大庆市城市森林公园乔木林生物量及碳储量估算
|
摘要
由温室效应造成的全球气候变暖已引起全球广泛关注,森林作为地球上最大的碳库,在固碳释氧,减缓全球变暖等方面具有重要作用。通过实测大庆城市森林公园内5种树木共18 374株乔木的胸径和树高数据,采用异速生长方程对大庆市城市森林公园乔木生物量进行测定,并采用不同树种不同器官碳含量进一步估算碳储量。结果表明:(1)大庆市城市森林公园乔木层总生物量为12.76×10~3 t,单位面积生物量为227.50 t·hm~(-2),乔木层总碳储量为5 678.45 t,碳密度为101.22 t·hm~(-2);(2)城市森林公园各树种生物量及碳储量均为家榆>垂柳>银中杨>樟子松>云杉;(3)5种树种各器官生物量和碳储量分配均表现为干>根>枝>叶。
The global warming caused by the greenhouse effect has attracted worldwide attention. As the largest carbon pool on the earth,forests play an important role in carbon fixation and oxygen release and slowing global warming.Through measuring the DBH and tree height data of 18,374 trees in 5 species of trees in the urban forest park of Daqing City,the allometric models were used to measure the arbor biomass,and carbon contents of different tree species and different organs were used to further estimate carbon storage.The results showed that:(1)The total biomass of the arbor layer in the urban forest park of Daqing City was 12.76×10~3 t,the biomass per unit area was 227.50 t·hm~(-2),the total carbon storage in the tree layer was 5 678.45 t,and the carbon density was 101.22 t·hm~(-2);(2)The biomass and carbon storage of various tree species in urban forest park were as follows:Ulmus pumila L.>Salix babylonica>Populus alba x p.Berolinensis>Pinus sylvestris L.var.mongholica Litv.>Picea asperata Mast.(3)the proportional allocation of biomass and carbon stocks in all five tree species showed stem>root>branch>leaf.
