1.富营养化是淡水生态系统的主要威胁。沉水水生植物(大型植物)可以通过与浮游植物争夺光线和营养物质来维持富营养化湖泊的清澈水域条件。大型植物和浮游植物之间的相互作用可能导致植物之间的间接促进作用，并在富营养条件下保持较高的大型植物多样性。然而，尽管对这些生态系统有重要的影响，但在富营养化条件下，间接促进作用在促进以大型植物为主的清水状态方面的作用从未被实验证明。
1. Eutrophication is a major threat for freshwater ecosystems. Submerged aquatic plants (macrophytes) can maintain clear water conditions in eutrophic lakes by competing with phytoplankton for light and nutrients. The interactions between macrophytes and phytoplankton may lead to indirect facilitation among plants and the maintenance of high macrophyte diversities in eutrophic conditions. Nonetheless, the role of indirect facilitation in promoting macrophyte‐dominated clear water states under eutrophication has never been demonstrated experimentally despite important implications for these ecosystems.
