Abstract

The purpose of this study is to propose the rational mountain stream management strategy considering the natural conditions and social needs of the Republic of Korea. We reviewed domestic and overseas studies related to mountain streams, identified the study areas by text mining and co-word analysis using the VOSviewer program, and then analyzed the spatial and temporal study trends and topics of each study area. The results showed that domestic studies on mountain streams are still in an initial stage compared to overseas studies. Overseas studies on mountain streams can be classified into four groups: (i) habitat and species composition of fish and invertebrates, (ii) hydrological phenomena and nutrient migration, (iii) transport of sediment and organic materials and the relevant morphological changes by runoff flows, and (iv) plant species composition in mountain streams. Of these study subjects, domestic studies belonging to the (i) group mainly focused on macroinvertebrates while domestic studies belonging to the (iii) group regarded transport of sediment and organic materials as not the ecological disturbance but the source of sediment-related disasters. We then analyzed the rate of each research group to all papers by period and country. The results showed that the overseas studies belonging to (iii) and (iv) groups have increased with time, and the increase was mostly due to the studies in the United States, Brazil, Canada, and China. On the other hand, domestic studies belonging to (i) and (iii) groups increased somewhat with time, but there was a slight lack of correlation between the two subjects. Therefore, the hybridity studies to complement the shortage is necessary for the future.

이 연구에서는 우리나라의 자연환경 조건 및 사회적 요구를 반영한 산지하천의 합리적 관리방안을 제시하기 위한 연구의 일환으로 산지하천을 대상으로 한 국제 국내 연구논문을 수집 및 분석한 후, VOSviewer 프로그램을 이용한 텍스트마이닝과 동시출현단어 분석을 통하여 연구주제에 따른 연구영역을 구별하였으며, 이후 각 연구영역별로 시 공간적인 연구동향을 비교하였다. 그 결과, 산지하천을 대상으로 한 국내 연구논문은 국제 연구논문에 비하여 초보적인 단계에 있음을 확인할 수 있었다. 즉, 국제 연구논문은 산지하천의 어류 및 무척추동물의 서식환경과 종구성에 관한 연구영역(제1연구영역), 산지하천에서의 수문현상 및 양분이동에 관한 연구영역(제2연구영역), 산지하천에서의 유수에 의한 하상물질 이동 및 지형 변화에 관한 연구영역(제3연구영역), 산지하천 주변의 식물종 구성에 관한 연구영역(제4연구영역)으로 구분되었다. 이 중 제1연구영역과 관련된 국내 연구논문은 주로 대형무척추동물만을 연구소재로 하고 있었으며, 제3연구영역과 관련된 국내 연구논문은 유수에 의한 하상물질 이동 및 지형 변화를 생태계의 교란작용이 아닌 산지토사재해의 원인으로 간주하고 있다는 것을 알 수 있었다. 이렇게 구분된 각 연구영역이 전체 연구논문 중에서 점유하고 있는 비율을 시기별 국가별로 파악한 결과, 국제 연구논문의 경우 3 4연구영역에 해당하는 연구논문이 증가하는 것으로 나타났으며, 여기에는 미국을 중심으로 브라질 캐나다 중국의 영향이 크게 작용하였다. 이와 달리 국내 연구논문의 경우 1 3연구영역에 해당하는 연구논문이 시간의 경과에 따라 다소 증가하였으나, 이 두 연구영역 간 상호 연관성은 다소 부족한 것으로 나타났다. 따라서 향후에는 이를 보완한 하이브리드 성격의 연구가 필요할 것으로 사료된다.
