| 英文摘要 | The interaction effects between vegetation and soil are highly significant for vegetation restoration and reconstruction during the succession of abandoned farmland. We chose four kinds of abandoned farmland in the Loess Plateau (1, 6, 12, and 22 yr) to investigate species richness and aboveground biomass. We also determined soil bulk density, pH value, soil organic matter and soil total nitrogen in the 0-60 cm layer. We analyzed species variation processes and trends in aboveground biomass, soil organic matter and soil total nitrogen, as well as the interaction effect between vegetation and soil during the succession stages. Species richness showed an increasing-decreasing-increasing trend and soil bulk density showed a decreasing trend at first, then tended to stabilize during the succession stages. Soil organic matter and soil total nitrogen were significantly different in the soil layers of the 4 kinds of abandoned farmland, and they showed obvious gathering effects at the soil surface. Abandonment time was negatively correlated with soil organic matter and soil total nitrogen. Soil organic matter and soil total nitrogen indicated obvious time effects during the succession stages. Aboveground biomass was significantly correlated with abandonment time, soil organic matter and soil total nitrogen. The results showed that soil organic matter and soil total nitrogen have negative effects on aboveground biomass and that abandonment time has positive effects on aboveground biomass during the succession of abandoned farmland. © 2018, Editorial Office of Acta Prataculturae Sinica.
