초록
본 연구에서는 TOPSIS(Techniques for Order Performance by Similarity to Ieal Solution)을 이용하여 낙동강수계 34개지천에서의 수질측정망 설치 지점에 대하여 평가하였다. 낙동강수계에서는 지난 2011년부터 195개 지천에서 수질 및 유량을측정하고 있다. 특히, 34개 중점관리지점은 오염원이 많고 수질이 불량한 지역으로서 지속적인 수질이 관리가 필요하다. 관리가필요한 지점 선정을 위해 평가항목은 10개 지표를 선정하였으며 선정된 지표를 표준화하고, 엔트로피 방법(Entropy Method) 을 이용하여 가중치를 부여하였다. 가중치 산정결과, 인근 측정망 유무가 가장 크고 평균 수질과 산업단지 유무도 높은 가중치를얻었다. 평가결과, 상위 지점은 인근 측정망이 없고 산업단지와 폐수처리시설이 있고 평균 수질이 타 지점보다 높은 지점이다. 평가된 자료는 향후 낙동강수계에서의 신규 수질측정망 설정 및 지속적인 지류에서의 수질 관리를 위해 필요한 연구 결과로판단된다.
Abstract
In this study, TOPSIS(Techniques for Order Performance by Similarity to Ieal Solution) was used to evaluate the installation points of water quality monitoring networks in 34 streams of the Nakdong River watershed. The Nakdong River System has been measuring water quality and flow in 195 local streams since 2011. In particular, the 34 key management points are areas with many pollutants and poor water quality, requiring continuous water quality management. For the selection of points requiring management, 10 indicators were selected for evaluation, and the selected indicators were standardized and weighted using the entropy method. As a result of weight calculation, the presence or absence of a nearby measuring network received the greatest weight, and the average water quality and presence of an industrial complex obtained the highest weight. The evaluated data are judged to be the research results necessary for the establishment of a new water quality measurement network in the Nakdong River system and continuous water quality management in tributaries.
