摘要：

Emissions of carbon dioxide were measured from diverse soils in the surroundings of Malaga (Spain). These measurements were carried out by two methods. A direct method using a static open chamber technique and another indirect method obtained from simultaneously measured Rn-222 Bur and concentration profile measurements of Rn-222 and CO2 in the air of soil. The directly measured CO2 fluxes at investigated sites is slightly higher than CO2 fluxes derived from the indirect method. Carbon dioxide emitted by soils, showed a mean direct flux to the atmosphere of 5 mmol m(-2) h(-1) .
