为深入了解秦岭北麓地区生态状况,利用高分遥感数据,借助模糊层次法构建生态安全演变评估模型,并结合时空变异及其驱动因子分析,探讨秦岭北麓的生态安全现状.研究发现:秦岭北麓地区的生态安全性整体呈增长趋势,生态安全中级以上区域面积占比从67.5％增长到71.9％;生态安全性在南部整体高于北部,并存在明显的地带性分布特征;生态安全演化呈先下降后增长的态势,其中土地利用、归一化植被指数和PM2.5被确认为主要的驱动因素,相关系数分别为0.90、0.86和0.79,说明城市化进程的人为活动和生态保护政策对秦岭北麓地区的生态安全性有显著影响.研究结果不仅为秦岭北麓地区的生态安全性提供了科学评估,还为区域生态保护与可持续发展策略制定提供了有力的决策支持.
Spatial temporal variability and driving factors of ecological security in the northern slope of Qinling Mountains
In order to further understand the ecological status of the northern slope of Qinling Mountains,high-resolution remote sensing data and fuzzy analytic hierarchy process method were used to build an assessment model for the evolution of ecological security.With the analysis of spatio temporal variation and its driving factors,the ecological security status of the mountains was deeply explored.The findings reveal an overall increasing trend in the ecological security of the region,with areas rated as moderately safe or above increasing from 67.5％to 71.9％.Eco-logical security is generally higher in the southern than in the northern regions,displaying a clear zonal distribution pattern.The evolution of ecological security first declined and then grew,with land use,normalized vegetation index,and PM2.5 identified as the primary driving factors,with correlation indices of 0.90,0.86,and 0.79,respectively.The results indicate that anthropogenic activities from urbanization and ecological conservation policies significantly influence the ecologi-cal security of the northern Qinling region.This study not only offers a scientific assessment of the ecological security in the mountains,but also provides robust decision-making support for re-gional ecological conservation and sustainable development strategies.
