1·Carbon fixation was one of the important ecosystem services of wetland.

固碳是湿地生态系统一项重要的服务功能。

2·Carbon fixation in every cover crop treatment is higher than that of winter fallow cropland.

黑麦草的碳蓄积量显著高于紫云英和油菜，各覆盖作物处理碳蓄积量均显著高于冬闲田。

3·The aquatic-living colonies had a higher photosynthetic carbon fixation capacity than the natural colonies.

水生原植体的光合固碳能力比天然原植体高。

4·Photosynthesis contains a complex series of reactions, and carbon fixation is the core reaction of photosynthesis regulation.
