摘要
为研究造林树种的碳汇效应,采用生长锥取样法对黑龙江省5个造林树种进行含碳率分析,并考察了含碳率与土壤性质的相关性。结果表明:5个造林树种含碳率在0.490±0.014(樟子松,S朝向)~0.439±0.018(杨树,N朝向)之间变化,在S(南)和N(北)朝向上,樟子松的含碳率均较高,其次为白桦和落叶松且含碳率相差不多,红松和杨树的含碳率较低。造林树种含碳率与土壤性质相关性研究表明:S朝向,樟子松含碳率与土壤容重呈显著正相关(R=0.571,P<0.05),与土壤总碳呈显著负相关(R=-0.552,P<0.05);白桦含碳率与土壤总碳之间呈显著正相关(R=0.558,P<0.05)。
In order to study the carbon sink effect of afforestation tree species, the carbon rate of five afforestation tree species in Heilongjiang Province was analyzed wi出 growth cone sampling method, and the correlation between carbon rate and soil properties was investigated. The results showed that the carbon rate varied between 0.490 ± 0.014 (Pinus sylvestris var. mongolica. S) and 0.439 ± 0.018 (Poplar, N). On south and norty orientations, the carbon rate of Pinus sylvestris was higher, followed by Betula platyphylla and larch, and the carbon rate of Pinus koraiensis and Populus was low. In the south orientation, significant positive correlation was found between carbon rate and soil bulk density (R=0.571, P〈0.05), while significant negative correlation was found between carbon rate and soil total carbon (R=-0.552, P〈0.05) of Pinus sylvestris var. mongolica; and significant positive correlation was found between carbon rate and soil total carbon (R=0.558, P〈0.05) of Betula platyphylla.
