Abstract

|
Pollen analysis to clear vegetational history of Korea was carried out on the deposits taken from the pit of the Miruksa site, south-western Korea (36°00´18´N, 127°1´12"E, 10m in alt.). This area has been known as the cool temperate zone(southern zone) according to Yim and Kira(1975). But, now we can not found the original vegetation because the area has been disturbed severely and almost area changed to cultivated land. The area is one of the most developed area in early agricultural stage of Korea.
By the pollen diagram, three local pollen zones are distinguished in this site, bottom to surface, as following.
IS-Ⅰ : Pinus-Quercus zone(140∼120 ㎝, sample 1 and 2)
IS-Ⅱ : Ulmus + Zelkova zone(120∼84 ㎝, sample 3∼6)
lS-Ⅲ : Pinus zone(84∼0 ㎝, sample 7∼13)
IS-Ⅰ is characterized by high values in frequences of Pinus, the temperate conifer and Quercus the cool temperate oak, and IS-Ⅱ zone by the decrease of Quercus and increase of Ulmus+Zelkova as ravine forest elements. IS-Ⅲ zone is characterized by Pinus, especially, based on the data of sample No. 9.
