Abstract
Compared control forest and prescribed burning forest of six slope of humus layer thickness, loads and organic carbon storage, and these soil levels organic carbon content and carbon storage in Pinus Kesiya, and confirmed to be suitable for carrying out prescribed burning. The experimental data showed that prescribed burning before and after, humus layer thickness of FS and GS are highly statistically significant (P<0.01), others were statistically significant (P<0.05). Loads and organic carbon storage of FS are highly statistically significant (P<0.01), GS, SS, AS and DS are statistically significant (P<0.05). Soil organic carbon content of FS, GS and DS on 0-60cm level are highly statistically significant (P<0.01), others slopes are statistically significant (P<0.05), FS and GS on 20-40cm are highly statistically significant (P<0.01), BS, AS and DS are statistically significant (P<0.05), lat slope and GS on 40-60cm are highly statistically significant (P<0.01), BS is statistically significant (P<0.05). Soil organic carbon storage of SS on 0-20cm is statistically significant (P<0.05), others are highly statistically significant (P<0.01), FS, GS and DS on 20-40cm are highly statistically significant (P<0.01), BS and AS are statistically significant (P<0.05), FS on 40-60cm is highly statistically significant (P<0.01), GS, BS and DS are statistically significant (P<0.05). Prescribed burning can decrease loads in forest, and carbon sequestration in different slope is different, preferred to FS to prescribed burning, next considering GS and BS, those can gain better efficiency, prescribed burning could not be carried out in SS, AS and DS.
