碩士 / 大仁科技大學 / 環境管理研究所 / 97 / The purpose of this study is to investigate the correlation of environmental variables and the distribution of macro-invertebrate in Hualien River Basin. The multivariate statistical analyses, canonical community ordination analysis (CANOCO), are used to analyze the relationship between environmental factors and macro-invertebrate distribution. According to the results of multivariate statistical analysis, the impact causing by major environmental factors on macro-invertebrate distribution will be demonstrated in the study.
The results shown that gathering collector species are the dominant species among the 61 species collected from Hualien River Basin. The samples can be divided into three groups based on the results from the CANOCO analysis, the one group are the variation of altitude which reveal clearly different variations. Another group are the Genus Baetis (Oder: Ephemeroptera, Family: Baetidae) which live in thick vegetation among sampling station. The other group is the species which live in the contaminated river environment. In all, the altitude and vegetation are the major factors to affect the distribution of macro-invertebrate in Hualien River Basin.
