中文摘要 | 本研究2001年於合歡山區8個池沼進行水質與底棲大型無脊椎動物調查,共紀錄底棲大型無脊椎動物3綱7目8科17種 (taxa) 32,686隻。包括雙翅目9種,毛翅目3種,貧毛綱、雙殼綱、蜉蝣目、蜻蛉目、鞘翅目各1種。就數量比較,雙翅目佔總隻數的93.3%,為最主要分類群。另外以典型對應分析法 (CCA) 探討水質因子與物種分布的關係,結果CCA前2軸共解釋生物資料46.7%變異。由樣區在CCA前2軸的排序分布顯示,8個池沼可歸類為3群。St. 7合歡碧池為貧腐水型池沼,主要對應水質要求高的非耐污種類。St. 8天巒池屬中腐水型池沼,主要對應中度耐污種類。Sts. 1~6為富腐水型池沼,主要對應耐污種類。 |
英文摘要 | This study was conducted to survey water quality and benthic macroinvertebrates at eight ponds in the Mt. Hohuan area in 2001. In total, 32,686 specimens of benthic macroinvertebrates belonging to three classes, seven orders, eight families, and 17 taxa were collected. These taxa included nine taxa of Diptera, three taxa of Tricoptera, and one taxon for each group of the Oligochaeta, Bivalvia, Ephemeroptera, Odonata, and Coleoptera. Diptera were the most abundant taxa, and they accounted for 93.3% of individuals. The relationships between water quality and benthic macroinvertebrates were assessed by canonical correspondence analysis (CCA). The first two CCA axes explained about 46.7% of the variance in the macroinvertebrate assemblages. Based on the ordination on the first two CCA axes, the plots were divided into three groups. Benthic macroinvertebrates at site 7 corresponded to intolerant taxa, and site 7 was classified into an oligosaprobic pond typology. Sites 1-6 had benthic macroinvertebrates belonging to tolerant taxa, and were classified as a polysaprobic pond typology. Site 8 contained taxa that had medium tolerance to poor water quality, and was determined to have a mesosaprobic pond typology. |
