From 6860 to 3170 cal.yr BP,semi-desert steppeexpanded,regional montane forest steppe retreated,suggesting a prolonged warm and dryclimate.Between 3170 and 2340 cal.yr BP,regional forest steppe expanded whereassemi-desert steppe retreated,indicating the climate became cool and wet gradually and thehumidity reached the maximum at the end of this stage.During 2340～1600 cal.yr BP,Poaceae steppe dominated whereas wetland meadow expanded and the montane forest stepperetreated,suggesting a cool and wet climate prevailed,wormwood grass steppe prevailed andthe climatic instability increased after 1600 cal.a BEThe climate and environmental reconstructions by pollen were supported by the diatomrecords.A relative high lake level and moister climate prevailed between 8660 and 7230 cal.yr BP as inferred by the dominance of planktonic diatom genera and high planktonic/benthicratio (〉40).low lake level and dry climate sustained during 7230～2330 cal.yr BP assuggested by the low abundance of planktonic diatom and low planktonic/benthic ratio ～20and the lake returned to high level during 2330～930 cal.yr BP as inferred by there-dominance of the planktonic diatom and the high value of palnktonic/benthic ratio.The pollen-based climate reconstruction was also consolidated by the grain size andPediastrum concentration records.

Ugii Nuur湖周围现代孢粉研究表明：松属为空气传播的外来花粉，其含量变化可能指示了远山森林草原发育状况；禾本科具显著低代表性，母体植物建群时含量通常在10％以下：藜科花粉含量可以指示区域气候干旱程度。2、以现代孢粉研究为基础、可靠AMS~(14)C年代为框架，Ugii Nuur孢粉记录高分辨率地重建了蒙古国中部地区过去8660 cal.yr BP以来的植被和气候变化。8660～7800 cal.yr BP研究区植被为禾草草原，湖畔及河谷低地发育苔草草甸，远山发育松属针叶林和森林草原，气候温和略湿润；其中8350～8250 cal.yr BP湿生草甸扩张，旱生植物成分减少，气候凉湿。7800～6860 cal.yr BP旱生成分增加，气候转向暖干。6860～3170 cal.yrBP半荒漠草原扩张，远山森林草原退缩，山地草原和河谷及湖畔湿生草甸退缩，气候持续暖干。3170～2340 cal.yr BP半荒漠草原退缩，远山森林草原扩张，气候转凉变湿，末期湿度条件达最佳。2340～1600 cal.yr BP禾草草原发育，湖畔及河谷低地湿生草甸扩张，远山森林草原略有退缩，气候总体较凉湿。1600 cal.yr BP以来研究区发育禾草-冷蒿草原，气候波动较大。

Through the analysis and contrast between HM core and Dh core, combined with the data of AMS14C, six pollen assemblages were ploted Out. At the mean time, six stages about the vegetation change and climate fluctuation were rebuild. In addition, there were three sub-assemblages ploted out in the Atlantic period, Sub-Boreal period and Sub-Atlantic period, which reflected the less vibration of the large-scale climatic change. Pollen assemblage dominated by Concentricystes in the hard and green clay of late Pleistocene can make it sure that the hard green clay layer was formed by water.

通过对上海地区鹤鸣孔和东海1井两个钻孔进行孢粉分析鉴定和对比，结合AMS14C测年等资料，划分出了6个孢粉组合带，恢复了本区的植被演化和气候波动的6个阶段，对鹤鸣孔的大西洋期、亚北方期和亚大西洋期各划分出了两个孢粉组合亚带，反应了大气候环境下气候的次一级波动，在晚更新世晚期的硬绿色粘土中还发现了以环纹藻为主的孢粉组合，从孢粉学角度上证实了这一硬绿色粘土层&水成沉积&的观点。

After complete regional analogue, it is discovered that the palaeoclimate and palaeoenvironment in Tontso is entirely comparative and consistent with the synchronous lakewater retreating of Zhaduixiong spits in Zabuye Lake basin, with palaeoclimate changes recorded by pollen in adjacent Zhabuye Lake, with Holocene palaeoclimate environment indicated by drilling-hole in Bangong Co, with palaeoclimate significance traced by δ〓O value in Qinghai Lake and Siling Co, with pollen- and diatom-inferred climatic change in Longmu Co and Sumxi Co, and with the palaeoclimate framework during the 5〓 Level Arid Extension Period of Quaternary arid center of Western China.

对比研究发现，洞错的古气候环境，与同期相邻的扎布耶湖湖水退缩遗迹和花粉记录的古气候变化、班戈湖钻孔所揭示的全新世古气候环境、色林错δ〓O值所揭示的气候意义、龙木—松西错的孢粉和硅藻提供的古气候古环境信息以及第四纪西部干旱中心在第5级干旱扩张期中的古气候格局，它们的气候环境变化总体上均有可对比性和一致性。
