图6 植被氮同位素随海拔高度的变化 图中数据点为相应海拔高度处所有样品 15 N的平均值,垂直线代表#cod#x000b1;1个标准偏差
Fig.6 Variation of plant 15 N with altitude The data points represent the averaged 15 N values of all the plant samples at each elevation, and vertical bars represent 1 standard deviation of 15 N variability within the samples of each site elevation
