摘要
为评估阿尔泰山区旅游公路对典型食草动物马鹿迁移的阻隔影响程度,选择铁热克提—贾登峪旅游公路(简称“铁贾路”)沿线为研究区域,基于地形、植被、水源和人类干扰因子,构建生境适宜性评价准则,利用LinkageMapper工具模拟马鹿迁移廊道,评估铁贾路对马鹿迁移的阻隔影响。结果显示,马鹿适宜生境占路域两侧各1.6km缓冲区的41%~43%,集中于海拔1600~2000m的山地疏林草原带;铁贾路穿越马鹿3处核心生境(K3+860—K10+240、K13+840—K16+180、K16+520—K22+840),与5处生态夹点和2处高价值廊道(K2+640、K13+420)相交,影响路段长度占研究路段总长的68.4%;2024—2025年红外相机监测结果验证了核心生境和廊道模拟的准确性。建议在K2+640、K13+420等高价值廊道和夹点处设置警示标志和采取交通管控等措施,以减轻阻隔效应,维持交通运营安全。研究结果为阿尔泰山区马鹿保护和公路安全运营提供了科学依据,可为阿尔泰山跨境保护地大型哺乳动物保护与基础设施建设协调发展提供参考。
To evaluate the extent to which tourism highways in the Altai Mountains obstruct the migration of typical herbivorous animals(red deer),the area along the Tielieketi-Jadengyu tourism highway(referred to as"Tie-Jia Road")was selected as the study region.Based on factors such as topography,vegetation,water sources,and human disturbance,a habitat suitability evaluation criterion was established.Combined with the Linkage Mapper tool,red deer migration corridors were simulated to assess the obstruction impact of the Tie-Jia Road on its migration.The results indicate that suitable red deer habitats account for 41%~43%of the 1.6 km buffer zone on both sides of the road,primarily concentrated in the montane open forest-grassland belt at altitudes of 1600~2000 m.The Tie-Jia Road crosses three core habitats(K3+860—K10+240,K13+840—K16+180,K16+520—K22+840),intersecting five ecological pinch points and two high-value corridors(K2+640,K13+420),with the affected section comprising 68.4%of the total study road length.Infrared camera monitoring from 2024 to 2025 validated the accuracy of the simulated core habitats and corridors.It is recommended to install warning signs and implement traffic control measures at high-value corridors and pinch points such as K2+640 and K13+420,to mitigate obstruction effects and maintain traffic safety.This study provides a scientific basis for red deer conservation and highway operation safety in the Altai Mountains,offering reference for the coordinated development of large mammal conservation and infrastructure construction in transboundary protected areas of the Altai Mountains.
