Soil respiration is a key process in the carbon cycle, and researchers studied how warming affects it at XiaoPo Lake. They used a special system to measure soil respiration in different conditions. The results showed that higher temperatures increased soil respiration, with more activity during the day and month. Warming boosted soil respiration and reduced the impact of rainfall on it. The relationship between soil respiration and temperature followed a clear pattern, and warming made soil respiration more sensitive to temperature changes. Soil moisture also influenced soil respiration, especially when there was enough rain.
