图3. 降水量变化对荒漠草原7月份植物种群生物量的影响(平均值±标准误, n = 3)。
不同小写字母表示植物种群生物量在降水量处理间的差异显著(p < 0.05)。W1, 降水量减少50%; W2, 降水量减少30%; W3, 自然降水量; W4, 降水量增加30%; W5, 降水量增加50%。
Fig. 3. Effects of long-term changing precipitation on plant population biomass in July in the studied desert steppe (mean ± SE, n = 3).
Different lowercase letters indicate significant differences in plant population biomass between the precipitation treatments (p < 0.05). W1, 50% reduction in precipitation; W2, 30% reduction in precipitation; W3, natural precipitation; W4, 30% increase in precipitation; W5, 50% increase in precipitation.
