摘　　要：研究以黄河三角洲19县(市、区)为例,首先基于POI数据、核密度分析等方法测度了2019年该区域土地利用水平,其次基于综合指数法构建土地生态安全评价模型,最后采用耦合协调度模型等,探讨两者间的空间耦合特征。研究表明:2019年黄河三角洲土地利用水平与土地生态安全的空间耦合呈“大集聚、小分散”的空间分布特征,耦合协调类型以轻度失调和濒临失调为主;2019年黄河三角洲土地利用水平与土地生态安全存在显著的空间负相关性,LH集聚效应分布于“黄三角”东部,HH集聚效应存在于核心城区,西部地区HL集聚特征显著。With 19 counties(municipalities and districts) of the Yellow River Delta as an example, this study firstly measures the land use level in the region in 2019 based on POI data and nuclear density analysis, then constructs a land ecological security evaluation model based on the comprehensive index method, and finally explores the spatial coupling characteristics between the two factors by adopting the coupling coordination degree model. The research findings show that the spatial coupling between the land use level and land ecological security in the Yellow River Delta in 2019 presents the spatial distribution characteristics of “large agglomeration and small dispersion”, and the coupling coordination type is mainly mild imbalance and near imbalance;and that in 2019, there existed a significant spatial negative correlation between the land use level and land ecological security in the Yellow River Delta with the LH agglomeration effect distributing in the east area of the Yellow River Delta, the HH agglomeration effect existing in the core urban area and significant HL agglomeration characteristics existing in the west area.
