不同类型土壤有机碳含量的对比研究（摘要）

目的]研究不同类型土壤有机碳含量及影响因素。方法]以武夷山不同类型土壤为研究对象,进行土壤有机碳含量及基本理化性质的测定,分析不同类型土壤有机碳含量与土壤基本理化性质、海拔高度、年均气温等因素之间的关系。结果]武夷山不同类型土壤的有机碳含量在14.91～112.34g/kg;土壤有机碳与速效养分（速效氮、速效磷和速效钾）和全氮呈正相关,与全氮呈正相关关系和土壤有机碳与海拔高度、年均气温呈显著指数关系。结论]武夷山不同类型土壤有机碳含量受土壤理化性质、海拔高度及年均气温影响显著。

Comparison of Soil Organic Carbon Content in Different Soil Types of Wuyi Mountains

Objective] The aim was to explore the soil organic carbon(SOC)content from different types of soil and its influencing factors.Method] Soil samples were collected from Wuyi Mountains,and the physical and chemical properties were measured and the relationship between SOC content and soil physical and chemical properties,altitude,average annual temperature was analyzed.Result] SOC content ranged from 14.91 to 112.34 g/kg,and SOC content was significant positive correlated with available nutrients(available N,P and K)and total nitrogen.Conclusion] This study indicated that the physical and chemical properties of soil,altitude,average annual temperature had a significant influence on the SOC content of Wuyi Mountains.
