Abstract：Milankovitch theory is an important tool in constraining time in the palaeoenviorment analysis. In this study，the geophysical logs of the Late Permian No.17 Coal in Nuodong，Puan of Guizhou Province and No.10 Coal in Tianyou，Fuyuan of Yunnan Province are analyzed employing spectral analysis.The result shows that the mineral matter content(ash yield)of the coal was possibly influenced by 123ka(eccentricity)，35.6 ka(obliquity)and 21.2 ka(precession)Milankovitch cycles.Using this timeframe，the Lopingian tropical peatland carbon accumulation rate is calculated to be 54.3～77.0 gC/（m2·a），which is expected to correspond to a NPP of 543～1540 gC/（m2·a）. A comparison of NPP and temporal atmospheric composition among the Late Permian，Late Carboniferous and modern time indicates that the Late Permian NPP calculated is consistent with geochemical and palaeobotanical models，supporting a proposal that terrestrial productivity is mainly controlled by temporal atmospheric O2 and CO2 levels.
