Abstract

Abstract:

Aims Our objectives are to compare soil respiration rate and its temperature sensitivity at different land use types and discuss soil respiration response to soil temperature (T_s) and soil water content at different soil depths.
Methods Periodic measurements of soil respiration rates (R_s) were made during August-October 2009 with a LI-8100 portable automated soil CO₂ flux system in three agro-pastoral ecotone land use types: cropland, abandoned cultivated land and grazing enclosure. Soil temperature and soil water content at 0-5, 5-10 and 10-15 cm depths were measured simultaneous adjacent to the soil collar.
Important findings R_s is significantly different among the three land use types and greatest in cropland. R_s exhibited a unimodal curve during 6:00-18:00, with a maximum during 12:00-15:00. R_s decreased with T_s, so R_s was significantly higher in August than in September and October. With the Van’t Hoff model, we concluded there is a positive, exponential relationship between measured T_s and R_s. In addition, temperature sensitivity of soil respiration (Q₁₀), which is derived from the Van’t Hoff model, was largest in cropland. In contrast, R_s was negatively related to soil water content in different soil depths at the sites.

Key words: Q₁₀, soil respiration rate, soil temperature, soil water content
