See Appendix B for specific identification. 5.2.3 According to GB/T 21010, identify the construction project and the surrounding land use types, and analyze the soil environment that may be affected by the construction project. Sensitive target.6 Evaluation work classification6.1 Classification The work level of soil environmental impact assessment is divided into first, second and third grades. 6.2 Basis for division 6.2.1 Ecological impact 6.2.1.1 The soil environmental sensitivity of the construction project site is classified as sensitive, sensitive and insensitive. The discriminating basis is shown in Table 1; If the project involves two or more sites or regions, the sensitivity should be determined separately; after two or more ecological impacts are generated If the sensitivity is determined by the relative highest level. Table 1 Ecological impact type sensitivity scale Sensitivity Discrimination basis Salinization acidification alkalization sensitive The dryness of the construction project is a>2.5 and the average buried depth of the groundwater level is < a flat terrain of 1.5 m; or a soil with a salt content > 4 g/kg pH ≤ 4.5 pH ≥ 9.0 More sensitive The dryness of the construction project site is >2.5 and the average buried depth of the groundwater level is ≥ 1.5 m, or 1.8 < dryness ≤ 2.5 and the average buried depth of the annual water table < Flat terrain of 1.8 m; dryness of construction project location >2.5 or perennial a plain area with an average depth of groundwater < 1.5 m; or 2 g/kg< soil salt Area of ≤ 4 g/kg 4.5< pH≤5.5 8.5≤pH< 9.0 Not sensitive to other 5.5< pH< 8.5 a refers to the ratio of the average annual surface water evaporation to the precipitation measured by E601, that is, the ratio of steaming. 6.2.1.2 According to the classification of soil environmental impact assessment items identified in 5.2.1 and the classification work of 6.2.1.1 sensitivity degree classification results, etc. Level, see Table 2.
