Abstract

Benthic macroinvertebrates are important ecological and environmental indicators as primary or secondary consumers, and therefore are widely used in the evaluation of aquatic environments. However, there are no comprehensive river ecosystem monitoring surveys that link the major physicochemical water quality items with benthic macroinvertebrates in urban streams. Therefore, this study investigated the distribution characteristics of benthic macroinvertebrates and physicochemical water quality items (17 items) in Yangjaecheon and Yeouicheon from 2019 to 2020. At the same time, by applying Spearman's rank correlation analysis and nonmetric multidimensional scaling (nMDS) analysis in the water quality data and biotic index, we tried to provide basic data for diagnosing the current status of river ecosystems in major urban rivers in Seoul. Based on the study results, a total of 39 species and 3,787 individuals were identified in Yangjaecheon, the water quality(based on BOD, TOC, and TP) of Yangjaecheon was higher than Grade Ib(good), and the BMI using benthic macroinvertebrates appeared as Grade C(normal) at all the sites. In Yeouicheon, a total of 51 species and 4,199 individuals were identified, the water quality(based on BOD, TOC, TP) was higher than Grade Ib(good) similar to Yangjaecheon, and the BMI of both Upstream and Saewon bridge was Grade B(good), while Yeoui bridge was Grade C(normal). Overall, analysis results for the distribution of benthic macroinvertebrates by a nonmetric multidimensional scaling method showed no significant difference between the two streams (p=0.1491). Also, significant environmental variables related to benthic macroinvertebrates distribution were determined as water temperature and DO. On the other hand, the results of the correlation analysis between biotic index and major water quality items confirmed that R1 and BMI could be used for on-site urban river water quality evaluation.

본 연구에서는 2019년~2020년 2년 동안 양재천과 여의천을 대상으로, 이화학적 수질항목(17항목)과 함께 저서동물지수와 우점도지수 및 다양도지수 등의 군집지수와 연계하여 두 하천의 생태건강성을 평가하였다. 또한 저서동물 생물지수의 현장 적용성 평가 및 및 두 하천 간 저서동물 분포특성을 통계적으로 비교하기 위하여 각각 상관분석(correlation analysis)과 비계량적 다차원척도법(nMDS, nonmetric multidimensional scaling)을 활용하였고, 이를 통해 도심하천의 하천생태계 현황을 진단하는 기초자료를 제공하고자 하였다. 조사 결과, 양재천(주암교, 보도교, 대치교)은 총 39종, 3,787개체가 출현하였으며, 양재천 수질(BOD, TOC, TP 기준)은 II등급(약간 좋음) 이상이며, 저서동물을 이용한 BMI는 모든 지점에서 C등급(보통)으로 나타났다. 여의천(상류, 새원교, 여의교)은 총 51종, 4,199개체가 출현하였으며, 여의천 수질(BOD, TOC, TP 기준)은 양재천과 유사하게 II등급(약간 좋음) 이상으로, BMI는 상류 및 새원교 모두 B등급(좋음), 여의교는 C등급(보통)으로 나타나는 등 전반적으로 양재천과 여의천 모두 수질 및 하천 환경상태는 유사한 것으로 확인되었다. 특히 저서동물 분포상태를 비계량적 다차원척도법으로 분석한 결과에서도 두 하천 간의 유의미한 차이를 볼 수 없었으며(p=0.1491), 이때 수온과 DO 환경인자가 두 하천에서의 저서동물 분포와 상관성이 높은 것으로 나타났다. 저서동물 생물지수와 주요 수질항목과의 상관분석 결과, 풍부도지수와 저서동물지수가 현장 수질평가에 활용될 수 있을 것으로 확인되었다.
