Abstract:
The strong alkali soil in Qitai county in the south edge of Junggar basin was selected as the study area，and the effects of different simulated rainfall intensity （light rain,moderate rain,heavy rain）on strong alkaline soil respiration rate were measured and analyzed.The results showed that the light rain process added much more release of soil respiration rate，in the process of rainfall，the soil respiration rate increased 320.69% than background value，and after rainfall the soil respiration rate was still more than background value of 58.82%；in the process of moderate rain，the soil respiration rate reduced as much as 48.27% than background value，but it increased 29.41% after rainfall；the effect of heavy rain was characterized by a rapid soil respiration rate decline with 306.89% and 188.24% below background value respectively in rainfall process and after.The heavy rain contributed strong effect of carbon dioxide absorption.
