草地生态系统固碳能力研究进展

摘要：温室气体大部分是由于大量使用化石燃料致使空气中二氧化碳浓度增多而产生的。经研究表面，陆上生态系统中的绿色植物利用自身的光合作用可以把二氧化碳你转化成碳水化合物，然后采用有机碳的形式是其固存在植物或土壤中，这就是生态系统的固碳能力。现阶段人类为了解决气候的变化问题，对生态系统的研究越来越重要。在各种生态系统的固碳能力研究中，人们发现利用陆地生态系统对二氧化碳的吸收和固存能力是各种生态系统中较为安全和有效的方法。所以，人们对陆地生态系统固碳能力的研究是研究的主要方面。草地作为世界上植被类型分布最广的陆地生态系统，不仅保障着生态安全，还具有丰富的固碳能力。但是很长一段时间人们都只看到了草地的畜牧能力，对其的固碳能力研究不够。

Abstract: most of the greenhouse gases is due to the extensive use of fossil fuels causes an increase in carbon dioxide concentration in the air. Studies the surface, the land ecological system of green plants use their photosynthesis to convert carbon dioxide you to carbohydrates, and then the form of organic carbon is its solid existing plants or soil, that is the ecosystem carbon sequestration ability. Human at present stage in order to solve the problem of climate change, the study of ecosystem is more and more important. In the study of various carbon sequestration capacity of ecosystem, it was found that use of terrestrial ecosystem to absorb carbon dioxide and sequestration ability is relatively safe and effective method in various ecosystems. People, therefore, the research of terrestrial ecosystem carbon sequestration ability is the main research aspects. Grassland as the distribution of vegetation types in the world's most widely terrestrial ecosystem, not only guarantee the ecological security, but also has rich carbon sequestration ability. But for a long time people can only see the grassland animal husbandry ability, the ability of carbon sequestration enough.
