The palaeoenvironmental conditions of Pliocene sedimentation were rather different in the southern, central, and northeastern parts of Ukraine. In the southern regions, the transgressional–regressional phases of the Kimmerian marine basin influenced the vegetation cover. The Pliocene vegetation of the central and northeastern regions is driven by long‐term and short‐term climatic changes. The reconstruction of Early Pliocene vegetation is carried out according to the results of spore‐pollen analysis of Lower Pliocene marine and continental deposits exposed in 12 sections located within the Ukrainian Plain. Pollen data show, that regardless of the differences in palaeoenvironmental conditions in the studied regions, the general patterns of changes in vegetation composition of the plain part of Ukraine during the Early Pliocene can be clearly traced. The presently obtained patterns are closely related to global geological and climatic events. The Pliocene climatic optimum is timed to the middle Kimmerian. At that time, warmth‐loving broadleaf taxa occurred in the vegetation of the Ukrainian Plain. The developments of the Neogene vegetation of Ukraine clearly reflect the graduate cooling from the Miocene to Pliocene, and from the Early to Late Pliocene. In the composition of the Late Pliocene vegetation of Ukraine, thermophilic elements decreased in comparison to the Early Pliocene.

乌克兰平原上新世沉积物形成的古环境条件和植被覆盖动态

在乌克兰的南部，中部和东北部，上新世沉积的古环境条件差异很大。在南部地区，Kimmerian海盆的海侵-海退阶段影响了植被覆盖。中部和东北地区的上新世植被受长期和短期气候变化的驱动。上新世早期植被的重建是根据对位于乌克兰平原内12个区域的下新世海洋和陆相沉积物的孢粉分析结果进行的。花粉数据表明，无论所研究地区的古环境条件如何，都能清楚地追踪到上新世早期乌克兰平原部分植被组成的总体变化规律。目前获得的模式与全球地质和气候事件密切相关。上新世气候最适时间定在中基米期。当时，乌克兰平原的植被中出现了喜欢保暖的阔叶类群。乌克兰新近纪植被的发展清楚地反映了从中新世到上新世，以及从上新世到晚上新世的逐渐降温。乌克兰的上新世晚期植被组成中，与上新世早期相比，嗜热元素减少。乌克兰新近纪植被的发展清楚地反映了从中新世到上新世，以及从上新世到晚上新世的逐渐降温。乌克兰的上新世晚期植被组成中，与上新世早期相比，嗜热元素减少。乌克兰新近纪植被的发展清楚地反映了从中新世到上新世，以及从上新世到晚上新世的逐渐降温。乌克兰的上新世晚期植被组成中，与上新世早期相比，嗜热元素减少。
