神农架林区生态旅游生态安全的空间差异及其驱动因素

Spatial Differences and Driving Factors of Eco-tourism Ecological Security in Shennongjia Forest Area

基于DPSIR模型和脆弱性评估方法,运用分析网络过程(ANP)模型和K-means聚类方法,构建了适用于神农架的EES评估指标体系,包括驱动力、压力、状态、影响和响应5个类别59个指标,对神农架林区的EES状况进行了评估和分析。结果表明,神农架林区的EES指数在0.281~0.357,呈现出显著的空间分布特征,东部高于西部,南部低于北部,沿着湖北和重庆的边界呈现出梯度变化。影响EES状况有效的指标是物理和经济活动、生物多样性损失和生物多样性保护,反映了神农架林区的生态旅游业与生态系统之间的协调与冲突,以及生态旅游业对生态系统的影响与适应。

Based on DPSIR model and vulnerability assessment method,this paper uses ANP model and K-means clustering method to build an EES evaluation index system suitable for Shennongjia,including 59 indicators in five categories:driving force,pressure,state,impact and response.The EES status of Shennongjia forest area was evaluated and analyzed.The results showed that the EES index of Shennongjia forest area was between 0.281 and 0.357,showing a significant spatial distribution,higher in the east than in the west,lower in the south than in the north,and a gradient variation along the border of Hubei and Chongqing.The most effective indicators affecting EES status are physical and economic activities,biodiversity loss and biodiversity conservation,which reflect the coordination and conflict between eco-tourism and ecosystem,as well as the impact and adaptation of eco-tourism on ecosystem in Shennongjia forest region.
