利用方式对青海省高寒草甸土壤可溶性有机质光谱学特性的影响
|
摘要
为深入了解不同利用方式对青海省高寒草甸土壤可溶性有机质含量和结构特性的影响,以次生沙棘林地、退耕还林地、农田和天然放牧地等4种利用方式土壤作为对象,研究了其0～10cm和10～20cm土层可溶性有机质含量、紫外-可见光光谱及其特征参数、荧光光谱及其特征参数等。结果表明,0～10cm土层可溶性有机碳和有机碳含量由高到低的顺序为天然放牧地>退耕还林地>次生沙棘林>农田。10～20cm土层中的可溶性有机碳及有机碳含量在退耕还林地和次生沙棘林中较高。有机碳含量和可溶性有机碳含量及其复杂程度随土层的加深而降低。天然放牧地土壤可溶性有机质的芳香化程度和腐殖化程度较高,含有较多的多环芳烃。研究结果指出,天然放牧地土壤可溶性有机质的结构更为复杂,稳定性更强,对维护青海省高寒地区碳库平衡和生态稳定有积极作用。0～10cm土层土壤可溶性有机质的结构更为复杂。
Soil dissolved organic matter is the most active component of the global carbon cycle.It plays an important role in the terrestrial ecosystem.In order to explore the effects of utilization patterns to the content and structural characteristics of soil dissolved organic matter of alpine meadow in Qinghai province,the contents of soil dissolved organic carbon,ultraviolet-visible spectroscopy,SUVA_(254),SUVA_(280),f_(450/500),HIX and synchronous fluorescence spectroscopy in 0 to 10 cm and 10 to 20 cm soil layers under 4 different utilization patterns,including secondary seabuckthorn forest,returning farmland to forest,farmland and natural pasture,were measured.The results showed that the variation of soil dissolved organic carbon and organic carbon contents in 0 to 10 cm layers performed a similar pattern,i.e.natural pasture>secondary seabuckthorn forest>returning farmland to forest>farmland.However,soil of returning farmland to forest and secondary seabuckthorn forest in 10 to 20 cm layers had higher dissolved organic carbon and organic carbon contents.The contents of organic carbon and dissolved organic carbon decreased with the depth of the soil layer.The same as the complexity of soil dissolved organic matter.The soil dissolved organic matter in the soil of natural grazing land had a higher degree of aromatization and humification,and had more polycyclic aromatic hydrocarbons.The results indicated that the structure of soil dissolved organic matter of natural pasture was more complicated and more stable.It could give a positive effect on maintaining the balance and ecological stability of the carbon pool in the alpine region of Qinghai province.The structure of soil dissolved organic matter in 0 to 10 cm layers was more complicated.
