The results indicate that:(1)Compare with the comparion, the soil physics character are improved after vegetation restortion , the soil unit weight in cyclobalanopsis glauca, Pinus elliottii, Robinia pseudoacacia , mixed forest and fire slash shrub separatly are 1.525g/cm~3, 1.426 g/cm~3, 1.625 g/cm~3, 1.482 g/cm~3, 1.423 g/cm~3. We can find the soil unit weight in other forest all bigger than the comparion (1.580 g/cm~3) except Robinia pseudoacacia .All these mean forest soil is looser and better capacity for aerated and dank.

结果表明：(1)植被恢复后林地土壤物理性质有良好的改进，青冈、湿地松、刺槐、混交林、火烧迹地灌丛容重分别为：1.525g/cm~3、1.426g/cm~3、1.625g/cm~3、1.482g/cm~3、1.423g/cm~3，除刺槐外其他林地均低于对照(1.580g/cm~3)，上述几种林分的孔隙度分别为：45.872%、51.956%、44.093%、50.485%、55.648%、47.228%，说明林地内土壤较对照更为疏松、通气透水能力更强，更有利于土壤微生物的活动，为研究区土壤肥力的提高奠定了基础。

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。
