基于响应面分析的西部生态环境安全多因素影响机制研究OA

Under the combined pressures of ecological degradation,climate variability,and governance constraints,ecological and environmental security in western China has become increasingly fragile,highlighting the urgent need to clarify the key driving factors and their synergistic mechanisms.To deepen understanding of the complex mechanisms underlying ecological and environmental security and enhance the relevance and implementability of policy formulation,this paper focuses on ecological security in western China.By integrating ecological governance,biodiversity conservation,climate response measures,and government policy support into a unified analytical framework,it systematically examines how different factor combinations and their matching patterns collectively influence ecological security.The research aims to reveal the comprehensive impact of multidimensional governance elements under nonlinear interactions on ecological security,as well as identify optimal allocation pathways for these elements.Furthermore,the paper employs response surface methodology,leveraging the principles of Box-Behnken experimental design and utilizing Design-Expert 13 software to construct a four-factor,three-level response surface analysis model.The empirical results indicate that all four factors exert significant positive impacts on ecological and environmental security,with ecological governance and government policy support demonstrating relatively stronger effects.Significant interaction effects are observed between ecological governance and biodiversity conservation,ecological governance and climate response measures,ecological governance and policy support,as well as between biodiversity conservation and climate response measures and policy support,revealing strong synergistic relationships among governance dimensions.Moreover,response surface optimization shows that ecological environmental security reaches its highest level when all factors are jointly maintained at high intensities,suggesting that coordinated multi-dimensional interventions are more effective than isolated policy actions.From a nonlinear coupling and synergy perspective,this study elucidates the formation mechanism and optimization pathways of ecological environmental security in western China.Since a single governance instrument is insufficient to effectively improve the level of ecological security,it is necessary to guide local governments and enterprises to form a multi-objective collaborative governance mechanism so as to enhance the overall efficiency of governance.
