南京农业大学农学院《Environmental Science & Technology》发表水稻栽培团队“Unexpected parabolic temperature dependency of CH4 emissions from rice paddies”(图)
水稻栽培 低碳排放
2022/3/23
气候变暖日益加剧,而稻田甲烷(CH4)排放对气温升高的响应依旧扑朔迷离即正响应、负响应或无响应都常被报道。南京农业大学丁艳锋教授团队联合国内外优势团队发现稻田CH4排放对气温升高响应的不确定性主要由淹水期背景气温导致,即适中的背景温度下响应强而低温或高温响应弱。增温导致的稻田CH4的增排效应被主流模型严重低估。相关研究成果以“Unexpected parabolic temperature dep...
