| 摘 要： | 以西藏“一江两河”国家一级保护动物黑颈鹤为研究对象。通过铁路噪声源强模拟，研究铁路噪声对野生动物影响机制。研究结果表明黑颈鹤在环境噪声提高时，首先会因警惕行为而驻足倾听，而后随环境噪声增至60dB时出现避让奔逃的现象，至距离噪声源60m以上时停止奔逃，但群体仍处于躁动状态直至平静。采用铁路噪声源强模拟的方法，对于完善铁路工程的环境影响评价工作，尤其是对于建立科学的野生动物影响评价技术与保护措施具有重要的指导意义与现实意义。

| Abstract: | In Tibet,this paper studied the impact of railway noise on Grus nigricollis,the first class national protected animals.By the simulation of railway noise source,the research also studied the impact mechanism of it on wildlife.This research showed that with the increase of environmental noise,first,the wildlife will stop and listen because of alert behavior;second,it will run away with the environmental noise up to 60dB;third,it will run to a distance of more than 60m away from the noise source,and the group... |
