| Summary: | 碩士 === 高苑科技大學 === 土木工程研究所 === 105 === In recent years, the research of wetlands has played an important role in the process of global climate change due to the long-term sequestration of atmospheric carbon dioxide (CO2). Because of its functionality to absorb or emit carbon dioxide, together with the performance of carbon sequestration, wetlands have the environmental characteristics of high water levels and anaerobic bottom. This study is based on the Chiku Lagoon, Hu-Tou-Pi Reservoir and constructed wetland in Chia-Nan University of Pharmacy & Science to monitor water quality, gross primany production, emission fluxes of CO2, CH4 and N2O, and the soil organic carbon density to analyze carbon sequestration gas flux measurements calculated exchange. The research can respond the international development trends, and develop the technology of wetland carbon management.
This study combines the carbon balance calculation method with the concept of net ecosystem production into the carbon mass balance model. The net primary production of the wetland will be deducted from the net primary production of the wetland. The carbon storage capacity and carbon stock of the wetland can be obtained by estimating the carbon storage capacity and carbon stock.
The results of this study found that the strongest carbon sink capacity about 1,644 g Cm-2 yr-1 for artificial SSF wetland in Chia-Nan University of Pharmacology and Science, and the second strong carbon sink capacity reach 504~727 g Cm-2 yr-1 for mangrove forest in Chiku. Other wetlands show only weak carbon sink, and even some of them are carbon source.
