山西省运城市位于黄河中下游三省交界处,其景观要素成分复杂,对运城景观生态网络斑块与廊道的研究有利于黄河生态系统稳定性的保护.基于形态空间格局理论(MSPA)确定连通性强的核心斑块,识别核心生态源地,以最小累计阻力模型(MCR)为基础,叠加7种阻力因子构建综合阻力面,根据重力模型划分生态廊道等级.以基于电路理论(CIRCUIT)的Linkage Mapper工具识别生态夹点和障碍点作为生态节点,综合构建源地(面)-廊道(线)-节点(点)的运城市景观生态网络.结果表明:1)运城市核心生态源地有9处,综合重力模型和实际建设需求划分13条重要生态廊道和10条一般生态廊道,识别出关键生态节点17个,一般生态节点34个;2)现有重要生态廊道集中于运城南部,南北方向生态联系较弱,可优先加强贯穿稷山县、新绛县、闻喜县的重要生态廊道建设;3)MSPA模型与电路理论的综合运用可提升景观生态网络构建的科学性和准确性,有利于确定生态修复关键区域,为生态修复项目的布局提供有力支撑.
Construction of Landscape Ecological Network in Yuncheng City of Shanxi Province Based on MSPA-MCR-CIRCUIT
Yuncheng City in Shanxi Province is located at the junction of three provinces in the middle and lower reaches of the Yellow River,and its landscape elements have complex components.The study of ecological network patches and corridors in Yuncheng City is conducive to the protection of the stability of the Yellow River ecosystem.In this study,core patches with strong connectivity were identified based on the Morphological Spatial Pattern Theory(MSPA)in order to recognize core ecological sources.The Minimum Cumulative Resistance Model(MCR)was used as the basis to construct a comprehensive resistance surface by superimposing seven resistance factors,and ecological corridors were divided into classes according to the gravity model.Ecological pinch points and barrier points were identified as ecological nodes by the Linkage Mapper tool based on the Circuit Theory.The ecological network of source(surface)-corridor(line)-node(point)in Yuncheng City was constructed.The results showed that:1)There were 9 core ecological source sites in Yuncheng City,13 important ecological corridors and 10 general ecological corridors were divided by the gravity model and actual construction demand,and 17 key ecological nodes and 34 general ecological nodes were identified.2)The existing important ecological corridors are concentrated in the south of Yuncheng,and the ecological connection in the north-south direction is weak,so the construction of important ecological corridors running through Jishan County,Xinjiang County and Wenxi County can be prioritized to increase.3)The comprehensive application of MSPA model and circuit theory can enhance the scientificity and accuracy of ecological network construction,which is conducive to identifying key ecological restoration areas,providing strong support for the layout of ecological restoration projects.
