摘要

Soil organic carbon (SOC) and soil respiration (SR) were estimated in two different land uses (dry deciduous forest and grass land). The estimated SOC down to 30 cm depth was 36.35 Mg C ha"1and 8.69 Mg C ha'in forest and grass land respectively. On forest and grassland, SOC at 0-10 cm and 10-30 cm were 44.67 Mg C ha'1 and 28.47 Mg C ha"1 and 10.14 Mg C ha'1 and 7.24 Mg C ha"', respectively. On grass land, SOC were 10.14 Mg C ha"1 and 7.24 Mg C ha'1 at the 0-10 cm and 10-30 cm. SOC decreased from topsurface layer to sub surface layer in both land use. Lower bulk density values were in dry deciduous forest (1.46 g cm"3) than grass land (1.61 g cm"3) revealing a significant negative correlation between SOC and BD. The soil respiration rate in the forest was 107.8 C02mg/m2/h but was low in grass land (31.16C02mg/m2/h). Astrong positive correlation existed between SR and SOC values.
