ABSTRACT
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
