摘要
为探究小清河滨岸带土壤中碳氮组分的空间变化规律,分析小清河流域土壤碳氮组分对河流的影响,该文采集小清河不同类型滨岸带(林地、草地、荒地、林草混合)的土样,测定其基本理化性质及总有机碳、溶解性有机碳、微生物生物量碳、总氮、硝氮、氨氮。研究结果显示,发现碳氮不同形态的空间分布规律总体均表现为从水滨到高地逐渐递减,经冗余分析发现,不同时期不同形态的碳氮与土壤基本理化性质、常量元素等关系密切。
To explore the spatial variation of carbon and nitrogen in the soil composition,and analyze the effect of soil carbon and nitrogen component on Xiaoqing River,different types of riparian zone such as forest land,grassland,desert,grassland of soil samples were collected,and the basic physical and chemical properties and total organic carbon,soluble organic carbon,microbial biomass carbon,total nitrogen,nitrate nitrogen,ammonia nitrogen were measured.The results showed that the spatial distribution of different forms of carbon and nitrogen generally showed a gradual decrease from the waterfront to the highlands,and the redundancy analysis showed that the different forms of carbon and nitrogen in different periods were closely related to the basic physical and chemical properties and constant elements of the soil.
