图2. 科尔沁沙地不同类型封育沙地植物群落特征年际变化(平均值±标准偏差)。FD, 固定沙丘; MD, 流动沙丘; SG, 沙质草地。C, Simpson指数; H, Shannon-Wiener指数; k, 线性回归方程斜率; p, 显著性水平(p < 0.05变化趋势明显)。图中仅列出了置信水平较高的k, R2和p值。
Fig. 2. Interannual changes of plant community features in different enclosure types of sandy lands in the Horqin Sandy Land (mean ± SD). FD, fixed dune; MD, mobile dune; SG, sandy grassland. C, Simpson index; H, Shannon-Wiener index; k, regression line slope; p, statistical significance (p < 0.05 indicates the change trend is significant). Only the k, R2 and p values with higher confidence levels are listed in the figure.
