The carbon storage and distribution property of the forestry of Pinus tabu-laeformis in natural reserve area of Helan Mountain of Ningxia
摘要
Abstract
It is significant for forest protection to slowing global warming. Because of the geographical location, climate, soil, spe-cies composition of the forest ecological system are different greatly, the carbon sink function are not identical respectively. Pinus tabulaeformis forest is one of the main forest type in the north of China, In order to learning the forestry carbon storage of Helan Mountain, s the tree of Pinus tabulaeformis was sampled and determined, throughing the field investigation and laboratory analysithe results show that average carbon content of the Pinus tabulaeformis is 51.91%. It is estimated that the total carbon storage of the forestry of Pinus tabulaeformis is 13.39 kg∙m-2, in which the trees, surface biomass and soil carbon storage are 2.98 kg∙m-2, 0.86 kg/m2 and 9.55 kg∙m-2 respectively. The soil stored 70%of the total carbon and it is main carbon pool of the forestry of Pinus tabu-laeformis in natural reserve area of Helan Mountain. Overall, the carbon sequestration capacity of coniferous forest was higher than that of broad-leaved forest, in the construction of carbon sequestration forest should be preferred conifer species. The forestry of Pinus tabulaeformis mainly distributed in the region that is located at 105.80°-106.15°E, 38.36°-39.00°N and with the height 2 000-2 400 m, and it is also the main organic carbon distribution zone of Helan Mountain. This region is the key area for the re-search of carbon balance and carbon trade.关键词
