Abstract: The research was selected different ecologicaleconomic restoration modes as the object in Hetian Town Changting Country,and then analyzed the influence of these modes on soil bulk density, pore structure,characteristic and organic carbon distribution of the waterstable aggregates.The results indicated that different ecologicaleconomic restoration modes adoption significantly improved soil density and soil pore status,but the improved effect was limited compared with ecological restoration mode.In without management modes,the content of waterstable aggregates which size less 025mm was 6289%.With the implementation of ecologicaleconomic restoration modes,soil micro aggregates gradually transform to macro aggregate,which size was more than 5mm and 52mm.The order of soil waterstable aggregates stability in different ecologicaleconomic restoration modes from high to low was Myrica rubra mode,Castanea mollissima mode,ecological restoration mode,interplantation Camellia oleifera mode in Pinus massoniana,Camellia oleifera mode and without management mode.For Ecologicaleconomic restoration mode,the shorter it was implemented,the less waterstable aggregates stability,which indicated that implementation duration was an important factor on waterstable aggregates stability.Soil organic carbon was dominated in those waterstable aggregates which size was more than 5mm and 52mm for different ecologicaleconomic restoration modes.Meanwhile,the content of organic carbon in soil aggregate tended to be reducing with the decrease of soil aggregate diameter class.
