黄土丘陵区典型土地利用类型土壤-微生物量及其生态化学计量特征
Shuitu Baochi Xuebao[目的] 为探讨黄土丘陵区“上退下推”典型生态治理模式对土壤-微生物量C、N、P及其生态化学计量比的影响。[方法] 以宁夏黄土丘陵区典型土地利用类型(人工林地、梯田和川道地)为研究对象,研究土壤-微生物量C、N、P含量对土地利用变化的响应,并分析其生态化学计量比、微生物熵(qMBC、qMBN、qMBP)及化学计量不平衡性(C∶Nimb、C∶Pimb、N∶Pimb)之间的关系。[结果] (1)3种典型土地利用类型下,人工林地土壤SOC、C∶P、N∶P高于梯田和川道地,而农耕用地(梯田和川道地 ...

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(
