Abstract

To systematically monitor changes in agricultural plant flora resulting from climate change and agricultural environmental shifts, it is necessary to establish an appropriate number of survey sites based on scientific evidence. This study aimed to determine the minimum number of survey sites required for long-term monitoring of plant flora in major agricultural land types in Korea: paddy fields, upland fields, and orchards. Plant taxa accumulation curves were derived for each habitat type to propose the minimum number of sites for efficient nationwide surveys, and the overlap of plant taxa among habitat types was visualized using Venn diagrams. Analysis showed that upland fields required the fewest sites, identifying over 90% of the taxa with just 10 sites, followed by paddy fields (24 sites) and orchards (28 sites). When integrating all agricultural land types, over 90% of the taxa were identified with 56 sites. Venn diagram analysis clearly showed the number of taxa unique to each agricultural land type and those common across multiple agricultural land types. These findings provide a scientific basis for establishing a long-term monitoring system for the agricultural plant flora of Korea and are expected to contribute to the formulation of agroecosystem management policies in response to climate change.

기후변화와 농업환경 변화로 인한 농경지 식물상 변화를 체계적으로 모니터링하기 위해서는 과학적 근거에 기반한 적정 조사 지점수의 설정이 필요하다. 본 연구는 한국의 주요 농경지 유형인 논, 밭, 과수원에서 식물상 장기모니터링에 필요한 최소 조사 지점수를 산정하는 것을 목표로 하였다. 각 서식지 유형별로 식물 분류군 축적 곡선을 도출하여 효율적인 전국 단위 조사를 위한 최소 조사 지점수를 제시하였고, 서식지 간 분류군 중복성을 벤 다이어그램으로 시각화하였다. 분석 결과, 밭은 단 10개 지점만으로 전체 분류군의 90% 이상을 식별할 수 있어 가장 적은 조사 노력으로 높은 종 파악률을 보였으며, 논은 24개, 과수원은 28개의 지점이 필요하였다. 세 가지 농경지 유형을 통합한 경우, 전체 분류군의 90% 이상을 파악하기 위해서는 56개 지점의 조사가 필요한 것으로 나타났다. 벤 다이어그램 분석을 통해 농경지 유형별 고유 출현 분류군과 복수 농경지 유형에 공통으로 출현하는 분류군 수가 명확히 확인되었다. 본 연구 결과는 한국 농경지 식물상의 장기적 모니터링 체계 구축을 위한 과학적 기초자료를 제공하며, 기후변화에 대응한 농업생태계 관리 정책 수립에 기여할 것으로 기대된다.
