| 构建生态安全格局是落实生态文明战略的重要途径。本研究以辽宁省葫芦岛市为研究对象，基于FLUS模型预测葫芦岛市2030年不同情景下的土地利用结构与布局，并结合土地利用预测数据，耦合使用形态学空间格局分析（MSPA）和MCR模型，构建葫芦岛市生态安全网络，提出相应的生态建设思路。FLUS模型模拟结果显示，2030年葫芦岛市不同情景下的土地利用布局总体相似、“三生空间”结构变化有所差异。生态保护情景下的生态安全网络结构更复杂、连通性更高，共识别出该情景下的生态源地25个，主要分布在建昌县、绥中县；生态廊道50条，总长度986.89 km，整体呈中西部密集、东部沿海地区稀缺的蜘蛛网状，呈西南-东北方向带状延伸态势；生态节点36个，断裂点97个，主要位于白狼山与虹螺山生态廊道、灵山与虹螺山生态廊道等处。基于生态安全网络，提出“一核三区四带多点”的生态安全格局构建策略，以实现葫芦岛市生态系统服务功能持续提升，为葫芦岛市生态保护优化提供科学建议。 |

| Building an ecological security pattern is an important way to implement the strategy of ecological civilization. Taking Huludao City, Liaoning Province as the research object, the FLUS model was used to predict the land use structure and layout of Huludao City under different scenarios in 2030. Combined with land use prediction data, MSPA and MCR models were coupled to construct the ecological security network of Huludao City, and corresponding ecological construction ideas were proposed. FLUS model simulation results showed that the overall land use layout in different scenarios of Huludao City in 2030 was similar, and there were differences in the changes in the “three living spaces”structure. The four differentiated scenarios set were basically suitable for the different development directions of Huludao City in the future. Under the ecological protection scenario, the ecological security network structure was more complex and had higher connectivity. A total of 25 biological source areas had been identified, mainly distributed in Jianchang County and Suizhong County. There were 50 ecological corridors with a total length of 986.89 km, forming a dense spider web pattern in the central and western regions, and a rare spider web pattern in the eastern coastal areas, extending in a southwest-northeast direction. There were 36 ecological nodes and 97 fault points, mainly located in the ecological corridors of Bailang Mountain and Hongluo Mountain, as well as the ecological corridors of Lingshan and Hongluo Mountain. The study proposed an ecological security pattern construction strategy of“one core, three zones, four belts, and multiple points”to achieve continuous improvement of the ecosystem service function in Huludao City. The research results can provide scientific suggestions for optimizing ecological protection in Huludao City. |
