[Seasonal fluctuation of plant biomass in land remained bare in Hailun experimental station].
Analysis of the above- and under-ground biomass of the land remained bare for seven years and twenty years and the farmland in Hailun experimental station showed that total biomass increased over the bare period. There was no significant difference in above-ground biomass between bare lands, while the root biomass showed obvious difference, indicating that total biomass was differed mainly from root biomass between bare lands. With longer bare period, the ecosystem had the stronger resistance to environmental stress and the more stability. Meanwhile, its root biomass turnover value was small, which suggesting the higher ability to supply nutrient and energy stably.
