摘　　要：根据南京市城市土地利用类型,对不同绿地类型土壤进行实地调查和取样,测定土壤的pH值、容重、有机质、全氮、全磷、速效磷、速效钾等土壤肥力指标。结果表明:南京市城市绿地土壤肥力状况整体一般,有机质含量较低,容重偏大,全氮、全磷含量处于偏低水平,但速效养分状况良好。According to the urban land use type and through the field survey and sampling of soil on the different types of green space in Nanjing City,we measured p H,bulk density,organic matter,total N,total P,available P,available K.The results indicated that the Nanjing urban green space soil fertility status overall general,soil organic matter was low,the density was high,N and P were very low,but the available nutrients was in good condition.Based on the results of the study,we put forward some suggestions on soil management of urban green space in Nanjing,in order to provide reference for the rational utilization and improvement of urban soil.
