摘要:
研究生物质能源树种千年桐人工林乔木层生物量特征及其分配规律。采用样地调查和标准木收获法测定2 a、3 a、5 a、7 a、9 a生千年桐人工林乔木层生物量,建立千年桐人工林乔木层生物量回归模型,其全株的相关系数为0.980 1,其他组分相关系数均在0.909 3以上,具有良好的相关性。结果表明:2 a、3 a、5 a、7 a、9 a生林分乔木层生物量分别为41.162 t/hm2,51.15 t/hm2,58.656 t/hm2,114.005 t/hm2,134.894 t/hm2,9 a生林分乔木层生物量是分别7 a,5 a,3 a,2 a生林分的1.183倍,2.300倍,2.637倍,...
Abstract:
The biomass characteristics and distribution in the arbor layer were focused on in the study of Aleurites Montana as a bioenergy species. The arbor layer biomass of Aleurites Montana plantations of 2 a, 3 a, 5 a, 7 a and 9 a were determined by the method of field study and standard tree yield. Meanwhile, in the regression equation of arbor layer biomass as W=a(D2H)b, the correlative coefficient of total stem was 0980 1 and those of other organs were above 0909 3, showing positive correlation. The results showed that the arbor layer biomass of 2 a, 3 a, 5 a, 7 a and 9 a Aleurites Montana were determined respectively as 41162 t/hm2, 5115 t/hm2, 58656 t/hm2, 114005 t/hm2 and 134894 t/hm2 The arbor layer biomass of 9 a Aleurites Montana was respectively 1183, 2300, 2637 and 3277 times more than that of 7 a, 5 a, 3 a and 2 a. In arbar layer biomass distribution, the stems of 9 a occupied the highest proportion as 4109% while those of 2 a occupied the lowest as 3854%; the branches of 7a occupied the highest as 261% while those of 5 a occupied the lowest as 228%; the leaves of 5 a occupied the highest as 1372% while those of 7 a occupied the lowest as 1038%; the roots of 7 a occupied the highest as 2368% while those of 9 a occupied the lowest as 2152%. Stem biomass contributed the most in arbor layer biomass and the biomass of stems, branches, leaves and roots obviously presented the increasing tendency with the aging of the stand.
