摘　　要：在已实施生态修复工程7-10年项目区中,选取薄土层阳坡、薄土层阴坡、厚土层阳坡和厚土层阴坡实施不同措施的样地24块,测定其生物多样性并预测各样地演替趋势。结果表明厚土层样地物种多样性优于薄土层样地,阴坡样地物种多样性优于阳坡样地;立地条件、生态修复措施和种源等因素共同决定了各样地乔木演替趋势,封造结合是迅速提高河北山地植被多样性的有效手段。In the project area where ecological restoration projects have been implemented for 7-10 years,24 sample plots with different measures were selected,including sunny slopes with thin soil layers,shady slopes with thin soil layers,sunny slopes with thick soil layers,and shady slopes with thick soil layers.Their biodiversity was measured and the succession trends of each plot were predicted.The results showed that the species diversity of the thick soil plot was significantly better than that of the thin soil plot,and the species diversity of the shady slope plot was better than that of the sunny slope plot.Factors such as site conditions,ecological restoration measures,and seed sources collectively determine the succession trend of trees in various fields.The combination of sealing and cultivation is an effective means to rapidly improve the diversity of vegetation in Hebei mountainous areas.
