图2. 氮添加处理(圆圈)、增雨处理(正方形)及同时增氮增雨处理(菱形)对地上生物量(AGB)(A)、地下生物量(BGB)(B)、总生物量(TB)(C)及地上地下生物量比(AGB/BGB)(D)的影响(平均值± 95%CI)。图中数字代表独立研究数量。
Fig. 2. Effects of N addition (in circle), precipitation increasing (in square) and N addition plus precipitation increasing (in rhombus) on aboveground biomass (AGB)(A), belowground biomass (BGB)(B), total biomass (TB)(C) and the ratio of aboveground biomass to belowground biomass (AGB/BGB)(D) (mean ± 95%CI). Numbers in the parentheses represent study number.
