摘  要:
从矿区复垦林地土壤的物理性状、蓄水性能及渗透性能和枯落物持水量等方面探讨了复垦矿区复垦植被的涵养水源功能。结果表明:随着复垦年限的增加,与新造地相比,土壤的物理性状都有很大的改善,而且植被对平台土壤的改善效应更明显;平台上土壤饱和蓄水量从大到小依次为刺槐×柠条>刺槐林>草地;斜坡上土壤饱和蓄水量依次为草地>刺槐林>柠条林。枯落物的持水量依次为草本>刺槐>油松。因此,乔灌草配置,针阔叶林混交,增加物种多样性,才能有效地改善土壤的保水蓄水能力,特别在复垦初期。

摘  要:
Water-source conservation function of vegetation soil was discussed in reclamation mine from the sides of soil physical properties,water holding performance,infiltration capability and litter layer holding-water capacity.The results indicated that,soil physical properties had been improved compared with newly-construsted land with the increase of reclamation years,and on the platform the vegetation effect on soil is more obvious;On the platform,the order of saturated soil water holding performance was: Robinia pesudoacacia×Caragana korshinskii>Robinia pesudoacacia>herb;on the slope,the order of that was: herb>Robinia pesudoacacia>Caragana korshinski.The order of litter layer holding-water capacity was: herb>Robinia pesudoacacia>Pinus tabulaeformis.Therefore,allocation of arbor,shrub and herb,mixture of coniferous forest broad leaved forest,increasing species diversity,that will effectively improve the soil water-storage capacity,especially in the early reclamation.
