图5. 2013-2014年生长季不同增水处理下的净生态系统碳交换(NEE) (A, B)、生态系统呼吸(ER) (C, D)以及总生态系统生产力(GEP) (E, F), (平均值±标准误差)。相同的字母代表不同处理之间最小显著差异(LSD)法多重比较结果差异不显著(p > 0.05), 不同字母表示处理间差异显著(p < 0.05)。
Fig. 5. Net ecosystem carbon exchange (NEE) (A, B), ecosystem respiration (ER) (C, D) and gross ecosystem production (GEP) (E, F) under different water addition treatments in the growing seasons of 2013 and 2014 (mean ± SE). Same letters indicate a non-significant difference (p > 0.05) according to the least significant difference (LSD) test, and different letters indicate significant differences (p < 0.05) among treatments.
