[Objective] This study was to analyze the cumulative absorption of nitrogen,phosphorus and organic matter of the aquatic plant( reed and Zizania caduciflora),and evaluate the value of nutrient cycling and climate regulation in Dianchi Lake wetland. [Method]According to the Component Effectiveness Analysis and Carbon Tax Law to evaluate with data,which was collected by investigation from 2012 to2013. [Result] The same trend between the cumulative absorption of nitrogen,phosphorus and the change of dry matter quantity to the aquatic plant,what is the maximum in July,August and the minimum in October,November. Reed is better than Zizania caduciflora in carbon sequestration capacity. The value of nutrient cycling and climate regulation is 0. 278 million yuan and 1. 20 million yuan respectively,amount to1. 48 million yuan. [Conclusion] The aquatic plant plays an important role in nutrient absorption,accumulation,distribution and return cycle in ecosystem of Dianchi Lake wetland.
