- Soil CO flux is crucial to the global carbon cycle, and variations due to soil erosion can impact atmospheric CO levels and soil organic carbon (SOC) stocks.
- A study conducted in Changwu, China, measured soil CO flux, temperature, and moisture over two years, showing significant differences in CO flux between erosion and deposition sites, with deposition sites exhibiting higher emissions and greater temperature sensitivity.
- The research highlights that changes in soil moisture and SOC redistribution due to erosion and deposition are key factors affecting soil CO flux in these environments.
Evaluating the response of soil microbial respiration to extreme precipitation event is significant for a better understanding about the influence of the change of precipitation regime on soil carbon cycling under global warming. A simulated experiment of extreme precipitations was conducted during the rainy season (July-September 2015) in the Changwu State Key Agro-Ecological Station, Shaanxi, China. The treatments consisted of three total precipitations in rainy season (600 mm, 300 mm, and 150 mm) and two precipitation regimes (10 mm, 150 mm; P, P).

The analysis of soil carbon sequestration function changes of growing two plants is important to gain a deep understanding of soil carbon cycle process and its influencing factors of terrestrial ecosystems under the condition of small watershed comprehensive control. The experiment was conducted in the Changwu State Key Agro-Ecological Station, Shanxi, China.

A field experiment was established in a rain-fed spring maize cropland (Zea mays L. ) in the State Key Agro-Ecological Experimental Station in the Loess Plateau in Changwu County, Shaanxi Province, China.

- Evaluating soil respiration variability in apple orchards helps understand the impact of converting cropland to orchards, with a study conducted at the Changwu State Key Agro-Ecological Station between 2011 and 2012.
- Soil respiration was measured at different distances from the tree trunk, showing that it decreased as the distance increased; specifically, it was 20% to 31% higher at 0.5 m compared to 2 m from the trunk.
- The study found that while soil temperature influenced seasonal changes in soil respiration, it couldn't explain spatial variations, suggesting root density plays a significant role and highlighting the importance of distance from the trunk when assessing soil respiration rates.
