The objective of this research is to estimate carbon fixation of five dominate aquatic plants in Sinhai second phase artificial wetland in New Taipei City. Concering the analysis method, we used image based event identification and on site stratified random sampling to calculate area and density of aquatic plants in artificial wetland, and used high temperature combustion method to estimate organic matter content in aquatic plants. The results showed that carbon fixation of five dominate aquatic plants in Sinhai second phase artificial wetland are: Phragmites communis 501.7 gC m-2yr-1, Typhaangustata 135.6 gC m-2yr-1, Ipomoea reptans 82.3 gC m-2yr-1, Brachiaria mutica 26.8 gC m-2yr-1, Colocasia esculenta 22.2 gC m-2yr-1, Ludwigia x taiwanensis Peng 17.5 gC m-2yr-1. Also, we found that aquatic plants carbon fixation are positive relative with leaf area index (LAI) and leaf area. Totally, carbon fixation of five dominate aquatic plants in Sinhai second phase artificial wetland is 211.0 gC m-2yr-1. By means of image based event identification,We obtained the area of aquatic plants in Sinhai second phase artificial wetland is 35,652 m2, and that we can estimate the carbon fixation of aquatic plants in Sinhai second phase artificial wetland is 7.5 ton yr-1.
