花粉记录(约1090-1380年)在韩国西南部的咸平地区，从沼泽沉积物中提取的)展示了人类引起的植被变化和随后的环境变化。约1090-1340年间，松属和禾本科植物占主导地位。AD指的是人为造成的农田和以松树为主的森林。栽培禾本科植物的高代表性，农田杂草的频繁发生，落叶阔叶类群的低代表性，意味着水稻精耕细作。约1340年至1360年，暖温带常绿阔叶林的扩张和松树的撤退主导了森林。AD代表了气候引起的植被变化，而集约化耕作是持续的。种植的禾本科和农田杂草明显减少，河岸莎草科和蕨类孢子的急剧上升，从大约1360年到1380年。广告表示农田遭到破坏。与孢粉学证据一起，沉积学和历史学数据表明，农业活动的下降是由高丽王朝到朝鲜王朝政权更迭期间的洪水和社会不安全造成的。
A pollen record (ca. 1090–1380 cal. AD) from swamp deposits exhibits human-induced vegetation change and subsequent environment change in the Hampyeong area, southwestern Korea. The predominance of Pinus and Gramineae from ca. 1090 to 1340 cal. AD indicates human-induced cropland and Pinus-dominated forest. The high representation of cultivated Gramineae, regular occurrence of farmland weeds, and low representation of deciduous broadleaved taxa imply intensive rice cultivation. The expansion of warm temperate evergreen broadleaved forest and the retreat of Pinus dominated forest from ca. 1340 to 1360 cal. AD represent a climate-induced vegetation shift, while intensive cultivation was persistent. The conspicuous reduction of cultivated Gramineae and farmland weed, and the abrupt rise of riparian Cyperaceae and fern spores from ca. 1360 to 1380 cal. AD indicate devastation of the cropland. Along with palynological evidence, sedimentological and historiographical data suggest that this decline of agricultural activities was caused by inundation coupled with social insecurity during the period of regime change from the Goryeo Dynasty to the Joseon Dynasty.
