增温和降水改变对土壤CO<sub>2</sub>释放影响研究进展
摘要
Global warming is expanding the frequency, scope, duration, and severity of severe drought and heavy rainfall events.Extreme climate events such as high temperatures, droughts, and heavy rainfall have significantly changed the rate and intensity of soil organic carbon mineralization and inorganic carbon release.The release of soil CO 2 , as an important component of the carbon cycle in terrestrial ecosystems, is highly sensitive to climate change.Exploring the relationship and response mechanism between soil CO 2 release and climate change can provide theoretical support for in-depth understanding of soil carbon cycling and source sink mechanisms in the context of global warming.In this paper systematically it analyzes the previous studies on the effects of warming and precipitation changes on soil respiration (Rs) and soil carbonate mineral dissolution, and analyzed the impact of 基金项目： 国家自然科学基金面上项目(No.
