Abstract:

Through the observation of the determination of the basic physicochemical properties and organic carbon content in 0～20cm and 20～40cm soils of different types of plants within four different levels of pollution areas in Baosteel，the characteristics of soil organic carbon content in city industrial environment were evaluated， in order to achieve reasonable green distribution and enhance the effectiveness of green carbon reduction Results showed as follows （1） Soil organic carbon in industrial area had "accumulation effect" （2） Soil organic carbon content of deciduous broadleaved forest in clean area was high， which proposed to plant more willow （3） Soil organic carbon content of coniferous and broadleaved mixed forest in slightly polluted areas was high， soil organic carbon content in coniferous types was significantly higher than that of coniferous forest and evergreen broadleaved forest， which proposed to plant more cedar plus Yulan type or cedar plus camphor （4） Organic carbon content of evergreen broadleaf forest in moderate polluted area or heavily polluted area was high， which proposed to plant more Loropetalum or Ligustrum lucidum， meantime， heavily polluted area should have diversified types of plants 
