연구지역의 지형은 해안과 인접한 소규모의 곡저평야에 속한다. 이 곡저평야는 낮은 구릉지 사이 개석된 곳에 충적물이 매적되어 형성되었다. 본 연구에서는 탄소안정동위원소비 분석과 토양유기탄소 분석을 이용하여 과거의 기후환경 복원을 시도하였다. I 시기(약 $6,600{pm}60;yr$ B.P.$-5,350{pm}60;yr$ B.P.)는 전반적으로 온난하고 습윤한 기후환경이었으나, 건습변화에 있어서는 약건조(또는 약습윤)${ ightarrow}$습윤의 미변화가 감지된다. II 시기(약 $5,350{pm}60;yr$ B.P.-2,200 yr B.P.)는 현재와 비슷한 온난습윤한 기후환경을 나타낸다. $4,720{pm}60;yr$ B.P.와 $4,210{pm}50;yr$ B.P. 사이는 전체 퇴적층 중 가장 습윤했던 것으로 파악된다. $4,210{pm}50;yr$ B.P. 이후에는 점차 습윤에서 약습윤(또는 약건조)환경으로 이행하는 과정이 나타난다. III 시기(약 2,200 yr B.P.$-210{pm}60;yr$ B.P.)는 앞선 두 시기와 확연히 구분되며, 약습윤(또는 약건조)의 기후환경을 나타낸다.
The landform of the study area is defined as a small-scale alluvial plain in the valley bottom adjacent to the coast. By the aggradation of alluvial materials, this valley bottom plain was formed in dissected parts of low hills. For the purpose of reconstructing the palaeo climate environment in this study, $delta^{13}C$ analysis and soil organic carbon analysis are therefore employed. Main results of this study are as follows: Section I: the period of $6,600{pm}60yr$ B.P.$-5,350{pm}60yr$B.P. was mostly in warm and humid climate environment. A little changes of the humid environment are detected as subdry (or sub-humid)${ ightarrow}$humid in terms of the dryness and wetness. Section II: the period of $5,350{pm}60yr$ B.P.-2,200 yr B.P. was in warm and humid climate environment, which is similar to the present. However, The sediments between $4,720{pm}60yr$ B.P. and $4,210{pm}50 yr$ B.P. experienced the most humid climate environment of all studied sedimentary layers. After $4,210{pm}50 yr$ B.P., the environment started to change from the humid to the sub-humid (or sub-dry) climate. Section III: the period of 2,200 yr B.P.$-210{pm}60 yr$ B.P. was distinguish from previous two sections as the environmental changes to sub-humid (or sub-dry) climate was apparent.
