Abstract: With 27-year-old Pinus koraiensis provenance test plantations in Lushuihe Forestry Bureau in Jilin Province, we studied the variation patterns of growth, wood properties, biomass and carbon content and chose optimal provenances. There was significant or extremely significant difference among other characteristics provenances, except carbon content per plant, carbon content of tree crown and carbon content of 1.3 m. The growth traits were significant correlation with altitude, annual precipitation and sunshine hours. In wood properties, the correlation between the basic density and climatic and geographical factors is not significant, and the correlation between other characters and the geographical and climatic factors is complicated relatively. The carbon storage was significant or extremely significant correlation with latitude, altitude, annual precipitation and sunshine duration, and was not related significantly to the carbon content of root, lignin content, hemicellulose content and ash content. Five main components of variables affecting carbon were extracted and the accumulation contribution rate reached 83.741%. C' was only significantly positive correlation with the trees growth factor F₁. The carbon storage superior provenances score function was Z_k=C_k'+0.975*42.826%* F₁. Z_k value of Lushuihe, Linjiang and Dahailin provenances were in the top third, 2.929 8, 2.699 8 and 1.936 3, and the high carbon storage P.koraiensis provenances were chosen as the optimal provenances.
