寡营养 - 百度百科
网页寡营养(oligotrophic)指水体营养物质缺乏且含有种类较多而数量较少的水生生物的水体，这种水体的特征是透明度高。 上层水体中氧的浓度高，底部堆积物通常呈浅褐色并仅含有少量的有机物。
Oligotroph - Wikipedia
网页Oligotrophs are characterized by slow growth, low rates of metabolism, and generally low population density. Oligotrophic environments are those that offer little to sustain life. These environments include deep oceanic sediments, caves, glacial and polar ice, deep subsurface soil, aquifers, ocean waters, and leached soils.
