Seasonal and Interannual Variation of Soil Respiration on the Sanjiang Plain Wentlands in Northeast China

Abstract:

Response of soil respiration in temperate wetlands in northeast China was studied from June 2009 to September 2011. Li-Cor 6400 infrared gas analyzer connected with a chamber was used to quantify the soil respiration. Results showed that soil respiration displayed a distinct seasonal pattern, with higher values observed in midsummer and lower values in spring and autumn. Furthermore, soil respiration exhibited a significant inter-annual variation. In addition, soil respiration presented significant positive exponential relationships with soil temperature. Whereas, significant exponential decay relationships between soil respiration rate and soil water content was found. In this ecosystem, soil temperature, soil water content and plant phenology together control soil respiration.
