초록

This study aims to figure out the community patterns of benthic macroinvertebrates and analyze the relations between the communities and water quality in the Pungyeongjeong Stream. We collected the samples four times by season. The number of species was 28 and dominant species were Cheumatopsyche brevilineata, Hydropsyche kozhantschikovi, Baetis fuscatus, Chironomidae spp. and so on. The range of dominant index was 0.54 to 0.93 and mean of it was 0.77. The range of diversity index was 0.94 to 2.54 and mean of it was 1.75. Ratios of filtering-collectors and clingers got lower but gathering-collectors and sprawlers got higher from upper stream to lower stream. The results of Pearson correlation analysis showed COD, SS, TOC and total coliforms were highly related with biotic indices of benthic macroinvertebrates. The results of cluster analysis and non-metric multidimensional scaling ordination showed that the survey sites and periods were divided into three groups. The survey sites were divided into upper stream and middle-lower stream. The survey period were divided into winter season and other seasons. Distribution of benthic macroinvertebrates was showed some characteristics according to various influence factors, however long-term and regular investigations were thought to need for analysis and prediction with various statistical methods.
