基于多功能适宜性的黄河三角洲国土空间潜在冲突特征与优化格局研究

Characteristics of potential conflicts of territorial space and optimization pattern in the Yellow River Delta based on multi-functional suitability

以黄河三角洲为例,利用社会生态系统理论构建多功能潜在冲突概念框架,从生态保护、农业生产与城镇建设3个方面开展国土空间多功能适宜性评价,借助多维度潜在冲突识别模型揭示国土空间多功能潜在冲突类型、强度及空间格局,基于潜在冲突调解机制重构国土空间保护与开发格局。结果表明:(1)黄河三角洲国土空间多功能适宜性表现出“生态保护重要、农业生产和城镇建设适宜”的特征。(2)黄河三角洲农业生产-城镇建设双功能型和生态保护-农业生产-城镇建设多功能型潜在冲突占据主导,冲突面积占比分别为84.12%和85.35%,冲突强度主要为重度和中度。(3)黄河三角洲国土空间多功能潜在冲突的空间分布在地理单元上呈现出显著的陆-河-海梯度分异特征,在行政单元上具有一定的非均衡性。(4)土地利用规划与土地利用现状在潜在冲突调解中发挥刚性约束与弹性引导效应,两者统筹作用下形成的国土空间优化格局是调节区域生态环境脆弱性和规范人类活动合理性的科学指南。

The identification and mediation of multi-functional potential conflicts in territorial space is an important basis for optimizing the pattern of territorial space and realizing high-quality development.In this paper,the Yellow River Delta is taken as the research area,and the social ecosystem theory is selected to establish conceptual framework of potential conflict of multi-function of territorial space.Then the multi-functional suitability evaluation of territorial space is carried out from three aspects of ecological protection,agricultural production and urban construction.The types,intensities and spatial patterns of multi-functional potential conflicts of territorial space in the Yellow River Delta are revealed by means of multi-dimensional potential conflict identification model.With the help of mediation mechanism of potential conflicts,the optimized pattern of territorial space in the Yellow River Delta is reconstructed.It is concluded that:1)The suitability of ecological protection,agricultural production and urban construction function in the Yellow River Delta are important,suitable,and suitable,respectively;2)The types of potential conflicts that the dual-functional type of agricultural production-urban construction and the multi-functional type of ecological protection-agricultural production-urban construction area proportion accounted for 84.12% and 85.35%,and their intensity are severe and moderate respectively,dominated potential conflicts types in the Yellow River Delta;3)The spatial distribution of multi-functional potential conflicts of territorial space in the Yellow River Delta shows a significant land-river-sea gradient differentiation in the geographical unit,and has a certain degree of imbalance in the administrative unit;4)Land use planning and land use status play a rigid constraint and flexible guiding effect in the mediation of potential conflicts.The optimized pattern of territorial space formed under the coordination of the two is a scientific guide to regulate the ecological environment vulnerability and regulate the rationality of human activities in the Yellow River Delta.
