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 (EFsize) ranged from 0.289~0.300hm2/cap, whereas the ecological footprint depth (EFdepth) 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.
