摘　　要：生态保护红线是区域内生态保护的核心区块,是国家和区域生态安全的重要保障,也是生态安全格局构建的关键组分。选取佳木斯市为研究区域,以生态保护红线为生态安全格局构建的生态源地,基于最小累积阻力模型构建了佳木斯市生态安全格局构建,划分了低、中、高3种水平的生态安全格局,并对生态源地开展景观连通性评估,确定了在生态廊道构建中的核心斑块,主要集中在北部的松花江、黑龙江及乌苏里江流域,以及南部的七星峰区域。Ecological protection redlines protect the core area of regional ecological protection.They are not only important guarantee of national and regional ecological security,but also key components of the construction of ecological security pattern.Here we chose Jiamusi City as the research area,and then selected the red line regions as sources of ecological security patterns and utilized the minimum cumulative resistance model to build comprehensive ecological security patterns.Therefore,three-level ecological function zones were recognized,which corresponded to ecological protection area and proposed construction countermeasures.In addition,we assessed the landscape connectivity of ecological sources within ecological security pattern,and then identified the core patches in the construction of ecological corridors,such as the ecological sources patches of Songhua River,Heilongjiang River and Wusuli River Basins in the North of Jiamusi City,and the ecological sources patches of Seven Star Peaks in the South of Jiamusi City.

关 键 词：生态保护红线 生态安全 生态源地 景观连通性
