交通噪声干扰下的黄腹角雉适生区识别与分区优化——以武夷山国家公园为例

Identification and zoning optimization of the habitat areas for the Tragopan caboti under traffic noise interference: A case study of Wuyishan National Park

  • 摘要: 交通噪声会掩盖野生动物的声音讯号并对其适生区分布造成严重影响。探讨交通噪声干扰下的野生动物适生区分布的准确识别方法,对国家公园生态分区精细化管理具有重要意义。以武夷山国家公园东部景区以及国家Ⅰ级保护动物黄腹角雉为例,通过采集腹角雉鸣叫声以及交通噪声数据,对比分析两者的声音频谱,并借助SoundPLAN, ArcGIS软件模拟交通噪声分布和黄腹角雉潜在适生区并进行叠加分析,得出结果如下:(1)交通噪声在频率分布上对黄腹角雉叫声覆盖率高达99.96%,且在黄腹角雉的敏感听域3 100~4 995.70 Hz范围内形成完全掩蔽;(2)黄腹角雉潜在适生区受交通噪声干扰形成了“噪声胁迫区-适生区”的分布格局,交通噪声使黄腹角雉丧失了近45.65%的适生区域并进一步导致其适生区破碎化。在此基础上,文中的研究为受交通噪声影响的黄腹角雉潜在适生区制定差异化分区优化策略提供参考依据。

     

    Abstract: Traffic noise may mask the acoustic signals of wild animals and have a significant impact on their habitat distribution. It is crucial to accurately identify wildlife habitat distribution under traffic noise interference for effective management of national park ecological zones. Taking the eastern scenic area of Wuyi Mountain National Park and Tragopan caboti, a national class Ⅰ protected animal as an example, this study collect Tragopan caboti calls and traffic noise data. By comparing and analyzing the acoustic spectra of these two sounds, and using SoundPLAN and ArcGIS to simulate traffic noise distribution and potential habitat areas for Tragopan caboti, the following results are obtained: Traffic noise covered 99.96% of the frequency range of Tragopan caboti calls, forming complete masking within their sensitive hearing threshold (3100-4995.70 Hz). Additionally, potential habitat areas for Tragopan caboti are disturbed by traffic noise interference, resulting in a"Noise stress zone-Habitat zone", distribution pattern that caused a loss of nearly 45.65% in its habitat areas while further fragmenting them. Based on these findings, this study provides insights into developing differentiated zoning optimization strategies for potential habitat areas affected by traffic noise.
