摘要
Multivariate statistical techniques were used to analyse a ten-year water quality dataset. Monthly water samples were collected from 15 river mouths during 2002-2011 and analysed for spatio-temporal variation. The results indicated that water quality at Bandon Bay varied spatially and temporally during the past ten years. Four pollution factors were identified: (1) nutrient, (2) organic matter, (3) salinity and buffering and (4) erosion factors. Discriminant analysis on spatial variables identified only four parameters - i.e. water depth, alkalinity, salinity, and temperature - to discriminate between 15 river mouths. Salinity was the only parameter that discriminated between seasons.
