空间中，识别重要生态源地12个，总面积约为3080 km2，占上海市海洋功能区划面积的28.6%。重要源地主要分布于长江口南支及附近海域。连接12个生态源地的生态廊道23条。本研究识别的长江口门内生态源地空间与上海市最新公布的海洋生态保护红线空间匹配性较好，但连接南支和北支口门附近的重要保护空间不足。 |

| Abstract: |
| The ecological space protection pattern and its connectivity play an important role in maintaining local biodiversity. This study is based on the spatial utilization management of theYangtze River Estuary (YRE) in Shanghai，and uses morphological spatial pattern analysis (MPSA) and landscape connectivity models to study the habitat characteristics of the YRE based on the spatial management model of the sea area. It identifies important ecological source areas and their connectivity and analyzes their compatibility with the existing protection pattern in order to contribute to the integrated protection of the YRE. Results indicate that there are 12 main ecological source areas in the YRE，with a total area of approximately 3080 km2 accounting for 28.6% of the areas of Shanghai’s Marine Functional Zoning. The important source areas are mainly located in the southern branch of the YRE and the nearby sea area with 23 ecological corridors connecting 12 ecological source areas. The ecological source space identified in this study matches well with the latest marine ecological protection red line space announced. However，the important protection space is insufficient outside the river mouth，especially in important protection space near the southern and northern branches. |
