Abstract:
Seven-year-old grapes at the eastern foot of Helan Mountain in Ningxia were used as the research object,and the relationship between total organic carbon,light organic carbon,recombinant organic carbon,high activity,middle activity and low activity organic carbon in soil and some physical and chemical properties of soil were analyzed in soil based on geo-detector,in order to study the relationship between soil organic carbon and its components and soil nutrients in arid and semi-arid areas.The results showed that the content of soil total organic carbon in the eastern foot of Helan Mountain was lower than the average level of China,the average value was (3.93±2.49）g?kg-1,the variation intensity was weak and moderate,and decreased vertically(downward-slightly upward-downward).Interactive detector showed that total potassium and available potassium are the most powerful interaction factors between light group and active organic carbon.Factor detector and Ecological risk detector shows that total nitrogen had a significant effect on the spatial distribution of soil total organic carbon and had the greatest contribution to the spatial distribution of soil total organic carbon,in order to provide a basis for comprehensive understanding of the contribution of soil organic carbon driving factors.
