以9个AMSHC年代为框架，以现代花粉研究为基础，UG04孔高分辨率孢粉记录重建了蒙古国中部8660 a BP以来的植被和气候变化：7800 a BP以前研究区植被以草原为主，气候温和略湿润，其中8350～8250aBP气候凉湿；7800～6860 a BP旱生植物增加，气候转向暖干；6860～3170 a BP半荒漠草原扩张，气候持续暖干；3170～2340 a BP旱生植被退缩，远山森林草原发育，气候转凉变湿，末期湿度条件达最佳；2340～1600 a BP气候较凉湿；1600 a BP以来气候波动较大，与区域古气候记录对比表明，蒙古国中部到中国西北干旱区可能存在持续干旱的中全新世气候。重建结果与GCM气候模式模拟结果有较好的呼应。此外，UG04孔孢粉记录揭示了若干气候变冷事件，部分可与北大西洋地区对应，但表现为冷湿。
文章在已有32-25 Ka B.P.期间黄土高原植被研究成果的基础上,初步勾画出黄土高原这一时期植被带的分布。与现今植被带分布相比,32-25 Ka B.P.期间森林草原带可能同时向南北扩张达到黄土高原的北界和南界,成为黄土高原植被的主体。现在兰州以西的草原带当时为山地针叶林。这些植被证据说明当时高原北部和西部可能比现在湿润,而南部比现在干。由于直接反映植被状况的资料有限,本文所进行的仅是定性的植被带描绘。
The Early Holocene paleoclimate in Bosten Lake on the northern margin of the Tarim Basin, southern Xinjiang, is reconstructed through an analysis of a 953 cm long core (BSTC2000) taken from Bosten Lake. Multiple proxies of this core, including the mineral components of carbonate, carbonate content, stable isotopic compositions of carbonate, Ca/Sr, TOC and C/N and C/S of organic matter, are used to reconstruct the climatic change since 8500 a B.P. The chronology model is made by nine AMS 14C ages of leaves, seeds and organic matter contained in two parallel cores. The climate was cold and wet during 8500 to 8100 a B.P. Temperature increased from 8100 to 6400 a B.P., the climate was warm and humid, and the lake expanded. The lake level was highest during this stage. Then from 6400 to 5100 a B.P., the climate became cold and the lake level decreased slightly. During the late mid-Holocene, the climate was hot and dry from 5100 to 3100 a B.P., but there was a short cold period during 4400 to 3800 a B.P. At this temporal interval, a mass of ice and snow melting water supplied the lake at the early time and made the lake level rise. The second highest lake level stage occurred during 5200 to 3800 a B.P. The climate was cool and wet during 3100 to 2200 a B.P., when the lake expanded with decreasing evaporation. The lake had the last short-term high level during 3100 to 2800 a B.P. After this short high lake level period, the lake shrank because of the long-term lower temperature and reduced water supply. From 2200 to 1200 a B.P., the climate was hot and dry, and the lake shrank greatly. Although the temperature decreased somewhat from 1200 a B.P. to the present, the climate was warm and dry. The lake level began to rise a little again, but it did not reach the river bed altitude of the Konqi River, an outflow river of the Bosten Lake.
