CARBON BIOGEOCHEMICAL CYCLE IN THE WETLAND ECOSYSTEM

Received Date: 20 December 2010

摘要: 碳的动态循环是海岸盐沼湿地的重要组成部分,生物地球化学作用是推动碳循环的主要动力。海岸盐沼湿地土壤中碳的循环形式主要分为外部循环和内部循环两种:外部循环主要是有机碳、无机碳的输入输出,是由生物地球化学作用和机械搬运作用主导的;内部循环主要是有氧矿化作用、无氧矿化作用和碳酸盐的形成和储存。另外,碳的埋藏作用与湿地和海平面变化的长期响应有关。

Abstract: The dynamic cycle of carbon and carbon compounds is an important part of the coastal salt marsh evolution, and biogeochemical process is the main driving force to promote carbon cycle. This paper made a review on the carbon cycle in the coastal salt marsh soil. The carbon cycle is divided into the external and internal cycles in this paper. The external cycle means mainly the organic and inorganic carbon input and output, including the carbon budget in biogeochemical and mechanical processes, whereas the internal cycle includes aerobic and anaerobic mineralization and carbonate formation and storage. The burial of carbon is related to the long-term response to wetland evolution and sea level changes.
