Abstract

To explain the spatial variation of soil organic carbon in Juniper plantation and the influence of environmental factors on organic carbon,soil samples of 0-80 cm profile depth were sampled.Measured the soil organic carbon and other soil properties,analyzed the vertical distribution of soil organic carbon and the relationship between them.The results showed that soil organic carbon content(36.01%),organic carbon density(34.83%) and available nitrogen content(47.06%) in the 0-20cm soil layer were all relatively large.Soil organic carbon content was significantly positively correlated with soil organic carbon density and soil available nitrogen content.Soil bulk density and soil pH value were negatively correlated with soil organic carbon,while soil total porosity,capillary water holding capacity and capacity and field water holding capacity were positively correlated.The vertical distribution of carbon content in the soil profile of the whole forestland shows a pattern of first steep drop and then gradual decrease.Soil fertility can be improved by changing stand structure and replanting broad-leaved trees.

Key words： Juniper plantation; organic carbon; vertical distribution; influencing factors; soil physical and chemical properties; aggregate
