在未来的数十年里,单环境变化或工业技术进步所引起的影响不可能比大气中二氧化碳含量的增加对森林的影响更为普遍。二氧化碳的增加对整个世界及各地气候的变化是一个关键性的因素,它将直接影响树木的生长发育。因为,二氧化碳含量的增加会影响森林的生态关系和林木的生长条件。本文为对二氧化碳增加效应的科学性与变异性作一评论,并对此而引起的林业七项挑战作一概述。
In the decades to come, the impact of a single environmental change or industrial technological advance can not be more pervasive than the impact of increased levels of carbon dioxide in the atmosphere on forests. The increase of carbon dioxide is a key factor for the climate change in the whole world and all over the world. It will directly affect the growth and development of trees. Because, the increase of carbon dioxide content will affect the ecological relations of forests and tree growth conditions. In this paper, we comment on the scientific and variability of the carbon dioxide increase effect and give an overview of the seven challenges to forestry.
