黄土高原水蚀风蚀交错区不同生物结皮类型对土壤有机碳及其转化的影响
Shuitu Baochi Xuebao[目的] 黄土高原水蚀风蚀交错区是典型的脆弱生态系统,该区域生物结皮广泛分布,生物结皮在土壤有机碳积累与转化发挥着关键作用,然而,生物结皮演替及微生物对土壤有机碳转化相关酶类的影响规律尚不明确。[方法] 研究土壤有机碳-微生物-碳转化相关酶在生物结皮不同演替类型的变化规律,并运用SEM模型分析了三者之间的相互关系。[结果] (1)生物结皮演替显著增加土壤有机碳含量和碳转化相关酶活性,且它们在结皮层(0-2 cm)中的含量均显著高于裸沙和2—5 cm土层(p＜0.05);(2)结皮层细菌 ...
