This study aimed to uncover the spatiotemporal evolution and influencing factors of ecological resilience in Zhaoqing City. An evaluation index system was constructed based on data from 2000 to 2024, utilizing the comprehensive index method, obstacle degree model, and linear regression analysis. The findings revealed that the comprehensive ecological security index escalated from 0.214 3 to 0.629 0, marking an increase of 193.5%. This growth exhibited a three-stage pattern characterized by “slow rise, steady improvement, and rapid improvement”. The structure of ecological security transitioned from being pressure-dominated to response-dominated, with the proportion of the pressure index decreasing from 39.7% to 26.5%, and the response index proportion increasing from 27.5% to 41.6%. The obstacle degree of solid waste utilization rate diminished from 18.2% to 11.0%, and per capita carbon emissions reduced from 15.8% to 7.0%. However, the SO2 removal rate (16.0%) and soot removal rate (14.5%) emerged as the primary constraints, suggesting that the capacity for atmospheric pollutant removal is a critical bottleneck. Forest coverage was identified as the dominant factor regulating ecological resilience, accounting for 71% of the spatial variation. In contrast, temperature had a minimal effect, while precipitation and sunshine duration were not significant. This research provides a scientific foundation for the construction of ecological security and enhancement of resilience in Zhaoqing City and similar ecological function areas. |
