陕西长青自然保护区大中型野生动物分布特征研究

Effects of Vegetation,Altitude and Slope Position on the Distribution of Large and Medium-sized Wildlife in Changqing National Nature Reserve

利用长青自然保护区华阳片区2012-2021年10条动物监测样线巡护监测数据,研究分析了该保护区大中型野生动物种类及其空间分布,植被、海拔、坡位等因素对大中型野生动物分布的影响。结果显示:该保护区共有大中型兽类和鸟类30种,其中Ⅰ级保护动物5种,Ⅱ级保护动物12种;针阔混交林中发现的物种种类最多,包括21种兽类和鸟类,其次是阔叶林;物种分布数量随着海拔升高而递减;下坡位分布兽类、鸟类最多(共21种),谷地物种分布最少(共9种)。

Based on the patrol and monitoring data of 10 animal monitoring transect lines in Huayang area of Changqing National Nature Reserve from 2012 to 2021,the effects of vegetation,altitude and slope position on the distribution of large and medium-sized wildlife were analyzed.The results showed:1)A total of 30 species of animals and birds were recorded from 10 transect lines,including 5 species under first class protection and 12 species under second-class protection;2)the largest number of species were found in the mixed confiers,including 21 kinds of animals and birds,followed by broad-leaved forest;3)on the whole,the number of species decreased with the increase of altitude,and mainly found in the altitude below 1600m;4)the lower position of slope had the largest distribution of animals and birds(21 species in total),while the bottom of the valley had the smallest distribution of species(9 species in total).
