人工林樟子松发热量与碳氢含量的关系分析

对东北林业大学哈尔滨实验林场人工林樟子松发热量和碳氢含量进行试验研究,结果表明,人工林樟子松发热量平均值为20.03 kJ/g,碳含量平均值为47.63%,氢含量平均值为6.39%;人工林樟子松各器官中,发热量和碳氢含量呈现出一致的变化趋势,即树叶各项值最高,树干木质部次之,其它依次为树枝木质部、树枝皮和树干皮;人工林樟子松各器官中,发热量与碳氢含量存在显著的相关关系。

Analysis of Relationship between the Calorific Value and the Carbon and Hydrogen Contents of the Pinus sylvestrisvar. mongolica Plantation

The calorific value, carbon content and hydrogen content of the Pinus sylvestris var. mongolica plantation in Harbin Experimental Forest Farm of Northeast Forestry University were studied in this paper. The results showed that the calorific average value was 20.03 kJ/g, the carbon average content was 47.63%, and the hydrogen average content was 6.39% of the P/nus sylvestris var. mongolica plantation. In addition the calorific average value and the carbon and hydrogen contents took on the same trend in all organs of the Pinus sylvestris var. mongolica plantation, of which the highest calorific value and the carbon and hydrogen contents existed in leaves while the trunk xylem, the branch xylem, and the trunk bark took the second, the third and the fourth places. There was significant hnear correlation between the calorific value and the carbon and hydrogen contents.
