江西九连山不同海拔梯度土壤有机碳的变异规律
|
摘要
【目的】土壤类型、土壤层次及植被类型是土壤有机碳分布格局的重要影响因素,而海拔是对大尺度水热环境条件的再分配,涵盖了土壤类型和植被类型在小尺度上的剧烈变化信息,因而研究不同海拔梯度上土壤有机碳的变异规律对森林生态系统碳汇管理具有重要的意义。【方法】本研究选择九连山境内不同海拔高度(179～1 430m)的森林土壤为研究对象,通过分析植被类型、土壤类型、和不同层次的有机碳含量与碳储量等,揭示不同海拔高度有机碳的垂直分布规律及影响因素。【结果】土壤的前3层(0～40 cm)有机碳含量随着海拔的升高而呈现线性增大的趋势,而第4层(40～60 cm)和第5层(60～100 cm)则随着海拔的升高而逐渐的降低,土壤碳储量与海拔梯度的趋势与土壤有机碳与海拔梯度的趋势基本一致,但总碳储量与海拔梯度的趋势则呈先降低后升高的U形趋势;草甸土的前3层土壤有机碳含量和储量往往高于红壤和黄壤,并且随海拔升高,土壤类型从红壤、黄壤至草甸土的变化过程中,前2层(0～20 cm)有机碳含量和碳储量均存在逐渐上升,而其他层次则无显著差异;高海拔的杜鹃林和高山草甸表层土壤有机碳含量和碳储量往往高于较低海拔的其他植被类型,而高山草甸和次生阔叶林的0～100 cm总碳储量较高。【结论】土壤表层和植被类型的变化可能是导致九连山不同海拔梯度土壤有机碳变异规律的主要原因。在全球气候变暖的情形下,高海拔地区的表层土壤可能随着温度的上升而增加碳排放。
[Objective]Soil type,soil layer and stand type are considered as major factors affecting the distribution of soil organic carbon. Meanwhile,an altitudinal gradient is a redistribution of hydrothermal conditions at large-scale environments,and often involve the variations of soil and vegetation types at small scale. Therefore,there is an important significance for carbon sequestration management in forestecosystem to explore the variations of soil organic carbon along an altitudinal gradient( 179-1 430 m).[Method]Twenty soil profiles distributed with five soil layers along an altitudinal gradient in Jiulian Moutain were sampled. Moreover,vegetation type,soil type,soil organic carbon content and soil carbon storage were recorded for these soil samples to explore the vertical distribution and influencing factor of soil organic carbon along an altitudinal gradient. [Result] The organic carbon content of top three soil layers( 0-40 cm) increased linearly with the increase of elevation,whereas that of the bottom two layers( 40-60 cm and 60-100 cm) decreased linearly with the increase of elevation. The pattern of soil carbon storage with elevations was similar with that of soil organic carbon content. However,there was a"U"shape between total soil carbon storage and elevation; Soil organic carbon content and carbon storage of top three soil layers in meadow soil were generally higher than those in red soil or yellow soil,the organic carbon content and carbon storage of top soil layer( 0-20 cm) increased with the altitudinal gradient from red soil,yellow soil to meadow soil,meanwhile there was no significant difference among other layers. Soil organic carbon content and carbon storage of top three soil layers for Rhododendron woods and alpine meadow in high elevation were generally higher than those for the other vegetation types in low elevation,and there was the highest total carbon storage with 0-100 cm in alpine meadow and secondary broadleaved forest. [Conclusion] These results indicate that variations of top soil layer and vegetation types are the major factors to drive the variations of soil organic carbon along an altitudinal gradient in Jiulian Mountain of eastern China. The carbon emission of top soil layers in high elevation may increase with the increase of air temperature under the global warming.
