Abstract: The study results indicated that the light hydrocarbons are mainly produced from the pinus pollen between 300~500℃,maximum at 350~450℃. When temperature is lower than 200℃,there are only traces of the light hydrocarbons produced.Higher 550℃,the light hydrocarbons are far less because of stronger thermal degradation. The light hydrocarbons consist offour components. The main component is aromatic serial compounde which consist of 1~4 aromatic rings. The aromatic com-ponent in the total light hydrocarbons is about 55. 17~65. 20%when the temperature is lower than 450℃. Hower,at over550℃ the light hydrocarbons consist almost all of aromatic compounds. The other components in the light hydrocarbons arenormal alkanes. alkyl cyclohexanes & alkyl cyclopentanes and long-chain fatty acid (or ester) serial compounds. Thesebiomarkers have been identified from oils, coals and other sedimentary organic matters which the main organic source are theterrestrial higher plants. So, this paper will provide the important imformations in recognising the hydrocarbon source tom-pounds of terrestrially crude oils (gases) and in the theory of the productive hydrocarbons during thermal maturation.
