图3 短期增温和降水减少对沙质草地土壤酶活性的影响(T0表示自然温度;T表示增温;W0、W20、W40、W60分别表示降水减少0、20%、40%、60%。不同大写字母表示相同降水减少条件下增温处理之间的差异显著,小写字母表示相同温度条件下降水减少处理之间的差异显著,P<0.05;*,处理效应显著,P<0.05;**,处理效应极显著,P<0.01;ns,处理效应不显著) |
Fig.3 Effects of short-term warming and precipitation reduction on soil enzyme activities in sandy grassland (T0, natural temperature; T, warming; W0, W20, W40 and W60, precipitation decreased by 0, 20%, 40% and 60%, Different capital letters indicate a significant difference between temperature treatments at the same precipitation conditions, and small letters show a significant differencebetween precipitation reduction treatments at the same temperature conditions, P<0.05) |
