復育物種選擇之研究 - 以蓮華池地區為例

Abstract

復育生態學在世界上已經成為生態學上重要的學科之一，但台灣在植群復育作業的物種選擇上缺乏客觀的操作標準，於是本研究選擇了台灣中部低海拔保存最完整的天然闊葉林及受到開發為人工林、果園等人為干擾的蓮華池地區作為研究目標，嘗試以蓮華池地區的物種分布型態為案例提出在此地進行植相復育時物種與植群型的建議。本研究透過蓮華池樣區與植群樣區的代表性研究得出在復育地為中心半徑15km內設置30個樣區可初步建構該地的代表性植群，並將樣區資料進行分群，蓮華池動態樣區經過分群可分為2型9亞型；植群樣區則可分為2型7亞型。利用多樣性指數及多樣性貢獻度找出地區中屬於普通狀態的樣區及特殊狀態的樣區，再透過擬合物種豐度模型將樣區演替程度進行分類，依照復育目標找出樣區內較理想的植群型態，最後配合植群型及其物種進行復育規劃。

Restoration ecology has been an important science in the world, but there was not an objective rule to chose species in restoration procedure in Taiwan. This object chose the most protected natural forest at low altitude in Lienhuachih lake reigion which has artificial forest, orchard and landslide part as our research target. Trying to build a guide of species choosing when planning a restoration project. According to the representive research, we find that taking 30 plots arround the restoration place in 15km radius can construct the typical vegetation type.And make the Lienhuachih forest dynamics plots into 2 association and 9 subassociation, also the vegetation map plots into 2 association and 7 subassociation. Than we use diversity ordering and diversity contribution of samples to find the normal type stand and unique type stand in our plots. We use species abundance model to reclass plots into different succession stages, finding the most valueable sample to be the examplar. After all we use these information to give suggestion to the procedure of rebuilding a ecosystem.
