Neutralizing acidic soils tree growth causes spike nitrogen export
2016/7/4
A legacy of acid rain has acidified forest soils throughout the northeastern US, lowering the growth rate of trees. In an attempt to mitigate this trend, in 1999 scientists added calcium to an experim...

一组包括中国、美国等科学家在内的团队日前进行了一项生态学研究,对除南极洲外的全球树木密度分析显示,地球上树木数量略高于3万亿。该项研究突破了以往遥感技术只能估算出世界森林面积的缺憾,将有助于了解地球的系统动力学以及促进环境管理工作。迄今为止,政策制定者和科学家们都是依靠卫星图像来做出对于世界森林面积的估算的。但是这种遥感技术不能明确给出树木的数目、密度抑或是木材储量,而这几组数据对了解生物过程和生...

欧盟在森林高附加值技术开发上取得重要进展
欧盟 森林 技术开发
2014/11/21
森林工业是欧盟经济的重要组成部分。森林不仅是纸浆与造纸和木材加工工业的重要原料来源,而且一系列重要化合物和珍贵活性物质的重要来源地,是人类共同的资源宝库。然而迄今为止,森林的潜在价值远未得到完全开发,甚至被作为废弃物而丢弃浪费。比如,现如今的通用纸浆加工技术,只有不到50%的原料生物质,被转化为纸浆用于造纸,其余超过一半的原料生物质则成为低价值的副产品,造成资源极大浪费。
