土壤组成<br />
(Soil Components)<br />
4.1.1 土壤化学组成 (Chemical components of soil)<br />
Fig. 4.1 structure of solid, liquid<br />
and gas phases in soil<br />
Soil:multiphase system (solid, liquid, gas)<br />
– lithogenic,biogenic,atmogenic and<br />
hydrogenic components<br />
Solid phase in soil:soil minerals (90%,<br />
including primary and secondary<br />
minerals), organic matters(1%-10%)<br />
and organism<br />
Liquid phase in soil:water and its<br />
solutes<br />
Gas phase in soil:between the matters<br />
in different phases exist holes and<br />
gaps (taking up 35% of the whole<br />
volume of soil) where are filled with air<br />
The ratio of matters in three phases in<br />
soil: mainly in solid phase, the relative<br />
amount of matters in other two phases<br />
depends on the conditions.
