The Impacts of Environmental Changes on Stream Temperature of Taiwan Salmon''s Habitat / 環境變遷對櫻花鉤吻鮭棲地水溫之影響

碩士 / 國立臺灣大學 / 農業工程學研究所 / 89 / Stream temperature is taken as a very important ecological index while investigating ecosystem. The change of stream temperature might influence growth rate and survival of fish and other aquatic organisms, so many researchers have put emphasis on keeping stable stream temperature. This research offers a physical model for predicting the impact of climate change on stream temperature. Stream temperature is simulated by energy balance. Because upstream watershed in Taiwan is surrounded with high mountains, the influence of shade of mountains on solar radiation and long wave radiation is taken into account in this study.
  Temperature and streamflow changes are derived from the predictions of four General Circulation Models (GCMs) and landuse change. Under the concentration of atmospheric carbon dioxide is doubled, the result indicates that it’s a little bit change of stream temperature in August and stream temperature increases 2%~11% in November. Under different landuse condition, the result indicates that base flow decreases and stream temperature increases when the higher development. On the contrary, base flow increases and stream temperature decreases when the lower development.
