| 城市的发展伴随而来的生物栖息地丧失、生境斑块破碎、孤岛化等生态问题日益严重。构建生态网络能有效促进斑块源地之间的生态流动，提高生态服务价值，改善生态环境问题。以漳州市为研究对象，基于电路理论，运用MSPA分析方法和景观连通性指数选取生态源地，利用Linkage Mapper工具识别生态廊道、生态夹点和障碍点，基于重力模型判别廊道等级，结合生态关键点构建生态网络。结果表明，研究区共识别出79条生态廊道，其中25条为重要廊道,景观构成要素以林地和草地为主，主要分布在西部,越靠近东部地区，斑块破碎化程度越高。针对生态源地分布不均，廊道过长，障碍点阻碍生态功能等问题，提出在今后的建设中可通过新增生态源地，保护夹点，设置踏脚石和修复障碍点对生态网络进行优化，以提高生态网络的连通性，促进区域内的生态流动和物种迁徙。 |

| With the development of cities, ecological problems such as habitat loss, habitat fragmentation and isolated are becoming more and more serious. The construction of ecological network can effectively promote the ecological flow between patches, improve the value of ecological services and improve the ecological environment. Taking Zhangzhou City as the research object, based on the circuit theory, the ecological source was selected by using MSPA analysis method and landscape connectivity index, the ecological corridor, ecological pinch points and obstacle points were identified by using the Linkage Mapper tool, the corridor grade was determined by the gravity model, and the ecological network was constructed by combining the ecological key points. The results showed that 79 ecological corridors were identified in the study area, of which 25 were important corridors, and the landscape elements were mainly forest land and grassland, distributed in the eastern part of the study area, and the closer to the east, the higher the degree of patch fragmentation. Aiming at the problems of uneven distribution of ecological sources, long corridors and obstacles hindering ecological functions, this paper suggested to optimize the ecological network by adding new ecological sources, protecting pinch points, setting stepping stones and repairing obstacles, so as to improve the connectivity of the ecological network and promote the ecological flow and species migration in the region. |
