【摘要】 为了调查加查峡谷兽类及鸟类多样性，2019年12月至2021年3月，利用GIS将调查区域划分成0.5 km×0.5 km的网格，并布设了85台红外相机，每3–5个月回收一次数据。累计获得15270个相机工作日，采集可辨别鸟兽照片和视频65581份，独立有效探测6006次，野生兽类4目9科18种，鸟类6目16科46种。其中，国家I级重点保护野生动物7种，国家II级重点保护野生动物有19种，合计占野生物种总数的40.63%；被IUCN红色名录评估为濒危（EN）的2种，易危（VU）的4种，近危（NT）的6种，合计占野生物种总数的18.75%；被《中国脊椎动物红色名录》评估为极危（CR）的1种，濒危（EN）的5种，易危（VU）的5种，近危（NT）的8种，合计占野生物种总数的29.69%。相对多度指数较高的前5种兽类均为保护物种，为猕猴、白唇鹿、中华鬣羚、赤狐和岩羊，相对多度指数较高的前5种鸟类为灰腹噪鹛、白顶溪鸲、藏马鸡、白颈鸫和白喉红尾鸲。人类在位于非保护地的加查峡谷活动探测率高、分布广；干扰总体上呈现出沿着S306省道及山谷分布。该峡谷虽位于非保护地且面临较强人为干扰，但仍维系了具有重要保护价值的野生动物群落。因此，建议相关部门应加强该地区的保护管理，以保护这里众多的稀有和濒危物种。更多还原

【Abstract】 To investigate the diversity of mammals and birds in the Jiacha Canyon, the study area was divided into 0.5 km × 0.5 km grids using GIS between December 2019 and March 2021, and 85 infrared cameras were deployed, with data collected every 3 – 5 months. A total of 15,270 camera-trap days were recorded, yielding 65,581 identifiable photos and videos of birds and mammals, with 6,006 valid detections. The data included18 species across 9 families in 4 orders of wild mammals, and 46 species across 16 families in 6 orders of birds. Among them, there are 7 species of wildlife under Class I national protection and 19 species under Class II national protection, together accounting for 40.63% of the total number of wildlife species recorded. According to the IUCN Red List of Threatened Species, 2 species were listed as Endangered(EN), 4 as Vulnerable(VU), and 6 as Near Threatened(NT), together accounting for18.75% of the total number of the recorded species. Based on the?Red List of China’s Vertebrates, 1 species was classified as Critically Endangered(CR), 5 as Endangered(EN), 5 as Vulnerable(VU), and 8 as Near Threatened(NT), together accounting for 29.69% of the total number of the recorded species. The top five mammal species with the highest relative abundance indices are all protected species: Macaca mulatta, Przewalskium albirostris, Capricornis milneedwardsii, Vulpes vulpes, and Pseudois nayaur. The top five bird species with the highest relative abundance indices are Trochalopteron henrici, Phoenicurus leucocephalus, Crossoptilon harmani, Turdus albocinctus, and Phoenicurus schisticeps. The findings show that the Jiacha Canyon has high species diversity with many rare and endangered species. Human activity in the Jiacha Canyon, located outside protected area, is both widespread and frequent; disturbances are generally concentrated along Provincial Highway S306 and throughout the valleys. The canyon still continues to support wildlife communities of significant conservation value, which have persisted despite substantial human disturbance in the area. Accordingly, it is recommended that relevant authorities strengthen conservation and management efforts in this area to protect its numerous rare and endangered species.更多还原
