[Response of Soil Respiration Rates to Soil Temperature and Moisture at Different Soil Depths of Plantation in the Loess-Hilly Region].

It is of great significance to clarify the influence of soil temperature and moisture on soil respiration rate and its characteristics in ecologically fragile regions under the background of climate change for the accurate assessment and prediction of carbon budgets in this region. The average CO concentration and soil temperature and moisture at different soil depths (10, 50, and 100 cm) were measured using a CO analyzer and temperature and moisture sensors. The soil respiration rate was calculated using Fick's first diffusion coefficient method.
