碩士 / 中國文化大學 / 生物科技研究所 / 93 / The environmental pollution of north coast of Taiwan has become noticeable recently due to the increasing visitors and activities brought by the ease of travel and increased ecological activities recently. The purpose of this study was to evaluate the water pollution of the north coast of Taiwan via investigating the water quality and aquatic insect profile of the regional rivers with environmental sustainable development as prerequisite. Futhermore, it is our future goal to point out the source of pollution and to deal with the treatment to improve the water quality. This study was conducted from 2003 to 2004, water quality and water insect profile were investigated monthly. Results showed that water quality of Ba-Lein and Lau-Mai river were good with temperature ranging from 13.6℃ to 31.8℃. The dissolved oxygen was greater than 70% saturation throughout the year. Among the water insect distribution, the most found species was zooplankton, and the dragonfly and damselfly were the next. There were 16 families and 22 geniuses of insects found in Ba-Lein and Lau-Mai rivers. The biodiversity index was ranked between 1.4 to 3.5 and increased from down stream to up stream. In conclusion, the water quality of Ba-Lein and Lau-Mai rivers were considered as good quality. There was slight discrepancy between the biotic index (BI) and water quality index (WQI) and might need further investigation.
