中文摘要 | 本研究在瞭解台北植物園之蝶相,並嘗試探討園中植物變化和經營管理方式對蝶相及其族群的影響。1989及1999年每月以穿越線調查法在台北植物園調查蝶類之種類和數量。1989年紀錄了7科47種1411隻次的蝶類,1999年紀錄了7科60種2221隻次,另檢查及鑑定1945年至1988年林業試驗所昆蟲標本館中採自植物園之蝶類標本共7科41種。台北植物園自1996年起其經營管理有很大變化,增設了許多主題展示區,增加的植物種類近600種,其中不少是蝶類的食草或蜜源植物,增加了蝶類族群數量和多樣性。但對蝶類造成負面影響的有除草的次數及竹區的改變,造成取食禾本科及竹類植物的單帶挵蝶類和玉帶蔭蝶的數量驟降。由本研究的結果可以看出園區植物的改變與蝴蝶的種類和族群數量關係密切,並可作為棲地經營管理與物種保育的參考。 |
英文摘要 | This study focuses on the butterfly fauna and population changes at in Taipei Botanical Garden, and attempts to determine the influence of changes in plants and management practices. The butterfly fauna of Taipei Botanical Garden was investigated by transect count monthly in 1989 and 1999. There were 47 species (1411 individual counts) recorded in 1989 and 60 species (2221 individual counts) in 1999; there were 41 species in 7 families recorded from 1945 to 1988 in the collection of the Insect Museum. The management of Taipei Botanical Garden was modified in 1996. Many new exhibition sections were created in and 600 new plants were transplanted into the investigated areas. Many of them are host plants or nectar plants of butterflies, thus contributing to the increase in the butterfly population and species diversity. However, digging in the bamboo section and the increased frequency of weeding have caused significant decreases in Parnara spp. and Lethe europa pavida (Fru.), which respectively feed on the Poaceae and bamboo. The results of this study can serve as a reference for habitat management and species conservation. |
