摘要: 自然资源空间管制是平衡生态保护和经济发展关系的基本工具,严守生态安全格局的底线思维对于重建系统完备、生态盈余的自然资源空间管制新格局具有重要指导意义。以胶东半岛典型山地丘陵区——栖霞市为例,应用数据密集型知识挖掘,集成地理信息方法与模型,基于栅格从生态服务功能重要性和生态环境敏感性两方面精准识别生态源地,利用地形位指数修正基本阻力面,并运用最小累积阻力模型提取生态廊道,从而构建生态安全格局,实现自然资源分区管制。结果表明:栖霞市生态源地面积为627.80 km2,占全市总面积的31.14%,集中分布在中东、中南和西北部,且超过一半源地为林地;关键、优化生态廊道各237.19 km、83.90 km,大多由林地组成,主要分布在中东、西北和西南部,形成完整的生态网络;划定禁止建设区、限制建设区、条件建设区和优先建设区,为自然资源空间精准管制提供方法保障。

Abstract: Space control of natural resources is the basic tool for balancing the relationship between ecological protection and economic development. Observing the bottom line of ecological security pattern strictly is of great guiding significance to reconstruct the new pattern of natural resources spatial control with complete system and ecological surplus. Taking Qixia city, an mountainous intensive agricultural area in Jiaodong Peninsula, as a case study area, coupling pattern and process, integrating geographic information method and model, this paper identified the ecological sources from the aspects of ecosystem service function importance and ecological environment sensitivity. Then the basic ecological resistance surface based on land cover and anthropogenic disturbance was revised by the terrain niche index, and the ecological corridors were identified using the minimum cumulative resistance model, so as to construct the ecological security pattern and achieve natural resources zoning control for Qixia city. The results showed that the ecological sources of Qixia city were 627.80 km2, accounting for 31.14% of the total area, mainly distributed in the central eastern, the central southern and the northwestern regions. More than half of the ecological sources were forest land. The key and optimized ecological corridors were 237.19 km and 83.90 km, mostly composed of forest land, mainly distributed in the central eastern, the northwest and the southwest, forming a complete ecological network. Finally, prohibited, restricted, conditional and prioritized construction areas were delineated. This provided method guarantee for precise control of natural resources space.
