摘　　要：本研究基于形态学空间格局分析(MSPA)方法,以攸县为例,通过不同空间分辨率构建县域尺度森林生态格局,筛选森林生态源地,分析景观连通性特征。结果表明:攸县森林资源丰富,森林景观构成以大型斑块为主且分布集中连片;不同空间分辨率影响全县核心区景观连通性,空间分辨率越小,对周边核心区斑块的连通程度越为严苛和精准;10 m×10 m空间分辨率分析县域尺度较为适宜。This article was based on the Morphological Spatial Pattern Analysis(MSPA)method,taking Youxian as an example,to construct a county-level forest ecological pattern through different spatial resolutions,screened forest ecological source areas,and analyzed landscape connectivity characteristics.The results show that Youxian has abundant forest resources,and the forest landscape is mainly composed of large patches with concentrated and contiguous distribution;Different spatial resolutions have an impact on the landscape connectivity of the core area of the entire county.The smaller the spatial resolution,the more stringent and accurate the connectivity of the surrounding core area patches;The spatial resolution analysis of 10 m x 10 m is more suitable for the county scale.

关 键 词：森林生态网络 县域 空间分辨率 形态学空间格局分析
