| 摘 要： | CO2的增加是导致全球气温增加的主要因素之一。本文针对陆地生态系统是全球的3大碳库之一,分析了碳在森林、草地、湿地以及农田等陆地生态系统中的收支,并重点评价了碳在不同陆地生态系统中的积累部位和积累量;同时详细分析了影响不同陆地生态系统释放碳的因素,最后提出了增加陆地生态系统对CO2截存和减少CO2排放的措施。

| Abstract: | Carbon dioxide enrichment was one of the key factors that increased atmosphere temperature. Carbon cycle in forest ecosystem, meadow ecosystem, wetland ecosystem and field ecosystem was analyzed as terrestrial ecosystem was one of key carbon sinks in the world. The quantity of allocated and accumulated carbon of different terrestrial ecosystem was emphasized. Meanwhile factors resulted in carbon dioxide emission from terrestrial ecosystem was analyzed in detail. At last, measures of carbon dioxide fixation increases and emission reduction from terrestrial ecosystem were put forward. |
