orchards, woodlands and natural reserves.
2 Terms
2.1 Soils. it refers to the porous-layer on the surface of earth land, on which green
plants can grow.
2.2 Cation exchange capacity of soils. it refers the absorbed amount of cations on
the negatively charged soil colloid from solution by virtue of electrostatic attraction,
which is expressed by the cmol of entire exchangeable cations in per kilogram dry soil
(calculated in univalent ion).
3 Classification and Standard Levels of Soil Environment
Quality

containing large pollutants and agricultural soils (excluding vegetable
lands) near minerals; the soil quality basically does not cause hazard
and contamination to plants and environment.
3.2 Standard level
Level I - is the limit value of soil environment quality to protect the natural ecology of
areas and maintain natural background.
Level II - is the limit value to safeguard agricultural production and maintain human
health.
Level III - is the critical value of soils to safeguard agriculture-forestry production and
the normal growth of plants.
