摘要: 

台灣梅花鹿因於1969年在野外絕跡,因此墾丁國家公園管理處於1984年進行台灣梅花鹿復育工作,自1994至1997年陸續野放後,鹿群已逐漸擴大至社頂周邊地區。目前野放鹿群已擴大至4000公頃的廣大範圍,因此將針對目前台灣梅花鹿較大的活動範圍,做穿越線調查。調查結果休息處所在乾、濕季節中,乾季5個月中有47處,濕季6個月中有44處。濕季較少,可能由於被雨水沖刷,不易找到痕跡。地形方面,鹿選擇休息處所偏好在稜線上,因視野較廣且易逃避天敵。坡度方面,平坦地比例較高,可能躺在平坦地較舒服。地表狀況方面,在草地和裸土各半的比例較高。灌叢密度方面,稀少處比例較高。植被方面,較偏好半落葉混淆林,較不會利用草原。遮蔽度方面,偏愛遮蔽度較高的地方。樹大小方面,較偏好有隱蔽的中等樹木林地。風速方面,喜愛在風速較強處。以上顯示鹿隻對休息處所會有所選擇,這些生態因子和逃避天敵及溫度調節有關。

外文摘要: 

Because of population extinction of wild formosan Sike deer (Cervus nippon taiouanus) in 1969, Kenting National Park launched a Sika deer restoration program in 1984. In the year from 1994 to 1997, Sike deer was released to the field. Currently, homerange of the deer has expanded to 4000 hectares. So, we put eyes on the sphere of activities about Formosan Sika deer and investigate into line transect survey. Therefore, we carried out the research in dry and wet seasons, finding 47 sites in five months of dry seasons and 44 sites in six months of wet seasons. The rain scouring may be the reason causing less number in wet seasons. For terrain, Sika deer prefer to choose crest line as their bedding sites, where provide broad eyesight and escape natural enemy easily. For gradient, the resting places in flat-place occupied higher rate, where is more comfortable for Sika deer. Furthermore, the condition of surface for Sika deer, the bedding sites of lawn and bare earth accounted for 50% respectively have higher rate. For the density of boscage, the sparse places has higher rate. Moreover, the vegetation for sida deer, preferring to choose deciduous forest not grasslands. In addition, they prefer to secret places where covered thicket as their shelter. Besides Sika deer prefer to high wind speed place. All of above show that Sika deer have about their bedding sites which has relationship with escaping natural enemies and the temperature control.
