| Abstract: | In order to better understand the spatial distribution characteristics of soil nitrogen in the village of urban agricultural region, surface soil samples were collected and analyzed from the peach orchard in Orchard Village, Nanhui, Shanghai. Traditional statistics and the ordinary Kriging method of geo-statistics were applied to study the spatial distribution of soil nitrogen (TN, NO3--N and NH4+-N) within a depth of 0~20 cm. The results showed that the content of NH4+-N in the soil varies greater than that of NO3--N and TN, and the variation degrees of TN and NH4+-N are higher than that of NO3--N. The linear variogram models can be used to describe the variation of TN, NO3--N and NH4+-N contents, and the spatial correlation of them is moderately interdependent extended to about 740 m, 741 m and 739 m, respectively. The spatial distribution of NO3--N and NH4+-N is patchy, and their contents in the soil close to the village are high; while that of TN is punctate, and the content in the soil of the east is higher than that in other parts. |
