1997年至1999年间,在韩国智异山国家公园选取生境相似,但片断化和未片断化不同的调查地.设置8条2 km长截线,调查记录了黄鼬(Mustela sibirica)、黄喉貂(青鼬)(Martes flavigula)、狗獾(Meles meles)、豹猫(Felis bengalensis)、野猪(Sus scrofa)、獐(Hydropotes inermis)、狍(Capreolus)、朝鲜兔(Lepus coreanus)和松鼠的数量,并对影响动物数量的相关因子进行回归分析.结果表明,8块样地虽属两大类不同景观且具有相似植被特征,但在片断化和未片断化中,枯折木,胸高直径(dbh)6~10 cm的树及50 cm的巨树密度,树冠盖度及灌木被度均有明显差异.3年内在8块样地共记录到9种兽类在雪被上留下的足迹,其中5种兽的密度在片断化和未片断化生境中差异明显.9种兽的渐近多元回归中,6种兽的密度同景观和植被变量密切相关,但如果不增加当地生境条件,则足迹链丰富度同植被构成的简单相关性表现得很微弱.在片断化和未片断化的不同景观林区,对兽类的分布及其动态还要做进一步详细研究.
1997年至1999年間,在韓國智異山國傢公園選取生境相似,但片斷化和未片斷化不同的調查地.設置8條2 km長截線,調查記錄瞭黃鼬(Mustela sibirica)、黃喉貂(青鼬)(Martes flavigula)、狗獾(Meles meles)、豹貓(Felis bengalensis)、野豬(Sus scrofa)、獐(Hydropotes inermis)、狍(Capreolus)、朝鮮兔(Lepus coreanus)和鬆鼠的數量,併對影響動物數量的相關因子進行迴歸分析.結果錶明,8塊樣地雖屬兩大類不同景觀且具有相似植被特徵,但在片斷化和未片斷化中,枯摺木,胸高直徑(dbh)6~10 cm的樹及50 cm的巨樹密度,樹冠蓋度及灌木被度均有明顯差異.3年內在8塊樣地共記錄到9種獸類在雪被上留下的足跡,其中5種獸的密度在片斷化和未片斷化生境中差異明顯.9種獸的漸近多元迴歸中,6種獸的密度同景觀和植被變量密切相關,但如果不增加噹地生境條件,則足跡鏈豐富度同植被構成的簡單相關性錶現得很微弱.在片斷化和未片斷化的不同景觀林區,對獸類的分佈及其動態還要做進一步詳細研究.

Tracks of 9 species of mammals, Siberian weasels (Mustela sibirica), yellow-throated martens (Martes flavigula), Eurasian badgers (Meles meles), Bengal cats (Felis bengalensis), wild boars (Sus scrofa), water deer (Hydropotes inermis), roe deer (Capreolus capreolus), Korean hares (Lepus coreanus) and red squirrels (Sciurus vulgaris) were recorded on the snow on eight 2 km transects in forests with similar vegetation features, but within fragmented and unfragmented landscapes in Mt. Chirisan National Park, Korea, from 1997 to 1999. All eight study sites have generally similar vegetation characteristics despite lying within a larger matrix of two different landscapes. Nonetheless, there were significantly differences in density of snags, stems 6-10 cm diameter at breast height (dbh), stem > 50 cm dbh, canopy cover, and shrub coverage between fragmented and unfragmented forests. Nine species of mammals were recorded among 8 study sites in this snow tracking during 3 years. Significant differences were formed density between fragmented and unfragmented forests for 5 mammal species; the others were evenly distributed. Of the 9 mammal species analyzed, 6 species exhibited one or more significant correlations with the landscape or vegetation variables in a stepwise multiple regression. Simple correlations between the abundance of snow tracks and the vegetation structure have limited value if not put into a local and regional habitat context. Distributions and dynamics of mammals in landscapes with fragmented and unfragmented forests ought to be examined more closely.
