摘　　要：以唐山市为例,重点面向气候变化情况下的生物栖息地预测,结合现有保护地、预测生态源地,整合多种生态系统服务重要性,依托最小累积阻力模型计算生态空间网络,并将区域生态肌理与生态空间网络进行整合,实现对唐山市生态安全格局的构建,最后基于生态安全格局提出生态空间管控要求。结果表明,构成以生态肌理为基础的,整合生态源地和生态廊道的生态安全格局,形成区域生态网络体系,有效提升生态系统之间的连通性,促进生态物质和能量的流动。整合多种生态服务功能评价,并应用于阻力面构建和生态廊道提取,结合唐山市生态保护修复需要重点、现状河湖水体及河岸带的水生态安全、未来发展需求,构建两级生态廊道体系,以提升生态廊道的连通性。该研究解决了生态源地功能指向现状而非面向规划的问题,为其他底图国土空间规划提供决策支撑。Taking Tangshan City as an example,this study focused on biological habitat prediction under climate change,combined existing protected areas and predicted ecological sources,integrated the importance of multiple ecosystem services,calculated the ecological space network based on the minimum cumulative resistance model,integrated ecological networks and regional ecological texture,and realized the construction of the ecological security pattern of Tangshan City,and finally proposed ecological space management and control requirements based on the ecological security pattern.The results showed that an ecological security pattern based on ecological texture,integrating ecological sources and ecological corridors,formed a regional ecological network system,effectively improved the connectivity between ecosystems,and promoted the flow of ecological substances and energy.Integrating various ecological service function evaluations and applying them to the construction of resistance surfaces and ecological corridor extraction,and combining the key ecological protection and restoration needs of Tangshan City,the water ecological safety of the current river and lake water bodies and riparian zones,and the future development needs,a two-level ecological corridor system was constructed to enhance the connectivity of ecological corridors.This study solves the problem that the function of ecological source land points to the status quo rather than planning-oriented,and provides decision support for other bottom map territorial spatial planning.
