为更好地保护和管理部分哺乳类动物及其栖息地 ,自 2 0 0 1年 6月至 2 0 0 2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。

Characteristics of vegetation structure in breeding area of Siberian rubythroat (Luscinia calliope) in Daecheongbong peak, Mt. Seoraksan national park, South Korea

Most of forest birds have the characteristics for habitat selection. The purpose of this study is to clarify the vegetation structure in breeding area of Siberian rubythroat (Luscinia calliope). In Daecheongbong peak, Mt. Seoraksan national park, South Korea from May to August, 2001, breeding population of Siberian rubythroat and the dominant species in breeding area of Siberian rubythroat (Luscinia calliope) were surveyed by line transect method along the ridge in the Daecheongbong peak area. Number of individuals and location of song posts were observed and recorded. According to the survey results, the study area was classified into high, middle and low density areas. Those birds selected the forest area of dominant species for Ermans birch and dwarf Siberian pine as habitat and preferred the shrubs area with the lower height and higher coverage.

Influence of roads on small rodents population in fragmented forest areas, South Korea

引用

Journal of Forestry Research 2003年第2期14卷 155-158页

作者：任信在李昌培许位行朴容秀崔瑞允朴仁珠李宇新汉城大学校演习林汉城大学校山林资源学科黑龙江省林业科学院

The road effect on small rodent population is investigated at 8 fragmented forest areas in the Baekdudaegan mountain range, South Korea in September 2001. We especially focused on the distribution and body condition of small rodents near the roads. Korean field mouse (Apodemus peninsulae) seems to be more sensitive to the existence of a road than striped field mouse (Apodemus agrarius). Korean field mouse prefers interior forest area to around road. Striped field mouse is a habitat generalist and has wide distributional range around road, but Korean field mouse is forest-inhabiting species and their distribution is limited in forest area. These results suggest the effect of road is different on each small rodent species and their habitat preferences.
