This study was carried out in the peatland for estimating the paleoenvironment based on the analysis from its fossils plant and radiocarbon at the Hwayang-ri, Hyeondeok-myeon, Pyeongtaek-city, South Korea. Variety of fossil was collected from the peatland which could discriminated with naked eye and sorted into seeds, leaves, stems from four-stage of standard sieve. During analysis for the large plant fossil within the peatland, the dead plants were largely divided into 3 fossil zones according to its peatland. In the fossil zone Ⅲ(the oldest layer; 6,970~6,070 yr C14 B.P.), the observation of leaves of hydrophyte such as Trapa sp. and stems of Alnus japonica which appeared in wetland means that the environment was influenced by the climate changes such as rainfall increasing and sea level rise. In the fossil zone Ⅱ(the middle layer; 6,070~5,800 yr C14 B.P.), the occurrence of Gramineae, Cyperaceae and Fagaceae indicate that the environmental condition might be more or less dry by decreasing rainfall and drop in sea level. The fossil zone Ⅰ(the recent layer; 5,800~4,540 yr C14 B.P.) where lots of herbaceous plants, increasing of Fagaceae, decreasing of A. japonica. and distribution of Pinaceae were showed, was inferred to be repeated both dry and wet environment due to human disturbance.

경기도 의왕시 포일동의 후기 플라이스토세 퇴적층에 대한 화분분석 결과, 초본류 및 양치식물로 이루어진 저층의 발달과 함께 침엽수-낙엽성 활엽수 혼효림이 분포했던 것으로 나타났다. 기후조건을 반영하는 식생조성의 변화가 인지되는데, 약 43,100년 전-41,900년 전 시기에는 오늘날보다 다소 추운 한랭한 온대 기후하에서 초지식생을 수반한 침엽수-낙엽성 활엽수 혼효림이 발달하였다. 약 41,900년 전-41,200년 전 동안에는 양치식물 저층의 발달과 함께 침엽수-낙엽성 활엽수 혼효림 내에서의 아한대성 침엽수의 감소와 온대성 낙엽 활엽수의 증가가 나타나는데 이는 기후조건의 온난화를 지시한다. 약 41,200년 전-39,700년 전 시기에는 기후 한랭화에 따른 아한대성 침엽수의 증가와 식생밀도의 감소가 나타난다.
