摘要
通过样线调查和红外相机监测等方式,选取三江源地区共玉高速和S308省道2条典型公路的部分路段,开展沿线野生动物的分布情况研究.结果显示,共玉高速沿线分布的野生动物有兽类8种,鸟类35种,其中国家省级保护动物18种,占比41.86%,相对多度指数最高的为赭红尾鸲(1.59);S308沿线有兽类12种,鸟类8种,其中国家省级保护动物13种,占比65.00%,相对多度指数最高的为藏狐(5.81);2条道路桥涵中的大桥利用率均显著高于中小桥和涵洞,从通道利用率情况看,桥涵通道被利用主要出现在早晚2个高峰.
Abstract
We selected some sections of Gongyu Expressway and S308 Provincial Highway in Three-Rivers-Source region to study the distribu-tion of wild animals along the line through transect survey and infrared camera monitoring.The results showed that there were 8 species of beasts and 35 species of birds distributed along the Gongyu Expressway,including 18 species of national and provincial protected animals,accounting for 41.86%.The highest relative abundance index was Black redstart(1.59).There were 12 species of mammals and 8 species of birds along the S308 route,including 13 species of national and provincial-level protected animals,accounting for 65%.The highest relative abundance index was the Tibetan fox(5.81);the utilization rate of bridges and culverts on both roads was significantly higher than that of small and medium-sized bridges and culverts.From the perspective of channel utilization,the utilization of bridge and culvert channels mainly occurred during the morning and evening peaks.
