| 摘 要： | 生态安全格局构建是保障生态系统稳定运行，实现区域生态安全的重要途径。本文以重庆市为例，基于生态服务功能和生态敏感性对重庆市进行生态重要性评价，将生态极重要区域与自然保护地共同作为生态源地。首先从生态本底和生态胁迫两个角度选取高程、坡度、土地利用类型、距道路距离、距水体距离、夜间灯光指数6个阻力因子构建了典型山地动物的生态阻力面，然后利用最小累积阻力模型（MCR）模拟潜在生态廊道，完成市域生态安全格局的构建。研究表明，重庆市生态源地30 751.11 km2，占全市总面积的37.32%，主要分布在渝东北与渝东南的山林地。将识别的73条潜在生态廊道、138个生态节点与生态源地进行叠加，结合重庆的山水格局，构建了"两区、三带、四核、多廊、多点"的多层次生态安全格局，为重庆市生态保护和修复工作提供科学参考。

| Abstract: | The construction of ecological security pattern is an important way to ensure the stable operation of ecosystem and realize regional ecological security. This article takes Chongqing as an example, evaluates the ecological importance of Chongqing based on its ecological service functions and ecological sensitivity, and takes high-level areas of ecological importance and nature reserves as the ecological source. Six resistance factors, including elevation, slope, land use type,distance from road,distance from waterbodyand night light index, are selected from the ecological background and ecological stress to construct the ecological resistance surface of typical mountain animals, and the minimum cumulative resistance model (MCR) is used to simulate the potential ecological corridors, and then the urban ecological security pattern is constructed. The research shows that the ecological source area of Chongqing is 30 751.11 km2, accounting for 37.32% of the total area of Chongqing, which is mainly distributed in the mountain forest land in the northeast and southeast of Chongqing. The identified 73 potential ecological corridors and 138 ecological nodes are superposed with ecological sources, and combining with the landscape pattern of Chongqing, a multi-level ecological security pattern of "two regions, three belts, four cores, multiple corridors and multiple points" was constructed, which provided scientific reference for ecological protection and restoration work in Chongqing. |
