玉山國家公園楠溪流域上游永久樣區蔓藤生態之調查計畫9

The vine ecological studies in the permanent plot at the upstream region of Nantzuhsien Creek in Yushan National Park
中文摘要
一、緣起及調查過程
楠梓仙溪林道9.5~10k 西面的常綠闊葉林為可及性高,且鮮少人為干擾的大面積天然森林,極適合發展成範圍達10公頃以上森林永久樣區,以建構臺灣闊葉樹林帶更完整的資料。本計畫的目的擬藉由2005年設立之楠溪1公頃森林永久樣區,涵蓋該集水區上坡、下坡及溪谷等該區各類生育地,進一步建立蔓藤調查研究。計畫內容包括建立蔓藤調查標準程序、執行樣區內蔓藤植物種類與分布的調查分析、蒐集蔓藤的影像和基本資料,並編寫調查手冊,以供生態教育宣導解說之用。延續10公頃永久樣區的發展,提供國家公園經營管理和長期生態研究的基礎資料。
二、重要結果
本研究今年度完成1公頃H樣區蔓藤調查及檢測的工作,共記錄22科29屬38種,其中被調查記錄的蔓藤有118科21屬27種1494株1667枝,可供做每木調查長期監測研究的樣株,依重要值結果:胡椒科植物的風藤為19.097%、桑科的珍珠蓮(7.878%)和愛玉子(7.923%)、五加科的三葉五加為9.217%、紫金牛科的賽山椒為9.538%與衛矛科光果南蛇藤的8.71%,合計62.343%,為最常見的科別和種類;以攀附型風藤的數量特多,而懸立型的光果南蛇藤胸高斷面積總合最高,為樣區中較優勢的種類。調查期間利用觀察到的蔓藤種類,編寫蔓藤調查辨識概要、類近蔓藤植物之區分、蔓藤植物的檢索及重要蔓藤植物的簡介。
雙向列表分析結果將H樣區區分為4個蔓藤植物社會型,緩上坡林隙區懸立型蔓藤植物社會型、近溪谷破空區懸立型蔓藤植物社會型、陡坡林下區攀爬型蔓藤植物社會型和緩下坡林緣疏隙區攀附型蔓藤植物社會型。廣泛分布型蔓藤如:風藤、賽山椒等,較特別的是以光果南蛇藤、三葉五加、南五味子為代表型的近溪谷破空區蔓藤植物社會;另以大枝掛繡球、珍珠蓮和愛玉子等為攀附蔓藤代表的緩下坡林緣疏隙區和陡坡林下區植物社會;其他如大葉南蛇藤主要在緩上坡林隙區,但以零散分布方式的藤花椒或飛龍掌血,也是此樣區代表性的蔓藤特性。蔓藤植物社會的物種或樣區並沒有明顯的界線,然而是否與攀爬機制相關,抑或是與林隙或崩塌地形相關,則需長期監測和比較,並深入廣泛蒐集更多環境資訊。
本研究也附加記錄臺灣五葉參為特有且稀有的附生性蔓性灌木,列在名錄中供參考,並統計其木質根徑大於1cm者有10根,合計胸高斷面積為0.0085 m2/ha,比對蔓藤莖統合計算其重要值可達0.007%,位最後1名。
三、主要建議事項
永久樣區森林動態研究是保育的基礎,目前林務局已規劃針對大型核心樣區永續提供經費做定期的複查,楠溪樣區也納入核心樣區範圍,但除了劃設樣區及長期監測喬木和灌木,玉山國家公園可以經營建構多面向的調查,增添永久樣區的保育基礎資料,也顯現國家公園有別於其他單位對保育生態的貢獻特色。其中蔓藤植物生態之調查是值得持續支持的延續擴展計畫,樣區物候及小苗基礎資料建立也是應陸續完成,不僅可提供生態調查及保育解說相關資訊,也因此達成臺灣第一個中海拔大型永久樣區的長期監測任務。
英文摘要
The evergreen broad-leaved forest west to about 9.5~10k of forest road is reachable and also little human interference. This natural forest is very suitable for developing an area of more than 10 hectares permanent plot in order to establish integrated information about the broad-leaved forest in Taiwan. The purpose of this project is to follow up the set-up long-term monitoring plot where covering habitats of the uphill, downhill and creek areas and to fulfill further investigation of vines. This project includes the establishment of standard procedures for vines’ inventory protocol, the inventory of vines, the analysis of vines’ distribution, and the collection of vines’ images and data to prepare a manual for vines’ inventory. It can provide a niche for the ecological education and demonstration. Carrying on the development of 10-hectare permanent plot can bear monitoring data and renewal information for National Parks management and long-term ecological research. This study completed the inventory and recorded a total of 38 species of 29 genera in 22 families. Among them, only 1667 stems from 1494 vines and 27 species of 21 genera in 18 families were used for survey and long-term monitoring. It resulted in the IV (=important value) was 19.097% of Piper kadsura (Choisy) Ohwi (Piperaceae), 7.878% of Ficus sarmentosa Buch.-Ham. ex J. E. Sm. var. nipponica, 7.923% of Ficus pumila L. var. awkeotsang (Makino) Corner (Moraceae), 9.217% of Eleutherococcus trifoliatus (L.) S. Y. Hu (Araliaceae), 9.538% of Embelia lenticellata Hayata (Myrsinaceae) and 8.71% of Celastrus punctatus Thunb (Celastraceae); as a total of 62.343%. Those were the common families and species in H plot. The attaching P. kadsura were with the great number. The suspending C. punctatus had the largest basal area. Both were the dominant species in H plot. During investigation, a protocol for identification and inventory of vines, the classification of similar vines, a key for vines in the studied plot and the introduction of certain important vines were fulfilled. TWINSPAN (= two-way indicator species analysis) results in 4 patterns of vine communities; i. e. Suspending vine community around the forest gap at upper slope, Suspending vine community near the creek valley with large gaps, Attaching vine community at steep slope or beneath the tree crown and Attaching vine community at forest edge with small interruption of tree crown usually at lower slope. The extensive distribution as P. kadsura and E. lenticellata are among 4 patterns. The representatives of suspending vine community near the creek valley with large gaps are C. punctatus, E. trifoliatus and Kadsura japonica (L.) Dunal. On the other hand, Hydrangea integrifolia Hayata ex Matsum. & Hayata, F. sarmentosa var. nipponica.and F. pumila var. Awkeotsang represents the association of areas at steep slope or beneath the tree crown and at forest edge with small interruption of tree crown usually at lower slope. The C. kusanoi Hayata is the identity for suspending vine community around the forest gap at upper slope. Most of the rest, such as Zanthoxylum scandens Blume and Toddalia asiatica (L.) Lam., are sparsely distributed. The boundary among the species or among the plots is not very obvious. Whether it is related to climbing mechanism, gaps or topography needs long-term monitoring and further investigation. This study includes the record of rare endemic Pentapanax castanopsisicola Hayata which is epiphytic suspending shrubs. The list and analysis of its woody roots over 1cm diameter are 10 with the basal area of 0.0085 m2/ha and the IV of 0.007%. It is the least important on the list. These results can provide for dynamic study, conservation, education and other related studies in the future. The sustaining for projects in the ecology of vines becomes fruitful, meaningful and important. It would also carry on the important mission of long-term monitoring at the first large permanent plot at middle altitude of Taiwan.
