China’s inventories have reported substantial forest carbon gains using ground-based forest plot measurements, but independent satellite-based support for such inventories is lacking and the contributions from human management and anthropogenic environmental changes (atmospheric CO<sub>2</sub> growth, climate change and nitrogen deposition) are unknown. Here we use remote sensing and vegetation modelling to investigate the changes in woody biomass carbon and their drivers across China from 2001 to 2020. Our results show a forest cover increase of 6.2% (59.2Mha) over this period and a woody biomass carbon sink of 208.6±51.8Tg C yr<sup>-1</sup>, consistent with the national inventories. The conservation of forest and woodland areas made an unexpectedly large contribution (59.2%) to the observed sink, with an additional 29.4% from anthropogenic expansion. Of these management-driven sinks, 53.7% (99.2Tg C yr<sup><span style="font-size: 13.3333px;">-1</span></sup>) is attributed to a direct management effect and the remaining 46.3% to the effects of environmental changes. China’s ecological restoration projects contributed 73.5% of the direct management effect. Our study provides satellite-based evidence to support China’s inventories and underscores the crucial role of human management in the nation’s woody carbon balance.</p> <p> DOI: 10.1038/s41561-024-01569-0</p> <p> Source: <a href="https://www.nature.com/articles/s41561-024-01569-0">https://www.nature.com/articles/s41561-024-01569-0</a></p> </p> <div class="remarks">期刊信息</div> <div class="dd"><div> <strong>Nature Geoscience：</strong>《自然—地球科学》，创刊于2008年。隶属于施普林格·自然出版集团，最新IF：21.531</div> <div> <strong>官方网址：</strong><a href="https://www.nature.com/ngeo/">https://www.nature.com/ngeo/</a></div> <div> <strong>投稿链接：</strong><a href="https://mts-ngs.nature.com/cgi-bin/main.plex">https://mts-ngs.nature.com/cgi-bin/main.plex</a></div> </div> </div> </div> <style> #footer{ background:#890f0e; text-align:center; padding:10px; color:#FFF; font-size:12px;} #footer a{color:#FFF; font-size:12px;} </style> <div id="footer"><a href="http://www.sciencenet.cn/aboutus/" target="_blank">关于我们</a> | <a href="http://www.sciencenet.cn/shengming.aspx" target="_blank">网站声明</a> | <a href="http://www.sciencenet.cn/tiaokuang.aspx" target="_blank">服务条款</a> | <a href="http://www.sciencenet.cn/contact.aspx" target="_blank">联系方式</a> | <a href="http://www.sciencenet.cn/RSS.aspx">RSS</a> | <a href="mailto:jubao@stimes.cn">举报</a> | <a href="https://stimes.sciencenet.cn/">中国科学报社</a> <br> <a href="https://beian.miit.gov.cn" target="_blank" > 京ICP备07017567号-12 </a> 互联网新闻信息服务许可证10120230008 京公网安备 11010802032783<br>Copyright @ 2007-<script type="text/javascript">var Date22 = new Date();var year22 = Date22.getFullYear();document.write(year22);</script> 中国科学报社 All Rights Reserved<br> 地址：北京市海淀区中关村南一条乙三号 邮箱：blog@stimes.cn <br> <span style="display:none"> <script type="text/javascript"> var _bdhmProtocol = (("https:" == document.location.protocol) ?
