| 摘 要： | 科学有效掌握国土空间时空演变特征及其驱动机制是优化与构建国土空间保护开发格局的基本前提。该研究以黄河三角洲为例,围绕"过程-格局-驱动"的逻辑主线,基于2000、2010和2020年遥感数据构建国土空间分类体系,利用弦图可视化模型和地学信息图谱刻画国土空间演变过程,借助重心偏移模型和空间自相关分析法明晰国土空间演变的时空格局特征,通过地理探测器解析国土空间演变的驱动机制。结果表明:1)2000—2020年黄河三角洲国土空间规模与结构变化日益显著,不同类型之间发生着农业空间内部互换、生态空间与农业空间互换以及城镇空间向生态空间的转移过程。2)2000—2020年黄河三角洲不同类型国土空间重心偏移呈同向连续和异向迂回现象,沿海地区的HH集聚和LL集聚特征显著,并在不同时期表现为农业空间和城镇空间占用生态空间转向城镇空间反哺生态空间和农业空间的特点。3)2000—2020年黄河三角洲前后两个时期国土空间演变的驱动力存在差异,由早期的交通区位和经济发展水平为主控因子逐渐转向后期以政策制度环境为主导的驱动机制。积极开展黄河三角洲资源环境承载能力和国土空间开发适宜性评价,构建合理有序的国土空间保护开发秩序是实现该地区可持续发展的重要支撑。

| Abstract: | Abstract: Territorial space is an essential carrier to support the sustainable development of ecological civilization in the human community. It is necessary to accurately identify the types of territorial space, and thereby to determine the temporal and spatial evolution characteristics and driving factors. Taking the High-Efficiency Eco-economic Zone of the Yellow River Delta as the research area, this study aims to optimize the pattern of land and space under the guideline of "process-pattern-drive". Firstly, a territorial space classification system was constructed using the remote sensing data from 2000 to 2020. Secondly, a chord diagram model in visualization data and Geo-information Tupu were selected to describe the evolution of territorial space. A gravity-center shift model and spatial autocorrelation were used to clarify the spatial and temporal pattern in territorial space evolution. Finally, a geographic detector was used to analyze the driving mechanism of territorial space evolution. The results show that: 1) The change rates of territorial space in the Yellow River Delta were 0.39% and 2.1% in 2000-2010 and 2010-2020, respectively. There was an increasingly significant change in the territorial space structure. The territorial space evolution included the internal exchange of agricultural space, the exchange of ecological space and agricultural space, as well as the transfer of urban space to ecological space. 2) The gravity-center of ecological space shifted 23.903 km to the southeast in the Yellow River Delta, indicating the longest migration path from 2000 to 2020. Nevertheless, the gravity center of agricultural space shifted 3.241km to the northwest with the shortest migration path. In addition, the spatial agglomeration of territorial space change was mainly concentrated in the coastal areas. The agricultural and urban space occupied the ecological space from 2000 to 2010, whereas, the urban space fed back ecological and agricultural space from 2010 to 2020. 3) There were different driving factors for the spatial differentiation in the spatial change rate in various periods. Specifically, the policy and institutional environment dominated the study area after the construction of the high efficiency eco-economic zone, whereas, the traffic location and the level of economic development dominated before that. A reasonable and orderly pattern of land protection was also established to evaluate regional resources, environment carrying capacity, and territorial space suitability ("double assessment"), thereby clarifying the carrying scale and suitability level of regional development for the decision-making on the territorial space strategies. |
