新南威尔士大学的研究人员在《Nature Climate Change》上发表论文称,植物储存的碳总量自2003年以来增加了大约40亿吨,而其中很大部分来自于中国的植树运动。论文主要作者Liu Yi说,澳大利亚、非洲和南美热带草原的植被因降雨量的增加而出现增长,俄罗斯和前苏联加盟共和国荒废的农地重新变为森林,只有中国的植被增加是源于人为的植树

新南威尔士大学的研究人员在《Nature Climate Change》上发表论文称,植物储存的碳总量自2003年以来增加了大约40亿吨,而其中很大部分来自于中国植树运动。论文主要作者Liu Yi说,澳大利亚、非洲和南美热带草原的植被因降雨量的增加而出现增长,俄罗斯和前苏联加盟共和国荒废的农地重新变为森林,只有中国的植被增加是源于人为的植树。

Liu Yi称,中国植被增长最主要的地区是在北部,很可能与中国的绿色长城计划相关。绿色长城计划前称为三北防护林规划,自1978年以来,中国为了抵御戈壁滩沙漠种植了至少10万平方英里的森林。绿色长城计划在科学界有争议,部分科学家担心人工植树可能弊大于利,会吸掉宝贵的地下水;其他人则质疑树的死亡率,以及人工树对能抗干旱的草和灌木是否有负面影响。科学家认为绿色长城的长期结果是不确定的。
