为评估G7京新高速（巴里坤至梧桐大泉段）野生动物通道的穿越效果，自2023年3月12日至2025年6月11日，采用17台红外相机对12处动物通道开展持续监测。结果显示：所有动物通道都被野生动物利用，通道被利用的比例为 100%，即所有通道至少被野生动物通过一次；监测到6种兽类，其中5种为国家重点保护野生动物，鹅喉羚（Gazella subgutturosa）与狐狸（包括赤狐（Vulpes vulpes）和沙狐（Vulpes corsac））相对多度指数RAI最高，分别为101.50和36.07；鹅喉羚春秋两季的RAI最高、狐狸春、秋、冬季的RAI较高，鹅喉羚主要在白天，而狐狸主要在夜间，交通量的增加并不能显著限制两种动物对通道的利用；该路段设置的上跨式通道和下穿式通道对于兽类的穿越同等重要，目前没有发现这些兽类存在偏好性；兽类穿越动物通道与通道尺寸、栖息地因素的相关性不强，但与人为干扰呈显著正相关，说明只要动物通道位于野生动物迁移廊道处，即使存在一定程度的人为干扰，其穿越行为也必然发生。根据研究结果，建议今后在野生动物高频穿越通道处加强对人为干扰的控制，为野生动物利用通道营造安全的空间。

To evaluate the effectiveness of wildlife passages on G7 Beijing-Urumqi Expressway (from Balikun to Wutongdaquan section), 17 infrared cameras were used to continuously monitor 12 wildlife passages from March 12, 2023 to June 11, 2025. The results showed that all wildlife passages were used by wild animals, with an utilization rate of 100%, meaning all passages were used by wildlife at least once. Six species of mammals were monitored, of which five were national key protected wild animals. The relative abundance index (RAI) of goitered gazelle (Gazella subgutturosa) and fox (including red fox (Vulpes vulpes) and corsac fox (Vulpes corsac)) was the highest, with 101.50 and 36.07 individually. The RAI of goitered gazelle was the highest in spring and autumn, and that of the fox was higher in spring, autumn and winter. The goitered gazelles are mainly active during the day, while the foxes are mainly active at night. The increase in traffic volume could not significantly limit the use of the passages by the two animals. The overpass and underpass set up at this section are equally important for the crossing of mammals. Currently, no preference for various wild animals has been found. The correlation between the utilization of passages by wild animals and the passage size or habitat factors is not obvious. However, it is significantly positively correlated with human interference, indicating that as long as the animal passage is located at the wildlife migration corridor, even if there is a certain degree of human interference, the behavior of the animals passing through the passage will definitely occur. According to the research results, it is suggested to strengthen the control of human interference at the high-frequency crossing passage of wild animals in the future, so as to create a safe space for wild animals to use the passage.
