道路两边不同距离内哺乳动物丰富度的差异

为更好地保护和管理部分哺乳类动物及其栖息地，自2001年6月至2002年3月在韩国白头大干山脉8个被道路切割的林区内调查了道路两边一定距离内所见哺乳动物随距离增加而变化的丰富度。我们共调查了10种哺乳类(野猪、狍、獐、黄鼬、貉、豹猫、华南兔、松鼠、花鼠、鼹)的各种痕迹(粪便、足迹、食痕、卧迹及休息处)，发现距道路近处两边的丰富度确有较大下降。这说明道路建设的确影响哺乳类的生境选择及其利用方式。所以今后在道路设计、管理及扩充等方面均需充分考虑和满足所有野生动物整个生命过程所需的空间要求。

Differences in Mammal's Abundance in Different Distance Areas from Road

This study was conducted from June 2001 to March 2002 to obtain the basic information in mammal′s abundance caused by the road construction in different distance areas for sound protection and management of mammal′s and their habitats in 8 fragmented forest areas of Baekdudaegan mountain range. Field signs such as feces, foot print, feeding, roosting, and resting site of 10 mammal species could be found. Mammals abundances were much lower near roads. This means that roads would affect habitat usage patterns of mammals. Road design, management, and restoration need to be more carefully tailored to address full requirement of ecological processes for wildlife species that may be affected.
