森林对地气系统碳素循环的影响

Influence of Forest on Circulation of Carbon in the System of Earth and Atomsphere

本文研究了森林对地气系统碳素循环影响的机制和作用,并做了定量估算.结果表明,森林是除海洋外对地气系统碳素循环影响最大的自然因素;与海洋不同,森林可由人们管理和调控;人们通过保护和发展森林资源,扩大森林面积,提高森林生产率,控制采伐和防止毁林,可在一定程度上遏制大气中CO_2浓度增长和温室效应增强,从而对减缓和控制地球变暖将会起到积极作用.

Research was done on the mechenism and effect of forest on the circulation of carbon in the system of earth and atomsphere,and a quantitative estimation was made.The research shows that the forest is another important factor besides the sea which influences the circulation of carbon in the system of earth and atomsphere.unlike the sea,the forest is manageable and controllable by human beings.By means of protecting and developing forest resources,expanding forest areas,raising forest productivity,controlling forest cut and preventing forest damage,the concentration of CO2 in the atomsphere can be stopped from increasing and the greenhouse effect will be weakened which will play a positive role in retarding the process of warming up of the earth.
