초록

광주광역시 화전 유적지의 습지 퇴적물에 화분분석, 수침목재 동정, 그리고 기초적인 퇴적물 분석 등을 수행하여 얻은 결과를 토대로 이 지역의 홀로신 중기 고식생 및 고기후를 유추해 보았다. 약 8200 ~ 6800년 전에는 홀로신 기후최적기에 비해 기후가 다소 건조하여, 참나무 개체수는 상대적으로 적었고 다양한 수목들이 함께 서식했다. 약 6800 ~ 5900 년 전은 홀로신 기후최적기로 온난 습윤한 기후가 강화되면서 참나무속에 유리한 환경이 조성되었으며 저습지의 면적이 감소하였다. 6100 년 전 경에는 한반도 남동부에서 홀로신 기후최적기의 지속으로 극상림에 가까운 삼림이 형성되었다. 약 5900 ~ 4700 년 전에는 기후가 냉량건조해지면서 극상림인 참나무숲의 면적뿐 아니라 전체 삼림 면적이 감소하였다. 이 시기 말미에는 기후의 일시적인 호전으로 오리나무숲이 팽창하였다. 마지막으로 약 4700 ~ 3300 년 전에는 오리나무의 세력이 감소하고 참나무가 우점했으며 상대적으로 건조한 기후가 지속되면서 삼림의 밀도는 낮았다.

The aim of this research is to infer paleovegetation and paleoclimate in the Hwajeon archeological site of Gwangju city during mid-Holocene through the analysis of pollen, waterlogged woods, and sediments. Between 8200 ~ 6800 years ago, relatively dry climate resulted in a weakened dominance of oak and high diversity of tree genus. During the Holocene climatic optimum period (6800 ~ 5900 years ago), oak forests expanded while wetland areas diminished as warm/humid climate intensified. Between 5900 ~ 4700 years ago, the entire forest area as well as oak climax forests was reduced due to a relatively cool/dry climate. However at the end of this period, oak forests expanded since a favorable climate condition temporarily resumed. Lastly, between 4700 ~ 3300 years ago, oaks dominated but alders were weakened. The density of forest was low because of a relatively dry climate in this period.
