摘要

摘要: 底栖海藻是海洋生态系统中重要的初级生产力，开展其固碳和储碳机制研究，有利于提高对我国海域海洋固碳和储碳潜力的认识。本文基于海区条件的模拟，开展了大连海域潮间带优势海藻的日固碳量、日呼吸量和日有机碳释放量的测定，结合海区生物量的调查，阐述了3个海藻床潮间带海藻固碳和储碳的季节变化规律。结果显示：在海藻固碳能力方面，绿藻类的固碳能力最强，褐藻类次之，红藻类最低。大连海域潮间带海藻的固碳量、储碳量和有机碳释放量在12月至5月处于较高水平，6月至11月较低，平均每个海藻床潮间带区域年固碳量和年有机碳释放量分别为1.72×10⁵ g/a和2.1×10⁴ g/a。潮间带海藻月固碳量是储碳量的1.7倍。

Abstract: To better understand the potential of carbon fixation in China Sea, it is necessary to conduct the researches on the mechanism of carbon fixed and stored by benthic seaweeds, the important primary productivities in marine ecosystems. In this paper, some dominant seaweeds from intertidal zones in Dalian were measured on the daily fixed and respired carbon, and daily release of organic carbon. Furthermore, seasonal variation of carbon fixed and stored by intertidal seaweeds from three seaweed beds in Dalian were elucidated, combined with the measurements of the biomass. The results showed that green algae had the strongest capacity in carbon fixation, followed by brown algae and red algae. The carbon fixed and stored, and organic carbon released by intertidal seaweeds in Dalian were higher in December-May, and lower in June-November. The annual total carbon fixed, and organic carbon released by intertidal seaweeds of each seaweed bed were 1.72×10⁵ g/a and 2.1×10⁴ g/a respectively. The amount of monthly fixed carbon was 1.7 times that of stored carbon.
