Abstract：Compared with study in marine basins,study on the relationship between total organic carbon (TOC) content and sedimentation rate(SR)in continental lacustrine sediments is still in exploration phase,and the controlling mechanism of sedimentation on TOC especially needs intensive study. In this paper,astronomical cycles of the Upper Cretaceous in the southern borehole of Well CCSD-SK-1 were firstly identified with the cycle stratigraphy method; and then SR and the corresponding TOC of each window was calculated by moving-window spectral analysis method. Taking the Pr/Ph ratio as a redox condition index and δ13C of the ostracod shell as a paleo-productivity index,the relationship of SR and TOC in different environments and different paleo-productivity conditions in detail was discussed. Analyses show that TOC is mainly controlled by palaeo-productivity while the influence of SR is very little; in a high palaeo-productivity environment the TOC value is larger than 1% and less than 1% in contrast. But under the oxidation and low palaeo-productivity conditions,the TOC value tends to increase with SR when SR is less than 11,cm/ka and then decreases in a higher SR background.
