Site soil pollution investigation and assessment is an important part of mastering soil environmental quality,and has guiding significance for subsequent site development and utilization.Through the development of the investigation work,we can clearly divide the contaminated site and the pollution-free site,and then implement the classification and use management.For unpolluted land,it is necessary to strengthen the protection of unpolluted soil in the subsequent development and utilization,and strictly control the pollution of new soil.For contaminated sites,it is necessary to understand in detail the source,pollution factors,pollution ways,and the degree of harm to human health and ecological environment of the site,conduct a comprehensive assessment of the soil pollution situation of the site,and implement risk control or soil remediation in combination with site planning,so as to ultimately promote the safe,effective and sustainable utilization of soil resources.This paper mainly analyzes the main points of soil pollution investigation and assessment in the site,in order to provide reference for the relevant staff.
