Based on the the ecological footprint model, this paper analyze the characteristics of natural capital utilization and comprehensive ecological security situation in CPUA from 2010 to 2021. The weighted Voronoi diagram was used for ecological security zoning, and partial least squares regression was employed to identify the main driving factors. The results revealed that: (1) the per capita ecological footprint (ef) of CPUA increased by 11.27%, while the per capita ecological carrying capacity (ec) remained relatively stable. The per capita ecological footprint size (EF_size) ranged from 0.289~0.300hm²/cap, whereas the ecological footprint depth (EF_depth) ranged between 2.595~2.928 and maintain an upward trend. (2) The ecological pressure index, ecological coordination index, stock-flow usage ratio, and ecological footprint diversity index demonstrated a gradual decline in ecological security situation. The improvement of ecological utilization efficiency contained the trend of ecological deterioration effectively. The comprehensive ecological security index was generally in a "medium insecurity" state. (3) Based on the weighted Voronoi diagram, the CPUA was divided into central core development zone, western transformation development zone, northern optimization development zone, eastern protection development zone, and southern green development zone. (4) The proportion of primary industry output value and the total energy consumption were important positive driving factors in most regions, while the influence of other factors on ecological security varied significantly in different regions.

基于生态足迹模型，分析了2010~2021年中原城市群自然资本利用特征和综合生态安全状况．运用加权Voronoi图进行生态安全分区，并利用偏最小二乘回归法分析主要驱动因素．结果表明：（1）中原城市群人均生态足迹不断增加（增幅11.27%），人均生态承载力相对稳定．人均生态足迹广度分布在0.289~0.300hm²/人之间，生态足迹深度分布在2.595~2.928之间且呈上升趋势．（2）生态压力指数、生态协调指数、存量流量利用比、生态足迹多样性指数表明生态安全状况逐渐恶化，生态利用效率的提高有效遏制生态恶化趋势，综合生态安全指数总体处于“中度不安全”状态．（3）基于加权Voronoi图将中原城市群划分为中部核心发展区、西部转型发展区、北部优化发展区、东部保护发展区和南部绿色发展区．（4）第一产业产值占比和能源消费总量在大多地区属于重要的正向驱动因素，其他因素在不同地区对生态安全的影响程度存在明显差异．
