Using Amphibians Biological Point of View to Design the Water Bank of Ecosystem Restoration
With the hilly areas being developed in recent years, there are often concrete constructions by creeks in order to protect the safety of locals and tourists, however, the effect of concrete on the environment and the mobility of certain species are still unknown. The process of building concrete banks on rivers due to human development has become a serious problem in Taiwan of China; most ecosystems used by amphibians are located in lakes and stream banks, yet no related design solutions have been put forth in Taiwan. For this research, we selected eight species of Taiwanese amphibians and discussed their climbing abilities in an effort to better lakes and river banks designs. We evaluated their motility on five appropriate bank degree of slope, and identified the relation between an amphibians abilities and the surface substrates of the banks, under humidity and temperature alterations, to simulate changes across the four seasons. The results showed that, a case study of the climbing ability of Hynobius on moss with a gradient of 15° can be 1.35±0.13 (×10-2N/g); and it remains 0.46±0.15(×10-2N/g) even on a gradient of 75°. When the gradient is 45°, its climbing ability on moss is 1.74, 1.54, 1.40, and 1.17 times of that on clay, cobblestone, wood, and concrete, respectively, therefore, moss is a good material for bank slope of high mountain bank area designs. This research adopted multiple combinations of bank materials and degree of slope, which can serve as reference for technicians involved in future ecological engineering designs of banks.
