Latvia Lake provides one of the few high-resolution palaeoenvironmental records from southeastern Primor'ye. It traces basin, vegetation and climate histories over the past c. 8.6 ka. The Latvia basin experienced four phases, two of which involved frequent shifts amongst lake, lagoon and bay settings (c. 8.6–7.0 cal. ka BP and c. 2.1 cal. ka BP–present). A sandbar was present between c. 7.0 and 6.9 cal. ka BP. The longest interval of Latvia basin stability was from c. 6.9–2.1 cal. ka BP when the basin was a lagoon of varying salinities. Quercus-broadleaf forests characterized the regional vegetation throughout the past c. 8.6 ka. Variations in thermophilous species (e.g. Juglans,Carpinus,Ulmus,Tilia,Syringa) and Pinus koraiensis reflect shifts in temperature and moisture during the Middle Holocene. A period of warmest climate occurred c. 8.6–5.1 cal. ka BP with wettest conditions from c. 7.5–4.3 cal. ka BP, although all changes in temperature and precipitation were gradual. The Latvia Lake results indicate that changes in Middle to Late Holocene climates were linked more closely to shifts in the East Asian Summer Monsoon and less so to sea level oscillations. This investigation demonstrates that lakes of coastal Primor'ye can provide reliable palaeovegetation and palaeoclimate records despite their changing depositional environments.

滨海滨海边疆区的湖泊发展和植被历史：对俄罗斯远东东南部全新世气候的影响

拉脱维亚湖是滨海边疆区东南部为数不多的高分辨率古环境记录之一。它追溯了过去的盆地、植被和气候历史c。 8.6 卡。拉脱维亚盆地经历了四个阶段，其中两个涉及频繁的变化之中湖，泻湖和海湾的设置（角 8.6-7.0 CAL嘉BP和角 2.1 CAL。KA BP至今）。c之间存在沙洲。 7.0 和 6.9 卡路里 卡 BP。拉脱维亚盆地稳定的最长间隔是从c。 6.9–2.1 卡路里 ka BP 当盆地是不同盐度的泻湖时。栎属阔叶林在过去c. 中以区域植被为特征。 8.6 卡。在喜温物种（例如变化胡桃，鹅耳枥，榆，椴树，丁香）和红松反映中全新世期间在温度和湿度变化。出现了最温暖的气候时期C. 8.6–5.1 卡路里 ka BP 在最潮湿的条件下来自c。 7.5–4.3 卡路里 ka BP，尽管温度和降水的所有变化都是渐进的。拉脱维亚湖的结果表明，全新世中晚期气候的变化与东亚夏季风的变化更密切相关，而与海平面波动的相关性较小。这项调查表明，滨海滨海边疆区的湖泊可以提供可靠的古植被和古气候记录，尽管它们的沉积环境不断变化。
