图3. 秦岭土壤酶活性及总体酶活性沿海拔变化特征(平均值±标准误差)。不同小写字母表示不同海拔高度间差异显著(p < 0.05)。AKP, 碱性磷酸酶; CBH, 纤维二糖水解酶; NAG, β-N-乙酰氨基葡萄糖苷酶; βG, β-葡萄糖苷酶; βX, 木糖苷酶; TEI, 土壤总体酶活性。
Fig. 3. Altitudinal variation of soil enzyme activities and the total enzyme activity index in the Qinling Mountain (mean ± SE). Different lowercase letters within the same column mean significant differences among different altitudes (p < 0.05). AKP, alkaline phosphatase; CBH, cellobiohydrolase; NAG, β-1,4-N-acetylglucosaminidase; βG, β-1,4-glucosidase; βX, β-1,4-xylosidase; TEI, total enzyme activity index.
