摘　　要：为探究郑州市土地利用时空演变及其背后驱动力,本文采用地理探测器分析郑州市近20年土地利用时空格局演变特征及用地变化驱动机制,结果表明,郑州市耕地呈现逐年缩减趋势,建设用地呈现逐年增加趋势,其他用地类型则平稳发展;郑州市土地利用受地形、气候等自然因子及社会产值、人口密度等人为因子共同作用,人为因子的影响力逐渐增强。研究结果可为协调郑州市经济发展与土地利用合理规划提供定性、定量的支持,对缓解郑州市日益突出的人地矛盾,改善土地资源优化配置及实现生态环境的持续改善具有一定意义。In order to explore the spatiotemporal evolution of land use in Zhengzhou city and the driving force behind it,this paper uses geographical detectors to analyze the spatiotemporal pattern evolution characteristics of land use in Zhengzhou city in the past 20 years and the driving mechanism of land use change.The results show that the cultivated land in Zhengzhou city is decreasing year by year,the construction land is increasing year by year,and other types of land are developing steadily.The land use in Zhengzhou city is influenced by natural factors such as terrain and climate,as well as human factors such as social output value and population density,and the influence of human factors is gradually increasing.The research results can provide qualitative and quantitative support for coordinating the economic development and rational land use planning of Zhengzhou city,and have certain significance for alleviating the increasingly prominent contradiction between people and land in Zhengzhou city,improving the optimal allocation of land resources and realizing the continuous improvement of ecological environment.
