从中国福建省屏南县获得的高分辨率花粉记录为了解过去 1300 年来生态系统变化的性质以及人类干扰的相对重要性提供了新的见解。花粉和稳定碳同位素数据表明，在大约 800 cal BP 之前，研究区域被天然森林覆盖，以常绿阔叶树（栲树和栎树）为主。在大约 800 cal BP 之后，这种原始植被逐渐被次生植被所取代。自~800cal BP以来禾本科花粉的增加和~450cal BP之后松属花粉的急剧增加清楚地表明了人类影响的扩大，反映了农业的扩张以及原始植被改变后现在广泛分布的马尾松的演替。分类多样性分析还表明，人类干扰期间的植物区系多样性高于记录的早期部分，这一现象在人类活动增加的温带花粉记录中观察到。
A high-resolution pollen record obtained from Pingnan County, Fujian province in China, provides new insights into the nature of ecosystem changes and the relative importance of human disturbances during the last 1300 years. Pollen and stable carbon isotope data indicate that prior to about 800 cal BP the study area was covered by a natural forest, dominated by evergreen broad-leaved trees (Castanopsis and Quercus). This primeval vegetation was then progressively replaced by the secondary vegetation after ∼800 cal BP. Increases of Gramineae pollen since ∼800 cal BP and a sharp rise in Pinus pollen after ∼450 cal BP clearly express the expansion of human impacts, reflecting the expansion of farming and the succession of a now-widespread Pinus massoniana after alteration of the primeval vegetation. Taxonomic diversity analysis also shows that the floristic diversity is higher during the period of human disturbances than in the earlier part of the record, a phenomenon that has been observed in temperate pollen records where human activities increased.
