湘中丘陵区4个树种人工纯林土壤-微生物-胞外酶C∶N∶P化学计量特征

Shuitu Baochi Xuebao
目的不同树种人工林因养分吸收利用策略的差异，导致土壤碳(C)、氮(N)、磷(P)质量分数及其化学计量比的改变显著影响土壤微生物活性，土壤微生物是否通过调整自身生物量和胞外酶化学计量比适应土壤的变化仍不明确。为探究不同树种人工林对土壤微生物生物量和胞外酶活性的影响，研究土壤-微生物-胞外酶C∶N∶P化学计量比之间的协变性。方法以湘中丘陵区土壤发育、经营历史一致，不同生活型的4个树种[针叶树马尾松(Pinus massoniana)、落叶阔叶树枫香(Liquidaar formosana)、常绿阔叶树木荷 ...

采伐剩余物不同处理方式对杉木林土壤酸解有机碳及土壤微生物群落的影响

Shuitu Baochi Xuebao
目的酸解有机碳是土壤中重要的有机碳组分，其质量分数变化将影响土壤微生物群落组成，为探讨土壤酸解有机碳和微生物群落对森林采伐剩余物不同处理方式的响应。方法对福建三明格氏栲自然保护区杉木成熟林的采伐剩余物进行清除(R)、火烧(RB)和保留(RR)3种处理，在种植杉木3 a后采集不同土层(0~10、10~20 cm)土壤，对土壤酸解有机碳组分(活性组分Ⅰ、Ⅱ及惰性组分)和微生物群落进行研究。结果1) 采伐剩余物处理对0~10 cm土层土壤酸解有机碳组分无显著影响。10~20 cm土层，RR和R处理下活性组分Ⅰ(
