摘　　要：生态安全格局是区域生态环境良好发展的重要基础,有利于维持生态过程、保护生态环境、引导城镇空间扩展以及景观规划建设。以浮梁县为研究区,运用形态学空间格局分析(Morphological spatial pattern analysis,MSPA)、最小累积阻力模型(Minimal cumulative resistance,MCR)以及其他景观生态学评价与统计方法,构建“源地-阻力-廊道-节点”模式的生态安全格局。结果显示:(1)生态源地主要分布在西北部和东部,包括山地森林、自然保护区以及生态风景区;(2)整体生态阻力值较低,高综合阻力值区域呈网状分布,最小累积阻力值较高的区域位于南部人口聚集区域;(3)中部生态廊道的密度较高,其景观类型以林地、耕地、草地为主。总体生态安全水平良好,但生境斑块内外联系较弱,期望通过构建生态安全格局推动浮梁县的生境改善和景观建设。Ecological security pattern is an important basis for the good development of regional ecological environment,which is conducive to maintaining ecological process,protecting ecological environment,guiding urban space expansion and landscape planning and construction.Taking Fuliang County as the research area,Using Morphological spatial pattern analysis(MSPA),Minimal cumulative resistance(MCR)model and other landscape ecology evaluation and statistical methods to construct the ecological security pattern of"source-resistance-corridor-node"mode.The results showed that:(1)The ecological sources were mainly distributed in the northwest and east,including mountain forests,nature reserves and ecological scenic spots;(2)The overall ecological resistance value was low,the area with high comprehensive resistance value showed a network distribution,and the area with high minimum cumulative resistance value was located in the southern population aggregation area.(3)The density of the central ecological corridor was high,and its landscape types were mainly woodland,arable land and grassland.The overall ecological security level was good,but the connection between the inside and outside of the habitat patch was weak.The ecological security pattern was expected to promote the habitat improvement and landscape construction of Fuliang County.
