동시출현단어 분석을 통한 산사태 연구 동향

초록

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.
