摘要：為更好地保護(hù)黑土地，對(duì)呼倫貝爾市典型黑土區(qū)2 238個(gè)土壤樣品的有機(jī)質(zhì)和全氮含量進(jìn)行統(tǒng)計(jì)與線性回歸分析。研究表明，土壤總氮與有機(jī)碳含量呈正相關(guān)，土壤有機(jī)質(zhì)與土壤中總氮的線性回歸關(guān)系存在較大差異。

關(guān)鍵詞：土壤有機(jī)質(zhì)；全氮；相關(guān)性；黑土

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.

Keywords： soil organic matter; total nitrogen; relevance; black soil
