摘要
生态承载力的研究是可持续发展这一国家战略的基础和内涵。选取2005-2021年中国林业制造业生态承载力有关数据,采用PSIR模型选取初始指标,通过内部一致性检验、KMO和Bartlett球形度对初始指标进行筛选,并使用因子分析法和熵值法计算各指标权重。得出逐年评估指数,考察林业制造业生态承载力影响因素随时间的演变轨迹。结果表明:2017年得分0.1418最高,社会经济和产业发展压力对得分影响最大。
The study of ecological carrying capacity is the foundation and connotation of the national strategy of sustainable development.The ecological carrying capacity of China's forestry manufacturing industry from^(2)005 to 2021 was selected;the initial index was selected by PSIR model;the initial index was screened by internal consistency test;KMO and Bartlett sphericity,and the weight of each index was calculated by factor analysis and entropy method.Finally,an annual evaluation index is obtained to examine the evolution trajectory of"influencing factors of ecological carrying capacity of forestry manufacturing industry"over time.The results showed that the highest score was 0.1418 in 2017,and the socio-economic and industrial development pressure had the greatest impact on the score.
