Soil respiration rates and its relation with environmental factors in Horqin Sand Land
|
Abstract:
Soil respiration impacts carbon sequestration rates and atmospheric carbon dioxide levels.Daily dynamics and seasonal dynamics in soil respiration rate in three types of fixed,semi-fixed and mobile sand land were measured in 2005 to understand soil respiration properties and its relation with environmental factors in land desertification processes of Horqin Sand Land.The results showed that(1) daily fluctuations in soil respiration presented a single peak curve during spring and autumn and a double peak cur...
