目的喀斯特高原石质荒漠区植被恢复是当前生态学研究的一个重要课题。本研究的目的是确定植被恢复对根际和非根际土壤中微量元素分布和积累的影响。华山松，胡颓子，和木通属。选择在喀斯特高原的草海县，贵州省，中国植被恢复区。土壤取样使用网格法来测量微量元素铁（Fe），锰（Mn），铜（Cu），锌（Zn）的总含量在根际和非根际soil.ResultsThe代表性的地区containingElaeagnus显示最大量的积累在根际的总微量元素和有效微量元素，除了总锌。与其他类型的植被的根际的代表性地区表现出积累的微量元素的研究。所有类型的植被与生物富集的有效微量元素在根际和非根际土壤中，除了有效铜在与Cotoneaster.ConclusionsRepresentative地区containingPinus显示最大程度的生物富集的总和有效的微量元素在根际和非根际土壤。
AimsThe restoration of vegetation in the rocky desertified areas of karst plateaus is a major problem for present-day ecological studies. The aim of this study was to determine the effects of vegetation restoration on the distribution and accumulation of trace elements in rhizosphere and non-rhizosphere soils.MethodsFour representative areas containing the plantsCoriaria nepalensisWall.,Pinus armandiiFranch.,Elaeagnus pungensThunb., andCotoneaster hissaricusPojark. were selected within a vegetation restoration area in the Karst Plateau of Caohai County, Guizhou Province, China. Soils were sampled using a grid method to measure the total contents of the trace elements iron (Fe), manganese (Mn), copper (Cu), and zinc (Zn) in rhizosphere and non-rhizosphere soils.ResultsThe representative area containingElaeagnusdisplayed the greatest amount of accumulation in the rhizosphere of both total and available trace elements, except for total Zn. Representative areas of the rhizosphere with other types of vegetation showed accumulation of only some of the trace elements studied. All types of vegetation were associated with the bioenrichment of available trace elements in both rhizosphere and non-rhizosphere soils, except for available Cu in areas associated withCotoneaster.ConclusionsRepresentative areas containingPinusdisplayed the greatest degree of bioenrichment for both total and available trace elements in both rhizosphere and non-rhizosphere soils.
