    摘要:

    [目的] 构建具有城市特色的生态安全格局,以期为山东省济南市实现生态环境的保护与修复,以及区域协调发展提供思路,并为构建“山水林田湖草泉”一体的城市特色生态安全格局提供参考。[方法] 以济南市为研究对象,基于InVEST对生境质量进行评价,进而从“蓝—绿—泉”3个角度识别生态源地,并基于自然地理、人为干扰活动两个方面构建阻力面,最后使用最小累积阻力模型(MCR)识别生态廊道构建生态安全格局。[结果] 济南市生态源地面积为1 249.32 km2,占总面积的12.20%;生态阻力面呈现“中间高,南北低,多团块”的特点;研究区共有生态廊道119条,总长1 395.37 km,形成南连泰山北通黄河的“山河通廊”;济南市高、中、低生态安全缓冲区占总面积的40.41%,构建了“一带、三区、两翼、九点、多廊”的生态安全格局。[结论] 济南市生态源地主要分散于南部山区,纵横交错的河流起到了沟通物质能量信息的天然廊道作用。

    Abstract:

    [Objective] An ecological security pattern with urban characteristics was constructed in order to provide ideas for regional coordinated development of ecological environment protection and restoration of Ji’nan City, Shandong Province, and to provide references for constructing an urban characteristic ecological security pattern for a mountain-water-forest-farmland-lake-grass-spring system. [Methods] Habitat quality was evaluated for Ji’nan City based on the InVEST model, and the ecological sources were identified from the three perspectives of blue-green-spring. A resistance surface was subsequently constructed based on the natural geographical conditions and human disturbance. Finally, the ecological corridors were identified and the ecological security pattern was constructed using the minimum cumulative resistance model (MCR). [Results] The area of the ecological sources in Ji’nan City was 1 249.32 km2, accounting for 12.20% of the total area. The ecological resistance surface presented the characteristics of “high in the middle, low in the north and south, and many clusters”. 119 ecological corridors with a total length of 1 395.37 km were identified, and formed a mountain-river corridor connecting Mount Taishan in the south and the Yellow River in the north. The area of the high, medium, and low ecological security buffer zones in Ji’nan City accounted for 40.41% of the total area, and an ecological security pattern of “one belt, three zones, two wings, nine points, and multiple corridors” was constructed. [Conclusion] The ecological source areas of Ji’nan City are mainly scattered in the southern mountainous areas. The crisscrossing rivers serve as natural corridors for communicating material and energy information.
