摘要: 以中国东北样带(NECT)为依托,基于沿样带的野外观测和土壤实测数据,分析了沿样带的土壤碳、氮、磷的空间分布格局及其与年降水、年均温之间的关系。结果表明:样带内土壤有机碳、土壤全氮、土壤有效氮、土壤全磷、土壤有效磷沿经度均呈现出东高西低的分布趋势;降水量和温度对土壤碳、氮、磷的作用强度顺序分别为土壤有效氮、土壤有机碳、土壤全氮、土壤全磷和土壤有效磷;并建立了土壤有机碳、土壤全氮、土壤有效氮、土壤全磷、土壤有效磷与年降水、年均温之间的多项式回归方程,为样带陆地碳收支评估及养分循环提供基础资料。

Abstract: The carbon cycle is central to the global ecosystem, being inextricably coupled with climate, the water cycle, nutrient cycles, and the production of biomass by photosynthesis on land and in the oceans. It is very helpful for understanding the environment
