Abstract： To better protect black soil， statistical and linear regression analysis was conducted on the soil organic matter and total nitrogen content of 2 238 soil samples from typical black soil areas in Hulunbuir City. Research has shown that there is a positive correlation between total nitrogen and organic carbon content in soil， and there are significant differences in the linear regression relationship between soil organic matter and total nitrogen in soil.
