图1. 黔西南不同石漠化程度土壤胞外酶活性(平均值±标准差)。AP, 酸性磷酸酶; BG, β-1, 4-葡萄糖苷酶; BX, β-1, 4-木糖苷酶; CBH, 纤维素二糖水解酶; LAP, 亮氨酸氨基肽酶; NAG, β-1,4-乙酰-葡糖胺糖苷酶。不同小写字母表示同种胞外酶活性在不同石漠化阶段差异性显著(p < 0.05)。
Fig. 1. Soil extracellular enzyme activity at the different degrees of rocky desertification in southwestern Guizhou (mean ± SD). AP, acid phosphatase; BG, β-1,4-glucosidase; BX, β-1,4-xylosidase; CBH, Cellobiohydrolase; LAP, L-leucine aminopeptidase; NAG, β-1,4-N-acetylglucosaminidase. Different lowercase letters indicated that the extracellular enzyme activity in different degrees of rocky desertification were significantly different (p < 0.05).
