| Summary: | 碩士 === 逢甲大學 === 水利工程與資源保育學系 === 107 === Carbon dioxide in the atmosphere can be absorbed by wetlands. Coastal wetlands own the highest carbon fixation efficiency in the carbon sink systems. High carbon sink capacity can improve carbon cycle imbalance and global warming caused by human activity. Siangshan wetland at the western coast of Taiwan is the study region in this article. The daily tidal wash and the anaerobic bottom environment, and the mangrove removal planning over the years are the basis in this research. The purpose of this study was to observe the changes of organic matter in the 0-10 cm and 10-30 cm depths of the soil by stubble. And use non-stubble area as a control group to analysis the Carbon sequestration. The organic matters by long-term observation of the experimental results of the sample area could be further analyzed. And the results can provide a reference for the management, planning and design of subsequent wetland remediation management. The analysis of this experiment uses dry ashing method to measure the organic matters contents. The results showed that the organic matter concentration of plant residues was significantly higher than that of the surrounding soil, and the increase of nutrient sources. Because of the increase in nutrient sources. The chlorophyll alpha content has increased significantly from July 2017 to January 2018. This change proves that the wetland can store the organic matter decomposed by the plant residue in the soil to increase the carbon sink, and the Wetland rehabilitation is effective in the way of stubble.
