| 中文摘要 | 本研究自2012年7月至2015年9月,選擇林業試驗所太麻里研究中心於1998年所建造的原生闊葉樹種混合林內,以自動監測相機對台灣水鹿之族群動態進行為期39個月、連續12次的持續監測。經辨識後篩選出410筆有效照片紀錄,並換算為出現指數OI,以分析鹿群分布的區域性差異,以及族群數量的波動情形。分析結果發現:本造林地內的台灣水鹿,以雄鹿的出現次數較多,約為雌鹿的2.7倍。鹿群的OI值在各監測點及各監測次間的差異甚大,顯示鹿群在本造林地內分布不均勻,且數量呈現明顯的波動。唯整體而言,鹿群出現於本造林地的數目,呈現穩定增加的趨勢。 |
| 英文摘要 | This study was carried out in a hardwood mixed stand established in 1998 at Taimalii Research Center, TFRI. Camera traps were used to monitor the population dynamics of Formosan Sambar (Rusa unicolor swinhoii) during July, 2012 to September, 2015. After 12 series of continuous monitoring for 39 months, 410 valid picture records were identified and compose to the occurrence index (OI) composed for different monitoring points and periods to analyze the distribution and fluctuation of sambar's population. According to the results, the effective records of male sambar was higher than female's with a ratio of (♀:♂=1:2.7). Obvious variation occurred between both monitoring points and times on the OI of sambar's population, showing that the distribution of sambar's population was uneven in the stand and inclined to group at "hot spots". Meanwhile, the relative abundance of sambar's population fluctuated and grew stably during the monitoring period. |
