Abstract

The purpose of this study was to analyze domestic research trends over the past 20 years and future direction of forest ecology using text mining. A total of 1,015 academic papers and keywords data related to forest ecology were collected by the "Research and Information Service Section" and analyzed using big data analysis programs, such as Textom and UCINET. From the results of word frequency and N-gram analyses, we found domestic studies on forest ecology rapidly increased since 2011. The most common research topic was "species diversity" over the past 20 years and "climate change" became a major topic since 2011. Based on CONCOR analysis, study subjects were grouped intoeight categories, such as "species diversity," "environmental policy," "climate change," "management," "plant taxonomy," "habitat suitability index," "vascular plants," and "recreation and welfare." Consequently, species diversity and climate change will remain important topics in the future and diversifying and expanding domestic research topics following global research trendsis necessary.

본 연구는 지난 20년(2001~2020)간 국내 산림생태 분야에 관한 전반적인 연구동향과 주요 연구 주제 분석을 통해 향후 연구의 방향성을 파악하고자 수행되었다. 이를 위해 한국교육학술정보원으로부터 국내 산림생태 관련 총 1015편의 논문 제목 및 키워드 데이터를 수집하여 빅데이터 분석프로그램 Textom과 UCINET을 활용하여 분석을 실시하였다. 분석 결과, 산림생태 관련 연구 논문수는 2006~2010년과 2011~2015년 사이에 증가율 137.6%를 나타내어 2011년 이후 급격히 증가한 것으로 나타났다. 단어빈도, N-gram 분석결과 지난 20년간 산림생태 분야의 주요 연구주제는 종다양성이었으며 2011년 이후 기후변화도 주요 연구주제로 출현하였다. CONCOR 분석결과 산림생태 분야의 주요 연구영역은 종다양성, 환경정책, 기후변화, 운영 관리, 식물분류, 서식지 적합성, 관속식물, 휴양복지로 구분되었다. 특히, 종다양성과 기후변화는 관련 정책 추진 현황을 고려할 때 향후에도 중요 연구주제로 다루어질 것이라 판단되며, 국외 사례를 참고하여 국내 실정에 맞는 연구주제의 다양화 및 범위 확대 등을 고려할 필요가 있다고 본다.
