摘　　要：公益林是森林资源的精华和主体,是生态文明建设的重要载体。以广东省公益林为研究对象,基于PSR模型,结合广东省林地生态脆弱性评价结果,利用熵权法确定指标权重,构建广东省公益林生态承载力评价指标体系,对广东省公益林生态承载力等级分布格局进行分析。研究结果表明:广东省公益林生态系统整体处于较稳定状态,生态承载力等级以可载、适度可载、轻度超载为主,中度超载和重度超载区域主要分布在清远市、韶关市、肇庆市。综合评价广东省公益林生态承载力等级,掌握广东省公益林生态承载力的空间分布特征,以期为广东省公益林布局优化、森林资源保护和林业高质量发展提供理论支持。Public welfare forest is the essence and main body of forest resources and an important carrier of ecological civilization.Based on the PSR model and combined with the evaluation results of forest ecological vulnerability in Guangdong Province,we used the entropy weight method to determine the indicator weight,to construct an evaluation index system for the ecological carrying capacity of the public welfare forest in Guangdong Province.The distribution pattern of ecological carrying capacity levels of the public welfare forest in Guangdong Province is analyzed.The results show that the Guangdong provincial public welfare forest ecosystem is in a relatively stable state.In total,public welfare forest in Guangdong could be divided into three ecological bearing capacity levels:loading,moderate loading,and mild overload.Divided by administrative divisions,the moderate overloaded and heavy overload areas are mainly distributed in Qingyuan,Shaoguan,and Zhaoqing.A comprehensive evaluation of the ecological carrying capacity and a better understanding of spatial distribution characteristics of the public welfare forest in Guangdong Province can provide theoretical support for optimizing the layout of public welfare forests,high-level protection of forest resources,and high-quality development of forestry.
