%X The research results show that the amount of CO_2 emission from soil tends to keeping pace with the temperature change in Xi'an loess area,however the change of the former is later than that of the latter.The amount changes all the year round,with the highest amount in the summer,then the autumn,and the lowest in the winter.The amount varies under the different conditions of vegetation.Generally speaking,there is a higher amount on the bare ground.The emission of CO_2 is sensitive to the texture and structure of soil.More CO_2 is emitted from loose layers than solid ones.
