摘      要：An analysis of the seasonal and vertical distribution of soil nematode communities under three contrasting land uses,i.e.,cropland,abandoned cropland and woodland was conducted in an aquic brown *** results showed that different land-use types affected the spatiotemporal distribution of soil nematodes and their dominant genera,and different dominant genera showed different responses to land *** the abandoned cropland and woodland,most dominant genera were present in the 0–20 cm layers and Chiloplacus was mainly distributed in the 5–30 cm layers,while in the cropland,Pratylenchus exhibited an even distribution from the 0–5 cm to the 40–50 cm *** environmental parameters under different land use could influence soil nematodes;soil porosity,total organic C,total N and the C/N ratio could positively influence the abundance of some dominant *** profiles revealed that environmental stability and the homeostasis in the abandoned cropland and woodland lead to higher levels of community structure,and the soil food web tends to succeed to *** faunal analyses are a useful indicator for interpreting the stress and/or nutrient conditions under different land uses.
