| Summary: | 碩士 === 國立臺灣海洋大學 === 河海工程學系 === 106 === Wetlands are an important environmental resource for the earth. However, wetlands decrease because of population increase, rapid urbanization, and so on. Research and restoration of wetlands have become important. The Qigu Salt Pan in Tainan is the important wetlands in Taiwan. There are many protected birds living here. To create a good environment, it is necessary to analyze the hydrological environment in Qigu.
The purpose of this study was to expect the restoration of Waterbirds in Qitian Salt Pan. Since most of the water depths below 0.3m is suitable for Waterbirds, while the water depths in s Qigu are mostly more than 0.3m. The study used three methods to reduce the depth of water. Method 1 is to fill a platform. Method 2 is to fill a slope and a platform is filled on the right side. Method 3 is to fill a platform on the left side, after a slope, it is a high platform be filled, and the rightmost side is filled a high ground.
This study uses the hydrodynamic simulation to analyze water depth change and the abundance of birds. Choose the best method by using the increasing of the abundance score per unit cubic meter earthwork changes. The analysis results show that Method 1 is better, followed by Method 2, and Method 3 is the worst.
