定义

  • Lakes with brown- or tea-coloured waters, the colour being the result of high concentrations of humic substances and organic acids suspended in the water. Although dystrophic lakes are often considered acidic, and nutrient-poor (oligotrophic), these lakes actually vary greatly in both pH and productivity.
