图1. 西南地区不同灌木植物盖度草地群落的植被碳库。图中I、II、III分别代表无灌木植物草地群落、低灌木植物盖度草地群落和高灌木植物盖度草地群落, 数值为平均值±标准误差(I, II, n = 18; III, n = 5)。不同小写字母表示不同灌丛草地间差异显著(p < 0.05)。
Fig. 1. Vegetation carbon pool of vegetation in grassland community with different shrub coverage in southwestern China. I, II, and III are the three different shrub coverage levels of the grassland community. I, II, and III represent no shrub grassland, low shrub coverage grassland, and high shrub coverage grassland, respectively. The data are the mean ± SE (I, II, n = 18; III, n = 5). Different lowercase letters indicate significant differences among sites with different shrub coverage of grassland levels (p < 0.05).
