摘 要:在城市化背景下,生态系统受到来自人类社会日益严重的威胁,自然生态空间遭到破坏。对自然生态空间进行识别与管控可以更好地建设和保护国土空间生态资源,促进生态保护与社会经济耦合协同发展,保障区域的生态安全。融合多源数据及方法,从生态服务重要性和生态环境敏感性两方面评价和识别生态源地的空间范围;基于最小累积阻力模型(Minimum Cumulative Resistance, MCR)提取关键和优化生态廊道,系统化识别山东省自然生态空间并进行差异化管控。研究结果表明:山东省生态源地集中分布在鲁中山区和胶东半岛地区,总面积为21165.10 km^(2),关键生态廊道和优化生态廊道长度分别为1078.32、511.25 km,土地利用类型以耕地和林地为主,主要分布在鲁中山区和鲁北平原区,可形成联系紧密的生态网络。本研究将自然生态空间划分为生态源地、生态保育区、其它生态用地三种类型,根据不同空间类型提出具有针对性的分类管控措施,为自然生态空间的系统化识别与管控提供理论参考和方法保障,能够更好地实现省级国土空间规划的战略性、协调性目标。In the context of urbanization, the ecosystem is increasingly threatened by human society and the natural ecological space is destroyed. The identification and management of natural ecological space can better construct and protect the ecological resources of land and space, promote the coordinated development of ecological protection and socio-economic coupling, and ensure the ecological safety of the region. This study integrates multi-source data and methods, evaluates and identifies the spatial range of ecological sources from two aspects of the importance of ecological services and the sensitivity of ecological environment;extracts key and optimized ecological corridors based on the least cumulative resistance model, and systematically identifies the nature of ecological space and differentiated management and control in Shandong Province. The results show that the ecological sources of Shandong Province are concentrated in the central mountainous area and the Jiaodong Peninsula, with a total area of 21,165.10 km^(2). The lengths of key ecological corridors and the optimized ecological corridors are 1078.32 km and 511.25 km, respectively. The main land use types are the cultivated land and forest land, mainly distributed in the central mountainous area and northern plain area, which can form a closely connected ecological network. The research divides the natural ecological space into three types: ecological source area, ecological conservation area, and other ecological land. According to different space types, targeted classification management and control measures are proposed to provide theoretical references and methodological guarantees for the systematic identification and management of natural ecological spaces, which can better achieve the strategic and coordinated goals of provincial territorial space planning.
