图5. 不同放牧强度下不同处理对内蒙古荒漠草原3年平均土壤呼吸速率的影响(平均值+标准误差)。CK、LG、MG、HG分别表示不放牧、轻牧、中牧和重牧。CKs、N、W、NW分别表示不加水和氮、加氮、加水、加氮加水。不同小写字母表示不同处理间差异显著(p < 0.05)。
Fig. 5. Effects of different grazing intensities on the average soil respiration rate during the three years (2015-2017) under different water and nitrogen treatments in a Nei Mongol desert steppe (mean + SE). CK, LG, MG, HG represent non-grazing, light grazing, moderate grazing and heavy grazing, respectively. CKs, N, W, NW represent no addition of water and nitrogen, addition of nitrogen, addition of water, and combined addition of water and nitrogen, respectively. Different lowercase letters indicate significant difference between treatments in the same year at the 0.05 level.
