图2 有机种植相比常规种植对节肢动物丰富度(A)、多度(B)、均匀度(C)指数的增加率。图中圆点为效应值, 即有机种植相比常规种植节肢动物多样性指数的相对变化百分率, 误差线为效应值的95%置信区间, 括号内的数值为该效应值的样本量。若效应值的95%置信区间未跨越零轴, 则表示该效应与对照相比差异显著; 若亚组内不同水平的效应值95%置信区间未重叠, 则说明分类水平的差异显著。Qb (组间异质性)和P值用来描述不同水平分类因素多样性指数效应值的统计学差异。

Fig. 2 The relative change of arthropod richness (A), abundance (B), and evenness (C) under organic planting compared with conventional planting. The dots in the figure are the mean effect sizes, which represent the relative change of different diversity index (%) under organic planting compared with conventional planting. The error lines indicate the 95% confidence interval (95% CIs) of the mean effect sizes, and the value in brackets is the sample size. Mean effect sizes were considered to be significantly different from the control if their 95% CIs did not cross the zero axis, and were considered to be significantly different if their 95% CIs did not overlap. Between-group heterogeneity (Qb) and the probability (P) were used to describe statistical differences in the diversity index responses between different levels of the categorized factors.
