The Impact

Low-quality stands in Greater Higgnan Mountains were transformed by clear-cuttings with different area of forest gaps, then larch were planted after induced transformations. The LI-8150 multi-channel automated soil CO2 flux system was used to measure CO2 flux on soil surface. Changes of different soil respiration rates and influence factors were analyzed after different transformations. The results indicated that the soil respiration rates were all raised after different transformations compared with no interfered control plots. After analyzing different transformations comprehensively, it showed that the soil respiration rate performed a negative correlation with the soil density significantly, while the correlation with soil organic matter and litter weight in little decomposed was positive (p﹤0.05). The largest Q10 with forest gap area of 625 m2 was 3.561. Influenced by soil respiration rate, soil underground with depth of 10cm showed the strongest temperature sensitivity. The smallest Q10 with forest gap area of 900 m2 was 2.312, and temperature sensitivity of soil was the weakest.

Scientific Attention

The respiratory release of carbon dioxide (CO2) from soil is a major yet poorly understood flux in the global carbon cycle. Climatic warming is hypothesized to increase rates of soil respiration, potentially fueling further increases in global temperatures. However, despite considerable scientific attention in recent decades, the overall response of soil respiration to anticipated climatic warming remains unclear. We synthesize the largest global dataset to date of soil respiration, moisture, and temperature measurements, totaling >3,800 observations representing 27 temperature manipulation studies, spanning nine biomes and over 2 decades of warming. Our analysis reveals no significant differences in the temperature sensitivity of soil respiration between control and warmed plots in all biomes, with the exception of deserts and boreal forests. Thus, our data provide limited evidence of acclimation of soil respiration to experimental warming in several major biome types, contrary to the results from multiple single-site studies. Moreover, across all nondesert biomes, respiration rates with and without experimental warming follow a Gaussian response, increasing with soil temperature up to a threshold of ∼25 °C, above which respiration rates decrease with further increases in temperature. This consistent decrease in temperature sensitivity at higher temperatures demonstrates that rising global temperatures may result in regionally variable responses in soil respiration, with colder climates being considerably more responsive to increased ambient temperatures compared with warmer regions. Our analysis adds a unique cross-biome perspective on the temperature response of soil respiration, information critical to improving our mechanistic understanding of how soil carbon dynamics change with climatic warming.
