秦皇岛市陆地植被与大气碳平衡研究

Study on Terrestrial Vegetation and Carbon Balance of Atmosphere in Qinhuangdao Are

地球的碳循环已成为全球气候变化的一个热点,陆地植被是地球破循环中的一个重要贮存库。本文在分析秦皇岛市陆地植被状况的基础上,对CO_2排放量和吸收量进行了估算,结果表明,陆地植被吸收CO_2的数量占排放量的79％。结合秦皇岛市的实际,提出有利于大气碳平衡的对策。

Terrestrial carbon cycle is a hotspot of the earth climate changes research, andterrestrial vegetation is an importan storage in terrestrial cycle. Based on the situation ofterrestrial vegetation in Qin huangdao A rea, this paper calculates the CO_2 emission andCO_2 fdixation. The results indicate that the CO_2 fixation by terrestrial vegetationaccounts for 79% of the total. Integrated with actual status of Qinhuangdao, this paperproposes several countermeasures which are helpful to carbon balance.
