摘　　要：以基于形态学空间格局分析法(MSPA)和景观连通性指数识别确定生态核心区斑块,通过最小累积阻力模型(MCR)创建生态源地间的连接廊道,并且根据电路理论识别连接廊道中的生态夹点,由生态源地、生态廊道和生态夹点共同构建赣州市绿色基础设施网络。结果表明,MSPA能够依靠土地利用数据将研究区分成不同景观功能的景观要素类型,基于Conefor软件计算的各斑块的斑块重要性指数可以有效地筛选出重要的核心斑块作为生态源地,使生态源地的识别更符合景观生态学意义。最终筛选出共12个生态源地,总面积1421307.54 hm^(2),生成生态廊道25条。结合景观学和电路理论,以GIS平台为基础构建的绿色基础设施网络能够为赣州市绿色基础设施完善、物种多样性保护与生态空间合理规划提供科学依据。The patches in the ecological core area were identified based on morphological spatial pattern analysis(MSPA)and landscape connectivity index,and the connecting corridors between ecological sources were created through the minimum cumulative resistance model(MCR).The ecological pinch points in the connecting corridors were identified according to the circuit theory,and the green infrastructure network of Ganzhou City was constructed by ecological sources,ecological corridors and ecological pinch points.The results showed that MSPA analysis method could divide the research into landscape elements with different landscape functions based on land use data,the patch importance index of each patch calculated by Conefor software could effectively screen out the important core patches as ecological sources,which made the identification of ecological sources more consistent with the significance of landscape ecology.Finally,a total of 12 ecological sources were screened,with a total area of 1421307.54 hm^(2),and 25 ecological corridors were generated.Combining landscape science and circuit theory,the green infrastructure network constructed based on GIS platform can provide scientific basis for improving green infrastructure,protecting species diversity and rational planning of ecological space in Ganzhou City.
