森林生态系统土壤呼吸研究进展

森林土壤碳是全球碳库的重要组成部分,在全球碳循环方面发挥着重要作用。土壤呼吸是当前碳循环研究领域中的一个热点问题,而且目前土壤呼吸已经成为陆地生态系统中向大气释放CO2最大的源。把土壤呼吸量与植物群落生长之间的关系进行分析比较,是理解森林生态系统碳素平衡的核心。在综合介绍国内外有关土壤呼吸的各种测定方法的基础上,对国内外有关森林土壤呼吸的已有研究成果进行了述评,指出了森林土壤呼吸研究工作今后的努力方向。

A Review of Soil Respiration in Forest Ecosystem

Soil carbon in forest ecosystem is the vital component of the global carbon reservoir and it plays an important role in global carbon cycle.Soil respiration is a hot topic in the area of carbon cycle research.It has become the largest source that terrestrial ecosystems release CO_2 to atmosphere.It is the core to understand the problem of carbon balance in forest ecosystem by analysis the relationship between amount of soil respiration and growth of plant communities.Based on the introduction of methods of soil respiration measurement,achievements on soil respiration have been discussed and the future researches on soil respiration in forest ecosystems were put forward.
