摘要

本研究自民國76年11月至77年10月，在太魯閣國家公園東部境內進行。初步結果共計發現92種鳥類。在56種陸棲為主之鳥類與棲地之關係上，吾人利用因素分析方法，以三個新因素來代替原來九個棲地因子，此三個因素共可解釋59.3%的原棲地因子的變異。第一因素和森林下層及灌芒地呈較大正相關。第二因素和森林中、上層呈較大正相關，而此二因素皆與耕地呈較大負相關。第三因素則和開墾區的低草地呈較大正相關。由鳥類在此三因素軸所形成的空間的位置，可以看其利用棲地之情形。

Study were conducted at eastern Taroko National Park during Nov. 1987 and Oct. 1988. A total of 92 species were recorded, of which 56 species of landbirds and their habitat relationships were described using factor analysis method.Results showed that 3 new factors that was capable of explaining 59.3% of variation of original 9 habitat variables were derived. The first factor were highly positively correlated with variables, understory and grassland, while the second were highly positively correlated with variable, overstory. However both factors are highly negatively correlated with variable, plantation. The third were highly positively correlated with variable, low-grassland. With facor score on each 3 factor axes, each bird species has its location in the ordination space.
