摘　　要：目的明确宝鸡市秦岭生物多样性保护网络格局,补充与厘清生物多样性保护关键“热点”,为秦岭生态环境保护、生物多样性保护区划和重要生态修复工程建设提供有效参考。方法采用GAP分析法和最短路径分析法识别宝鸡市秦岭生物多样性保护区域。结果在ArcGIS软件的支持下,得出了现有的生物多样性保护网络格局和研究区的“空白点”,亦即“待保护点”。结论(1)陈仓区、岐山县的生态安全关键区比例在5%以下,需要较大程度地加强生物多样性保护,建立生态安全关键区,并提高生态网络的连接度;(2)凤县的生态安全关键区的比例在6%左右,需在小范围内进行生物多样性保护,如加强生态环境建设;(3)太白县和渭滨区的生态安全关键区比例在50%以下,可以对现有生态资源进行恢复性扩展;(4)眉县的生态安全关键区比例最高,应加强巡逻,避免被破坏。Purposes—To clarify the biodiversity protection network pattern of Qinling Mountain in Baoji City,supplement and make clear the key"hot spots"of biodiversity protection,and provide effective reference for Qinling ecological environment protection,biodiversity protection zoning and important ecological restoration projects.Methods—GAP analysis and shortest path analysis were used to identify the biodiversity conservation area of Qinling Mountain in Baoji City.Results—Aided by ArcGIS software,the existing biodiversity conservation network pattern and the"blank point"of the study area were obtained,which is the"point to be protected"discussed herein.Conclusions—(1)Ten proportion of key ecological security areas in Chencang District and Qishan County is less than 5%.It is necessary to strengthen biodiversity protection,establish key ecological security areas and improve the connectivity of ecological network.(2)The proportion of key ecological security areas in Fengxian County is about 6%,small-scale biodiversity protection is requireed for instance,the ecological environment construction shall be strengthened.(3)The proportion of key ecological security areas in Taibai County and Weibin District is below 50%,the existing ecological resources can be restored and expanded.(4)The proportion of key ecological security areas in Mei County is the highest.Patrol shall be strengthened to avoid damage.
