Abstract
Water quality data, including dissolved oxygen, BOD, suspended particle, ammonia nitrogen and turbidity, were collected from Taiwan EPA river water quality monitoring program during past 20 years. Land use data in both the Tou-Chin Shi watershed and the Lau-Jag Shi watershed were also identified and classified from SPOT images from two different years (1990 and 1999) and their relationship with water qualities were analyzed. The results showed barren and agriculture land use were two major land use categories which affected water quality. The seasonal trends of river water quality parameters were observed in the Lau-Jag Shi and the
Tou-Chin Shi. The trend of turbidity in both rivers were increased. On the other hand, the trend of ammonia nitrogen level was decreased in the Tou-Chin Shi but increased in the Nan-Kan Shi. In addition, there were also some changes in the trends of water qualities of the Nan-Kan Shi.
