精细化识别城市土地利用类型与功能演替分析，揭示空间形态与社会功能的分布特征，为科学认知城市发展规律及优化国土空间规划管理提供理论支撑与实践指引。本研究以郑州市主城区为研究对象，整合遥感影像、POI数据和OSM路网数据，采用核密度函数、精细化识别规则对土地利用功能类型进行精准划分，结合多种空间统计方法与区位熵分析，探究2012—2022年城市各功能用地集聚扩散特征和功能演替规律。研究结果表明：①土地利用类型演变呈现显著分化与混合化特征，商业服务（简称商服）功能用地主导扩张，居住功能用地先增后减，工业与公共功能用地持续缩减，各类功能用地布局从边界清晰转向协同交错；②功能空间与建设用地扩张非同步，体现规划与经济增长的协同滞后效应；③功能重构呈差异化特征，商服集聚度最高且为多中心格局，复合功能街区呈西北—东南带状分布；④主导功能演替呈现专业化与复合化并行趋势。本研究为内陆中心城市土地精细化管控与空间优化提供科学依据。

This study takes the central urban area of Zhengzhou City as its research object, integrating remote sensing imagery, POI data, and OSM road network data. It employs kernel density functions and precise identification rules to accurately classify land use functional types, combining various spatial statistical methods and location entropy analysis to explore the aggregation and diffusion characteristics of urban functional land use and the patterns of functional succession from 2012 to 2022. The research findings indicate: 1) The evolution of land use types exhibits significant differentiation and hybridization characteristics. 2) There is a lack of synchrony between functional spatial expansion and construction land expansion. 3) The restructuring of functional spaces exhibits differentiated patterns of aggregation and dispersion. 4) The evolution of dominant functions reflects a parallel trend toward specialization and diversification.
