摘要

石門水庫為一具有農業灌溉、水力發電、防洪、公共給水、觀光休閒等之多功能水庫。然而因集水區之產業活動，如農業施肥、家庭污水、遊憩活動、畜牧及養殖業，造成許多污染物排入水庫之水體內。為著眼於石門水庫之永續利用，及下游數百萬居民之飲用水安全，石門水庫上游河川區及水庫水體之水質改善工作，實為刻不容緩之要務。本文以理論及數值模式、配合現地調查及水質採樣，對於不同入流量下污染物於石門集水區上游三民溪河道中之削減機制及其擴散範圍加以評估。

Field studies and numerical modelling of water quality in Sanmin river, upstream of Shihmen Reservoir I are investigated herein. Water samplings were performed at different locations in the stream reach, and those data are used to obtain the K_1, K_2, K_3 parameters. QUAl2E model is then employed to simulate the change of water quality at different flow conditions in conjunction with those parameters obtained by field studies. The simulated results are reasonable in comparison with the field data. More research is required to explore the mechanism of the biofilm and sediment oxygen demand on the channel bed.
