Abstract:

This paper studied changes in soil organic carbon (SOC) content of different soil layers under strip thinning type Ⅰ (reserve 2 lines cut 2 line) and type Ⅱ (reserve 3 lines cut 3 line) of Larix olgensis plantations. The results showed that in five years after strip thinning (conducted in fall 2005), SOC content in 0-20 cm soil layer significantly increased compared with 2005 (P <0.05). Increase in SOC content of each age group after strip thinning in compared with CK was: half-mature forest > young forest > near-mature forest. SOC content decreased with increasing soil depth, SOC content at the same soil layer was as follows: type Ⅱ > type Ⅰ> control plot.

Key words: Larix olgensis plantation, soil organic carbon, strip thinning, mountainous area of east Liaoning Province
