在我们的生活中偶尔会看到一些长满水草的小池塘,在报纸、电视等媒体上有时也会看到关于“湖泊水华现象”、“海洋赤潮现象”等报导。这些现象是怎样形成的呢? 我经过查阅资料,了解到了一个我原本陌生的名词——“水体富营养化”,即湖泊、水库等水域的植物营养成分(氮、磷等)不断补给,过量积聚,导致水体营养过剩。 Occasionally we will see small ponds covered with aquatic plants in our lives. Newspapers, televisions, and other media sometimes see reports on “lake blooms” and “red tides in the ocean.” How did these phenomena come into being? After consulting the data, I learned about an unfamiliar term, “eutrophication,” ie, the continuous supply of nutrients (nitrogen, phosphorus, etc.) in lakes, reservoirs, and other waters. Accumulation leads to excess nutrients in the water body.
