Abstract: In order to understand the influence of human activities on urban soil,in this study,the soil of different depth was collected from the tree pool,roadside green space and some parks in 8 Districts of Shenyang City,and the physical and chemical properties were analyzed.The results showed that the pH of Shenyang soil was neutral and alkaline,the soil hardening degree was high,the content of organic matter was low,the content of salt was high,the content of available nitrogen and available potassium was moderate,and the content of available phosphorus was very low.The soil pH,available potassium content and electrical conductivity in Heping District were low;the indexes of Dadong District and Shenbei District were higher;the soil electrical conductivity in Huanggu District was low;the content of soil available potassium and organic matter in Shenhe District and Hunnan district were low;the contents of soil available phosphorus and nitrogen in Tiexi District and Yuhong District were lower.The soil indexes of street tree pool,lane and roadside green space were similar,but the indexes of park green space were quite different from them.In conclusion,human activities increased the compactness and hardening degree of urban soil,resulting in the decrease of urban soil permeability;at the same time,the degree of soil salinity was increased,which endangered the growth of urban trees.
