Zusammenfassung:The invention discloses an urban roadside green land soil heavy metal pollution assessment method which comprises the following steps: measuring the total amount of heavy metals and the effective state content of the heavy metals in a research area, and carrying out data statistics on the total amount of the heavy metals and the effective state content of the heavy metals to obtain preliminary data of the heavy metals; on the basis of the preliminary heavy metal data in combination with normal distribution test, spatial distribution characteristics of the total heavy metal amount and the effective state content of the heavy metal are obtained, and preliminary heavy metal pollution assessment is obtained on the basis of the spatial distribution characteristics; and based on the preliminary assessment and in combination with the total heavy metal amount and the effective state content of the heavy metal, determining the risk level of heavy metal pollution in the research area, and according to the risk level, c
