The study has shown:(1) With increasing sediment depth and the woody giblets, the total organic carbon, the extraction of benzene , the total humic acids and the unhydrolyte are enhanced, while the hydrolyte is decreasing.(2) According to the GC-MS analysis, n-alkane,n-alkan-2-ones and n-alkanones are composed mainly of long-chains,such a result is thought to be characteristic of a herbaceous input from 2300a.B.P. n-alkanones exist in the samples may be considered as the evidence of microorganisms activity.(3) It is showed that the lipids is more sensitive to the climate change than the floristic. The proxy of the pollen spore of the peat stratum is different from the normal environment proxy. It is one of the main reasons that the sensitivity difference of the bog vegetation reacting to the climate isn't accordant with the log of the fat molecule fossil and biology fossil.(4) The transformation of the peat organic carbon is under the influence of temperature,acidity,organic material constituting, etc, and it showed the up-trend with the depth. In the short-term scale, the conversion of the peat organic carbon is effected by seasonal water,regional climate and vegetations; while in the long-term scale, it is controlled mainly by the climate.(5) According to the comparing the orderliness of organic compound,vegetation giblets with the depth to the characteristics of the peat molecule fossil with the section, in the development of this peatmire, 1500a B.P(210cm)is regard as the borderline of the late Holocene, the keynote of the front period is warm with several cold fluctuations, and the trend of the back period is dry and cold although there were several fluctuations.
研究表明:(1)随深度的增高及植物残体中木本残体的增多,总有机碳、苯萃取物、总腐植酸、不被水解物含量逐渐增高,而易水解物含量减少;(2)GC- MS分析显示,正构烷烃,直链烷基2-酮和正烷醇均以长链组分为主,揭示了该泥炭柱剖面2347a.B.P的母源输入以草本植物为主;甲基酮类和短链正烷醇的存在是微生物活性很大的生物证据;(3)通过有机分子标志物与孢粉、植物残体等指标的对比研究表明:脂类化合物对气候变化的反映要比植物种灵敏得多,不同沼泽植物对气候变化的敏感性的差异是脂类分子化石记录与生物大化石结果很难一致的主要原因之一;(4)泥炭有机碳的转化受到温度、酸度、有机物质组成等很多因素的影响,短时间尺度,泥炭有机碳的转化受季节性降水、地方气候和植被等因素的影响;长时间尺度,泥炭地有机碳的转化,受气候条件控制;(5)总结泥炭分子化石特征、泥炭有机质各组分含量及植物残体组成随深度的变异规律,分析结果显示该泥炭地层形成过程中,1500a B.P(210cm)可作为划分前后晚全新世的界线,前期的基调是气候偏暖,但又有几次偏干冷气候的反复,后期气候以干冷为主,其间虽有几次上升波动,但整体趋势不变。

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.

Based on the results simulated by PRECIS (Providing Regional Climates for Impacts Studies), which is developed in the Hadley Centre for Climate Prediction and Research, changes of surface air temperature and precipitation under SRES B2 scenario in South China during 2071~2100 are analyzed. It is shown that, compared to baseline (1961~1990), surface air temperature in 2071~2100 would increase by 2~4℃, precipitation in summer would increase in the north part to 22°N, while the precipitation in winter would decrease in the whole areas of South China. The climate trend of the surface air temperature would be positive, however the climate trend of the precipitation would be negative, the occurrence frequency of extremely high temperature events and extremely heavy precipitation events would increase.
