一项新研究显示，英国森林锁住的导致全球变暖的碳是此前认为的两倍。这项使用激光和三维扫描的研究表明，古树在应对气候变化中起到的作用尤为关键。

 

Professor Kim Calders from Ghent University is laser-scanning what's said to be the UK's most scientifically studied forest: Wytham Wood in Oxfordshire. For their research, he and his colleagues scanned nearly a thousand trees, producing detailed¹ three-dimensional maps from which they could work out the weight of each one.

根特大学的金·考尔德斯教授正在用激光扫描据说是英国被研究最多的森林：牛津郡的威萨姆森林。在他们的研究中，考尔德斯教授及其同事扫描了近一千棵树，绘制了详细的三维地图，从中可计算出每棵树的重量。

 

This revealed that an average patch of UK woodland is heavier than was estimated and therefore contains much more carbon – almost twice as much as previously² thought. The scientists say their findings show the value of established, mature woodland for fighting climate change has been underestimated.

计算得出，英国一块普通林地的重量比估计的要重，因此碳含量更高，几乎是之前估计的两倍。科学家们表示，他们的发现表明，生长已久的成熟林地在对抗气候变化方面的价值被低估了。
