摘要

本研究配合臺東林區管理處「國家步道系統建置與發展計畫」，自2006年8月至2007年4月，進行臺東海岸山脈南段植物資源調查。在41條樣帶中，維管束植物計有l38科485屬758種，其中40種隸屬稀有瀕危物種。700m左右的森林中具有較高的物種數出現。植物社會由低海拔至高海拔分別爲：構樹－血桐植群型、通脫木植群型及菱葉衛矛植群型。臺東海岸山脈南段國家步道計有：堺橋溪步道、麻荖漏步道、都蘭山步道及石膏山步道，其中堺橋溪步道及都蘭山步道涵蓋通脫木植群型及菱葉衛矛植群型，麻著漏步道及石膏山步道均屬通脫木植群型。四條步道各具其特色：堺橋溪步道中途有一百年榕樹的特殊景觀，麻荖漏步道藤本植物及著生性植物繁多；都蘭山步道植物種類最爲豐富；石膏山步道植物以陽性先驅物種佔優勢。爲增進這些步道的使用，植物資源應繼續監測並加以保護之。

This study was executed from August, 2006 to April, 2007 in accordance with the establishment and development of national trail system of Taitung Forest District office. Plant resources were investigated in south part of east coastal mountain range. The results revealed that vascular plant species comprises 758 species and 485 genus in 138 families which possessed 40 endangered species within total 41 sampled transects. Abundant plant species appeared in elevation of 700 m. Plant community showed Broussonetia papyrifera-Macaranga tanarius association, Tetrapanax papyrferus association and Euonymus tashiroi association with the increasing elevation, respectively. National trails of south part of costal mountain range mainly consisted of Je-Chiao-Shi trail, Ma-Lau-Lou trail Du-Lan-Shan trail and Shih-Kao-Shan trail. Of that, Je-Chiao-Shi trail and Du-Lan-Shan trail comprised Tetrapanax papyriferus and Euonymus tashiroi associations. The vegetation association of Ma-Lau-Lou trail and Shih-Kao-Shan trails belonged to Tetrapanax papyriferus association. Four trails had their own unique features, which were special landscape of a-hundred-year Ficus in Je-Chiao-Shi trail, prosperous lianas and attaching plants in Ma-Lau-Lou trail, the most abundant plant species in Du-Lan-Shan trail and dominant pioneer species in Shih-Kao-Shan trail. For promoting the use of these trails, plant resources should be continually monitored and maintained in this area.
