以福建三明仙人谷山地生态系统为研究对象，沿300 m、400 m、500 m 和600 m 梯度采集土壤样品，分析了各高程中土壤碳氮磷含量和比例特征.结果显示，随海拔增加，土壤碳氮含量呈现减少的趋势，在600 m 高程处最小，而土壤磷没有表现出固定的变化趋势.300~400 m 海拔区域和500~600 m 海拔区域氮磷的限制可能呈现不同的特点，低海拔区域磷更缺乏而高海拔区域氮更缺乏.为全面评价不同海拔梯度下土壤养分状况，还需要结合山地系统中其它生物因子的碳氮磷的比例特征开展进一步的研究.

This paper targets the ecological system of Xianrengu in Sanming and studies the soil carbon (C),nitrogen(N)and phosphorus(P)concentrations and their stoichiometric characteristics. Soil sam-ples are taken from different elevation plots at 300 m,400 m,500 m and 600 m. The results show that concentrations of C and N contents decrease along altitude gradient,with the lowest C and N contents found in 600m elevation plots. The P content,however,does not show a significant variation. But there is a difference in the soil content at different altitude:P is more limited at 300 - 400 m elevation while N be-comes the No. 1 rarity at 500 - 600 m. However,to estimate the soil nutrient condition more comprehen-sively,the CNP characteristics of other organisms in this mountain ecosystem also have to be taken into consideration.
