摘　　要：生态空间的合理划设是科学构建生态安全格局的重要基础之一。以福建省县级市武夷山市为研究区域,在生态系统服务重要性评价和生态敏感性评价的基础上,划设了武夷山市的禁止开发区、限制开发区和一般开发区,面积分别为1079.71、1267.22和375.35 km^(2),各占全市总面积的39.7%、46.6%和13.8%。整合空间分区结果,结合现有的自然保护地,使用最小阻力模型构建了武夷山市生态安全格局。结果表明:武夷山市识别了生态源地总面积1322.22 km^(2),占全市总面积的47.3%;确定了生态廊道755 km、生态节点55个;划分了高、中和低3种生态安全水平格局,面积分别为904.89、511.09和1392.15 km^(2),各占研究区面积的32.2%、49.6%和18.2%。研究结果为武夷山市的国土空间合理管控提供了依据。The rational allocation of ecological space is one of the important bases for constructing ecological security. Taking Wuyishan City, a county-level city in Fujian Province, as the study area, we delimited the forbidden development zone, restricted development zone and general development zone based on ecosystem service importance assessment and ecological sensitivity assessment. The three types of zones covered 1079.71, 1267.22, and 375.35 km^(2) respectively, accounting for 39.7%, 46.6%, and 13.8% of the total area of the city, respectively. Integrating the results of spatial zoning, combined with the existing natural protection area in Wuyishan City, the Minimum Cumulative Resistance model was used to construct the ecological security pattern. The area of ecological sources was identified as 1322.22 km^(2), accounting for 47.3% of the total area of Wuyishan City. A total of 755 km ecological corridors and 55 ecological nodes were determined. Three ecological security level patterns were classified, which were 904.89, 511.09 and 1392.15 km^(2) respectively, accounting for 32.2%, 49.6% and 18.2% of the study area, respectively. Our results provide a basis for the rational control of territorial space of Wuyishan City.
