摘要
大气二氧化碳含量正在以每年0.4％的速度增加,对森林产生越来越明显的影响,对未来林业提出七个方面的挑战:温度变化、水的变化、气候变化、虫害和火灾变化、新基因的需要、造林与经营、加速研究进程,对此应尽快作出估价。
Carbon dioxide in atmosphere is increasing annually at 0. 4 % and makes more obvious effects on forest. This challenges to future forest in the following 7 aspects; temperature change, water change, climate change, new gene requirement, forest industry and business operation and quickening of study course.
