图5. 2014-2016年不同载畜率处理下生态系统总初级生产力(GEP)、生态系统呼吸(ER)对生态系统净碳交换(NEE)的贡献。CK, 对照; LG, 轻度放牧; HG, 重度放牧。图中每一个数据点为当日观测的每个载畜率处理的每个重复的值。
Fig. 5. Relationship between gross primary productivity (GEP) and net ecosystem carbon exchange (NEE) (left panel) and ecosystem respiration (ER) and net ecosystem carbon exchange (NEE) (right panel) in plots with different stocking rates from 2014 to 2016. CK, no grazing control; LG, lightly grazing; HG, heavily grazing. Each data point in the graph is the value of each replicate to each stocking rate observed during the day.
