Abstract:Duetofactorssuchasmining,smeltingandtailings storage,typical non-ferrousmetal miningareashavehigh stabilityandstrongdifusionof polutionsources,andphytoremediationofheavymetalcontaminatedsoilfacesmultiple challenges.Firstly,theexcesivecontentofheavymetalsinhibitstheeffctivenessofphytoremediation;secondly,the scarcityofsuitableplantsconstrains theabilitytoalocateresources;thirdly,theweakrhizosphereecologyaffects the stabilityoftherestorationsystem;andfourthly,poortechnicaladaptabilitylimitsthecontinuousprogressofrestoration. Based onthe characteristics of soil heavy metal pollution in typical non-ferrous metal mining areas,thedilemma of phytoremediationof heavymetalcontaminatedsoil isanalyzed,and thejointregulationmechanismofphytoremediation is explored,thusprovidingtheoreticalsupportforachievingsoilremediationinminingareas.Overall,itiscesryto constructananti pollution plantcommunitytocope with heavymetal pollution stress;optimize plant resource allcation to match soilconditions indiferentminingareas;strengthenthelinkageofrhizosphereecologytoachievethecollborative restorationofsoilmicroecology;establishasound zoningregulationsystem toensuretheefectivenessofsoilremediationin mining areas.
