Abstract： Taking a solid waste disposalarea in an industrial park asan example， this paper systematicall analyzes theenvironmental impactsofincineration，landfillandstockpilingonsoil.Significantchanges insoilphysicochemical properties were observed across alldisposal zones： the incinerationarea exhibited prominent alkalization characteristics， thelandfillaea showed increasedbulk densityand decreased porositydue tocompaction effects，whilesalt accumulation dominated inthe stockpiling zone.Microbial communityanalysis revealed that distinct disposal methods markedlyaltered soil microbial structureand diversity.Thermophilic bacteria became dominantin incineration areas，anaerobic bacteria proportions increased in landfll zones，and halotolerant bacteria prevailed in stockpiling areas.Multivariate analysis identified pH value，organic mater content，and heavy metal enrichment as key factors influencing microbial communities. The environmental impacts demonstrated clearcumulative efectsand spatialdifusion paterns，with disposal methods exhibiting diferentiated polution pathways.These findings provide scientific evidence foroptimizing solid waste disposal strategies and implementing risk prevention measures
