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.
