基于“三生”空间的土地利用冲突时空演变特征研究——以厦门、漳州和泉州城市群为例

Evolution of Spatio-temporal Characteristics of Land Use Conflict Based on Productional-living-ecological Space——A Case Study at Xiamen-Zhangzhou-Quanzhou Urban Agglomeration

[目的]研究“三生”空间冲突水平测度,为中小城市群土地利用空间冲突管理和优化调控提供参考。[方法]以厦门、漳州市和泉州市(以下简称“厦漳泉”)城市群2000,2010,2020年3期遥感影像数据为基础提取土地利用信息,从景观生态学角度构建土地利用空间冲突评价指标体系并定量测算,分析其时空演变特征。[结果](1)2000—2020年厦漳泉城市群三生用地类型以生态生产用地为主导,生活生产用地面积逐年保持增长且扩张速度最快。(2)20年间厦漳泉城市群整体处于中等空间冲突级别,空间冲突逐渐加剧,强冲突空间在三大城市中心城区及周边表现明显。(3)土地利用空间冲突全局Moran’s I指数检验结果高度显著,空间冲突集聚效应增强,局部空间的高高集聚和低低集聚空间集聚特征表现明显,低高集聚和高低集聚表现不明显,但内部空间关系基本稳定。[结论] 2000—2020年厦漳泉城市群空间冲突强度整体加剧,应加强分区管控和健全冲突风险预警机制。

[Objective] The productional-living-ecological space conflict was analyzed in order to provide a reference for the management and optimization of land use spatial conflict in small and medium-sized urban agglomerations.[Methods] Land use information was extracted from remote sensing image data for the Xiamen-Zhangzhou-Quanzhou urban agglomeration in 2000,2010,and 2020.A spatial conflict evaluation index system was constructed to quantify land use conflict from the perspective of landscape ecology,and temporal and spatial evolution characteristics were determined.[Results](1) Ecological production land dominated the Xiamen-Zhangzhou-Quanzhou urban agglomeration,and the area of living and production land increased over time.The increase rate was fastest from 2000 to 2020;(2) In general,the Xiamen-Zhangzhou-Quanzhou urban agglomeration exhibited a medium level of spatial conflict during the past 20 years,and spatial conflict had gradually intensified over time.A strong conflict space was evident in the central urban areas and areas surrounding the three major cities;(3) The overall Moran’s I index result for land use spatial conflict was highly significant,and the spatial conflict agglomeration effect was enhanced,while the local characteristics of spatial conflict showed obvious high-high agglomeration and low-low spatial agglomeration characteristics.Low-high agglomeration and high-low agglomeration were not obvious,but the internal spatial relationship was basically stable.[Conclusion] The intensity of spatial conflicts has intensified over time.Therefore,people should strengthen regional control and early warning mechanisms of conflict risk.
