摘要
探究盆地城市的三生空间冲突现状及驱动机制,有利于促进盆地城市的人地关系的协调发展。以典型盆地城市城固县为研究对象,基于地理信息系统(GIS)技术,对2000—2020年中三个年份进行三生空间分类,利用三生空间冲突测度模型、地理探测器等方法,分析了2000—2020年三生空间的冲突时空演变规律及探究冲突演变的驱动机制。结果表明:研究区三生空间类型整体上呈现前期变化剧烈、后期趋缓的特征,类型变化以生产生态空间转出为主;冲突等级空间分布呈现“南高北低”格局,南部因生态与生产功能交错成为强冲突核心区,北部生态生产空间连片分布区域冲突程度较低;驱动机制探究显示研究区冲突演变受自然基底约束及人为干扰因素共同驱动,其中高程、坡度及交通道路是引起冲突变化的核心因素。研究结果可为盆地城市三生空间协调发展及国土空间优化提供科学依据。
Exploring the current status and driving mechanisms of spatial conflicts in the production-living-ecological(PLE)space of basin cities is beneficial for promoting the coordinated development of human-environment relationships.Taking Chenggu County,a typical basin city,as a case study,this research utilizes geographic information system(GIS)technology to classify the production-living-ecological space in 2000,2010,and 2020.Using models for measuring spatial conflicts in the production-living-ecological space and geographic detector methods,the study analyzes the temporal and spa⁃tial evolution of these conflicts from 2000 to 2020 and investigates the driving mechanisms behind these changes.The results show that the types of production-living-ecological spaces in the study area exhibit a characteristic of dramatic changes in the early stages,followed by a gradual slowdown in the later stages,with the primary change being the shift of productionecological space.The spatial distribution of conflict levels presents a“higher in the south,lower in the north”pattern,with the southern region becoming the core of intense conflict due to the overlap of ecological and production functions,while the northern region,where ecological and production spaces are distributed contiguously,experiences lower conflict levels.The analysis of driving mechanisms reveals that the evolution of conflicts in the study area is driven by both natural constraints and human interference,with elevation,slope,and transportation networks being the core factors contributing to the changes in conflicts.The research findings provide scientific guidance for the coordinated development of production-livingecological spaces in basin cities and the optimization of territorial space.
