摘要: 以吉林省露水河林业局的27年生红松种源试验林18个种源为对象,对生长、材性、生物量、含碳率等性状的变异规律进行了研究,并选择了优良种源。研究结果表明,除单株含碳率、树冠含碳率及1.3m处木芯含碳率差异不显著外,其他性状种源间皆存在显著或极显著差异。树木生长性状与海拔、年降水量及日照时数达到显著相关水平;木材材性性状中,除基本密度与气候地理因素皆相关不显著外,其他性状与各地理气候因素的相关性比较复杂。碳储量与纬度、海拔、年降水量及日照时数达到显著或极显著相关水平,碳储量与树根含碳率、木质素含量、半纤维素含量及灰分含量皆相关不显著。影响碳储量的变量中提取了5个主成份,得到83.741%的累计贡献率。标准化后的碳储量C'只与树木生长因子F1极显著正相关,构造的碳储量优良种源得分函数:Zk=Ck'+0.975*42.826%*F1,Zk值以露水河2.9298、临江2.6998、大海林1.9363排在前三位,选为红松高固碳种源。

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 Zk=Ck'+0.975*42.826%* F1. Zk 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.
