Palynological Studies on Postglacial Age in Eastern Coastal Region, Korea Peninsula

Abstract

In these analyses the author treats two peat samples (Jumoonjin and Bangeojin) and one boring core of alluvium (Pohang) from eastern coastal region of Korean Peninsula (Fig. 1, 6, 7, 8).The forest change in eastern coastal region, Korean Peninsula, since the Late Glacial Age is divided into two stages and three substages. It may be summarized as follows.I; Quercus Stage (10, 000-6, 000y. B. P.)II; Pinus-Quercus Stage (6, 000y. B. P. -present)IIa; Lower Pinus dominant Substage (6, 000-4, 000/3, 000 y. B. P.)IIb; Pinus, Quercus Substage (3, 000/4, 000-2, 000y. B. P.)IIc; Upper Pinus dominant Substage (2, 000y. B. P. -present)The change of the forest in study area was controlled mainly by climate, partly by sea level change and human activities.From forest change of Postglacial Age, the author considered that the Stage I and Substage II (b) were under relatively humid climate, but the Substage II (a) and II (c) were under relatively dry climate.
