摘　　要：基于景观生态安全格局优化理念,利用GIS技术和主成分分析方法,从增强生态系统的整体性和连通性的角度出发,优化研究区江西省高安市景观生态安全格局,以确定森林城市建设的3个关键要素,即生态源地、生态廊道和生态节点。结果表明,从影响研究区生态景观连通性的11个指标中提取了2个主成分,第一主成分为内聚力指数,第二主成分为连接性指数;在270 m粒度水平下生态景观连通性最稳定,尺度最适宜,为研究区生态源地参照粒度;研究区森林城市建设关键点包含59块生态源地、59条生态廊道、21个生态节点。Based on the concept of landscape ecological security pattern optimization, GIS technology and principal component analysis method was used to optimize the landscape ecological security pattern of the study area from the perspective of integrity and connectivity of the ecosystem, so as to determine the three key elements, namely, ecological sources, ecological corridors and ecological nodes. The results showed that two principal components were extracted from 11 indicators influencing the ecological landscape connectivity in the study area. The first principal component was named cohesion index; and the second principal component was named the connectivity index. The 270 m grain level, under which the ecological landscape was the most stable and the scale was the most suitable, was taken as the reference area. 59 ecological sources, 59 ecological corridors and 21 ecological nodes should be taken as the key points for the construction of forest city in the study area.
