摘要
林业生态安全是国家生态安全的重要组成部分,对区域可持续发展及生态文明建设发挥着重要作用。为克服现有林业生态安全评价中系统复杂性不足和指标体系缺乏验证的局限,文章基于对广义林业生态安全(FES)内涵、构成及作用机理的分析,考虑了现有研究尚未纳入的潜在因素,选择DPSIR理论构建FES指标框架,并结合结构方程模型(SEM),利用中国30个省份的面板数据,对FES指标框架进行统计检验和指标优化,最终得到了基于DPSIR-SEM的FES评价指标体系及权重。为进一步验证指标体系的合理性和实用性,对黑龙江省的生态安全做了实证分析,评判结果与已有研究及实际情况整体相符。
Forestry ecological security is an important part of national ecological security and plays an important role in regional sustainable development and ecological civilization construction. In order to overcome the limitations of insufficient system complexity and lack of verification on index systems in the existing forestry ecological security evaluation, based on the analysis of the connotation, composition and mechanism of the generalized forestry ecological security(FES), this paper considers the potential factors that have not been included in the existing studies, and selects DPSIR theory to construct FES index framework. And then, combining it with structural equation model(SEM), the paper uses the panel data of 30 provinces in China to conduct statistical test and index optimization on FES index framework, and finally obtains the FES evaluation index system and weights based on DPSIR-SEM. In order to further verify the rationality and practicality of the index system, the paper also empirically analyzes the ecological security of Heilongjiang Province, and the evaluation results are consistent with the existing researches and the actual situation on the whole.
