Abstract

In recent years, the frequency and magnitude of landslide disasters have increased due to the rise in extreme rainfall associated with climate change. Consequently, there is a growing need for a systematic understanding of research trends in landslide studies. This study aimed to identify trends in international and domestic landslide research by analyzing research papers published between 2006 and 2022 using co-occurrence word analysis. The results show that international landslide research has steadily increased in volume since 2006, whereas domestic research has shown a declining trend since 2016. In terms of research output by country, South Korea ranked 15th among 166 countries in terms of number of studies published. The co-occurrence word analysis revealed that international research papers can be categorized into four research areas with strong interconnections among them. In contrast, domestic research papers were classified into three research areas with relatively weak interconnections. These findings suggest that future landslide research in Korea should strengthen interdisciplinary collaboration across various research fields and focus on landslide prediction and prevention in response to ongoing climate change.

기후변화로 인한 극한 호우 증가로 산사태로 인한 산지재해의 발생 빈도와 규모가 증가하고 있다. 이에 따라 산사태 연구의 체계적인 동향 파악의 필요성이 커지고 있다. 이 연구는 2006년부터 2022년까지 발표된 국제 및 국내 산사태 관련 연구논문을 수집하고 동시출현단어 분석을 통해 산사태 연구동향을 파악하고자 수행하였다. 분석 결과 국제 산사태 연구는 지속적으로 증가하는 추세를 보인 반면 국내 연구는 2016년 이후 감소하는 경향을 나타냈다. 국가별 연구동향에서는 대한민국이 166개국 중 상위 15위 수준으로 나타났다. 동시출현단어 분석 결과 국제 연구논문은 4개의 연구영역으로 구분되었으며, 연구영역 간 상호연관성이 확인되었다. 반면 국내 연구논문은 3개의 연구영역으로 구분되었으나 연구영역 간 연계성이 상대적으로 낮은 것으로 나타났다. 이러한 결과는 향후 국내 산사태 연구에서 다양한 연구분야 간의 상호연계를 강화하고 기후변화에 대응한 산사태 예측 및 예방 연구의 확대가 필요함을 시사한다.
