生物碳汇类型的特性研究

Research on the character of the biological carbon sink type

温室气体增加被认为是全球变暖的主要原因,CO2是大气中最重要的温室气体,在对温室效应和全球气候变暖的贡献中,占70%。为应对全球变暖,各国采取多种措施致力于温室气体的减排增汇。减少二氧化碳温室效应,除人工减排增汇外,自然界生态系统的生物碳汇功能起着主导作用。生物碳汇主要类型有森林等陆生植物碳汇、水生高等植物和低等植物碳汇、水生高等动物碳汇等等,各种类型生物碳汇功效不尽相同,各具特性。

Increase in greenhouse gases is considered the main reason for global warming, CO2 is the atmosphere of the most important greenhouse gas, in the greenhouse effect and global warming contributions, accounting for 70%. In response to global warming, eountries have adopted various measures to reduce emissions of greenhouse gases is committed to increasing carbon sink. To reduce carbon dioxide greenhouse effect, in addition to reducing emissions by artificial exchange, the natural ecosystem function of the bio- log!cal carbon sequestration plays a leading role. The main types of biological carbon sinks of forests and other terrestrial plant carbon sequestration, aquatic plants and lower plants carbon sinks, aquatic animals, higher carbon sinks and so on, the effectiveness of various types of biologieal carbon sinks vary each with their own characteristics.
