摘要: Understory vegetation plays a vital role in regulating soil carbon (C) and nitrogen (N) characteristics due to differences plant functional traits. Different understory types have been reported following aerial seeding. While seeding is common areas with serious erosion, few studies conducted investigate changes C N cycling as affected by aerially seeded plantations. Here, we studied under two naturally formed (Dicranopteris graminoid) Pinus massoniana Lamb Across the types, organic was significantly correlated all measured variables, including total N, available microbial biomass water-soluble while variables except C. Dicranopteris graminoid differed their effects on process. Except C, other were higher soils graminoids. The levels of consistent litter root quality (C/N) compared Dicranopteris. Changes cycles might be impacted via or quality.
