土地利用方式之保护性耕作与二碳化碳自愿减排研究

Study on conservation tillage and voluntary carbon emission reductionin land use patterns

耕地利用是土地利用方式中重要的一种形式,研究表明,采取保护性耕地措施可以有效遏制土壤中产生的二氧化碳。2016年6月,由中国农业科学院开发的保护性耕地项目方法学进入CCER方法学目录,耕地的减排增汇行为便有了交易价值。本文着重介绍国内CCER政策背景及保护性耕作机制原理,通过对2个案例的研究分析得出初步结论,最后对提高项目开发收益给出了建议。

Arable land use is an important form of land use.Research shows that adopting conservation tillage measures can effectively curb soil-generated carbon dioxide.In June 2016,the conservation tillage project methodology developed by the Chinese Academy of Agricultural Sciences was included in the CCER methodology catalog,giving emissions reductions and carbon sinks from arable land transactions value.This paper focuses on introducing the domestic CCER policy background and the principles of conservation tillage mechanisms.Through the study of two cases,preliminary conclusions are drawn,and suggestions are made to improve project development returns.
