Abstract:

The five elements of B, Cu, Mn, Zn and Mo in the soil of Jiedong district of Jieyang City in Guangdong Province were studied. Based on the contents and distribution characteristics of these trace elements, the influencing factors of trace element contents in soil were analyzed from four aspects: parent material, land use mode, pH and organic matter content. GIS spatial analysis, SPSS mathematical statistics and correlation analysis were used to analyze the content, spatial distribution characteristics and influencing factors of soil trace elements in Jiedong district. The results show that the average contents of B, Cu and Mn in Jiedong district are 18.0 mg/kg, 14.5 mg/kg and 313 mg/kg, respectively, and the contents are all in a deficient level. The ave-rage content of Zn is 77.3 mg/kg, which is generally at a relatively rich level. The average content of Mo is 1.31 mg/kg, which is abundant. Correlation analysis shows that B, Cu, Mn, Zn and Mo are all affected by the parent material and land use patterns. The contents of B and Mn are the highest in soil derived from siltstone, Cu and Mo are the highest in soil derived from tuff, Zn is the highest in soil derived from Quaternary sediments. The contents of B, Cu are the highest in farmland soil and Mn, Zn and Mo are the highest in construction land. Soil pH has a positive correlation with B, Cu, Mn and Zn (P<0.01). Soil organic matter is positively correlated with B, Cu and Zn (P<0.001) and negatively correlated with Mn.

Key words: Jiedong district, soil, trace element, distribution characteristics, influencing factor
