| Abstract: | The trends of spatial distribution and variability of soil total nitrogen and organic matter were analyzed using ordinary Kriging interpolation metrod in Lanzhou city.The results showed that the content distribution of soil total nitrogen and organic matter of the soil surface had higher spatial variability,and the variation trend is more consistent.The high-value areas are located in the south and central of the Lanzhou.In addition,the soil nitrogen and organic matter has the high correlation. |
| Keywords: | Kriging interpolation Total nitrogen Organic matter Spatial variability Lanzhou city |
