- •
We examine C and N distribution along soil profiles of two semiarid forests.
- •
Organic C and N contents are higher in surface layers and remain steady under 1 m.
- •
Inorganic C content is substantial in the loess and relatively stable along profiles.
- •
In this region the soil layer of 1–2 m still stores great amounts of C and N.
- •
Natural oak forest has advantage over black locust plantation in C and N accumulation.
