摘　　要：工业化以来的人类活动是全球气候变化尤其是全球变暖的关键因素,这已成为世界科学界的共识。为了早日实现"双碳"目标,碳替代、碳减排、碳循环、碳封存将是4个最主要的技术路径。为细化不同技术的碳中和贡献度,针对国际组织Project Drawdown给出的76种具体减碳技术进行了计算,结果表明:碳减排相关技术将发挥最重要的作用;行为改变将比技术进步产生更大的影响;与自然和热能相关技术的减碳潜力占比分别达到45.9%和35.5%。基于自然在碳循环中的重要作用及我国丰富的自然热能资源,提出了源于自然的碳中和热能解决方案,并以利用地下储热为例分析了其优势。Human activities have been the key inducement of global climate change,especially global warming,since industrialization. This has become the consensus of the scientific community in the world. Low-carbon energy,carbon emission reduction,carbon cycle and carbon storage are the four main technical routs for carbon peaking and carbon neutrality. In order to measure the contribution of different technologies to carbon neutrality accurately,76 specific carbon reduction technologies given by the international organization Project Drawdown are analysed. The results show that carbon emission reduction related technologies will play the most important role;change of human behaviour will exert a greater impact than technological progress;the contributions of nature-derived technologies and thermal energy related technologies on carbon emission reduction potential are 45.9% and 35.5%,respectively. Then,based on the important role of nature in carbon cycle and abundant reserves of natural thermal energy resources in China,the concept of "naturederived thermal solutions for carbon neutrality" is proposed,and its advantages are analysed by using underground heat storage as an example.
