神农架国家公园生态韧性:演进特征、障碍因素及发展趋势

Ecological Resilience of Shennongjia National Park: Evolutionary Characteristics,Obstacles,and Development Trends

  • 摘要: 系统评价国家公园生态韧性对自然保护地体系的生态风险预防和生态安全维护意义重大。以DPSIR为框架构建国家公园生态韧性评价指标体系,采用熵权TOPSIS法测度神农架国家公园生态韧性综合指数及各准则层综合得分,运用障碍度模型分析生态韧性的阻碍因子,通过灰色预测模型判识生态韧性的未来发展趋势。结果表明,2004—2022年神农架国家公园生态韧性总体呈上升态势,特别在2014年及以后跃升更为明显。从准则层维度看,驱动层和响应层是生态韧性的核心障碍,压力层障碍度则最低;从因素层维度看,造林面积、财政科技支出、产业结构转型、人口自然增长率和林业总产值是生态韧性提升的关键制约因子。灰色预测结果表明,未来5年神农架国家公园生态韧性呈稳步上升态势,大体上延续2004—2022年的上升轨迹。以期为我国国家公园生态韧性综合评价提供借鉴参考,为推进我国国家公园治理体系和治理能力现代化提供启发和思路。

     

    Abstract: The systematic evaluation of the ecological resilience of a national park is of great significance to the ecological risk prevention and ecological security maintenance of the nature park system.The ecological resilience evaluation index system of national parks is constructed based on the framework of DPSIR,the entropy weight TOPSIS method is used to measure the ecological resilience of Shennongjia National Park and the composite scores of each criterion layer,the obstacle model is used to analyze the obstruction factors of ecological resilience,and the future development trend of ecological resilience is identified through the grey prediction model.The results show that the ecological resilience of Shennongjia National Park is generally increasing from2004 to 2022,especially in 2014 and later.From the dimension of the criterion layer,the driver layer and the response layer are the core barriers to ecological resilience,while the pressure layer has the lowest barrier;from the dimension of the factor layer,the afforestation area,financial and scientific and technological expenditures,the transformation of the industrial structure,the natural growth rate of the population,and the total output value of the forestry industry are the key constraints on the enhancement of ecological resilience.The gray prediction results show that the ecological resilience of Shennongjia National Park is steadily increasing from 2023 to 2027,largely continuing the upward trajectory from 2004 to 2022.This paper aims to provide reference for the comprehensive evaluation of the ecological resilience of China’s national parks,and to provide inspiration and ideas for promoting the modernization of China’s national park governance system and governance capacity.
