英文摘要 【Objective】 To respond to the ecological conservation pressure brought by economic development, enhance the stability and spatial connectivity of ecosystems in Tiantai County, promote the coordinated development of ecological source protection, ecological corridor construction, and spatial regulation, mitigate landscape fragmentation, and foster balanced, organized and sustainable urban-rural ecological space development. 【Method】 With Tiantai County as a case study, the study combines the MSPA and the circuit theory to form the ecological network construction method and identifies the core ecological sources using the MSPA under the framework of source classification-corridor optimization-node restoration, which are then ranked in terms of importance using the dPC index. A comprehensive resistance surface is constructed based on six factors including terrain, vegetation and human activities, and ecological corridors are extracted with the key ecological nodes identified using the circuit theory. Results are verified through overlay and compared with current networks to verify the rationality of the planning. 【Result】 The study identifies 30 ecological sources (130.71 km² at core areas, mainly in the southwest), 67 ecological corridors (including 45 key corridors totaling 86.59 km), and 17ecological nodes (including 12 key nodes located around reservoirs and streams). The ecological sources and potential ecological corridors are distributed in most parts of the study area, while important nodes are mostly located in the construction land of the county. 【Conclusion】 Tiantai County has a favorable ecological condition for building an efficient ecological network. However, the overlap of water systems and urban development disrupts ecological processes and weakens landscape connectivity. Constructing a scientifically grounded network can mitigate spatial fragmentation and enhance the stability and functional connectivity of ecosystems. It is recommended to strengthen the protection of major river corridors and restore ecological connectivity to improve the resilience of the regional ecological security pattern.
