武河湿地典型植被固碳能力分析

Analysis of Carbon Fixation Ability of Typical Vegetation in Wuhe Wetland

以临沂武河湿地典型植被芦苇、菖蒲为研究对象,研究其生物量、碳氮含量以及碳氮储量。结果表明:芦苇3、芦苇6处的生物量2.02、1.36 kg/m^2,菖蒲1的生物量1.99 kg/m^2要高于其他位点的生物量,芦苇3、芦苇6处的碳储量(17.44,12.19 kg/m^2)、氮储量(1.04,0.80 kg/m^2)菖蒲1的碳储量10.07 kg/m^2、氮储量0.62 kg/m^2均高于其他位点。说明武河湿地典型植被的碳氮储量与生物量有着密切的关系,芦苇、菖蒲生物量高的地方,其碳储量也高,固碳能力相对较高,同时氮储量会对湿地植被碳储量以及固碳能力带来影响。芦苇、菖蒲组织中氮含量总体分布于叶组织中,因为叶片是植物进行光合作用的重要器官,在进行光合作用时,通过吸收水分和无机盐的形式将N元素从根组织迁移并富集到叶组织中。

The Phragmites australis and Acorus calamus,typical vegetation of the Wuhe Wetland in Linyi,were used as research objects to study their biomass,carbon and nitrogen content,and carbon and nitrogen storage.The results showed that the biomass of reeds 3 and 6 was 2.02 and 1.36 kg/m^2,and the biomass of calamus 1 was 1.99 kg/m^2 higher than that of other sites.Carbon storage at reed 6(17.44,12.19 kg/m^2),nitrogen storage(1.04,0.80 kg/m^2),carbon storage of calamus 110.07 kg/m^2 The nitrogen reserves of 0.62 kg/m^2 were higher than other sites.This shows that the carbon and nitrogen reserves of typical vegetation in the Wuhe Wetland are closely related to biomass.Where the reed and calamus have high biomass,their carbon storage is also high,and their carbon sequestration capacity is relatively high.Impact on carbon sequestration capacity.The nitrogen content in reed and calamus tissues is generally distributed in leaf tissues,because the leaves are important organs for photosynthesis in plants.During photosynthesis,the element N is transferred from the root tissue and enriched to leaf tissue.
