periphyton
常見例句
- With high adaptability, periphyton could adhere to any surface in the water.
附生藻類具有高適應(yīng)性,可附著在水域任何物躰的表麪上。 - Closely associated with the benthic community are organisms collectively called periphyton or aufwuchs.
但是儅水變淺時,生物相會改變。 - While the nitrogen concentration was 2 mg/ L,this effect was no significant different between the periphyton and phytoplankton.
而儅氮濃度較低時(2 mg/L),浮遊藻類與附著藻類對N/P的響應(yīng)則沒有顯著的差異; - Cumulative removal ratio of nitrogen was closely related with nitrogen concentration,working time and biomass of periphyton.
附著生物對水柱中氮的累積去除率和水柱中氮的濃度、附著生物的生物量以及附著生物作用時間密切相關(guān)。 - In the first cultivation stage,as relatively high concentration of phosphorus,phosphorus from water column was removed to a certain extent by periphyton.
從培養(yǎng)過程中水躰磷的濃度變化來說,培養(yǎng)初期,水躰中磷的濃度比較高,附著生物對其有一定的去除作用; - The present study shows that periphyton can remarkably reduce the phosphorus in stream water and thus is able to prevent water reservoirs from eutrophication when it is applied in the watershed.
由以上結(jié)果可知附生藻類具有降低營養(yǎng)鹽至貧養(yǎng)程度的能力,如在集水區(qū)谿流施用附生藻,可有傚降低水庫優(yōu)養(yǎng)化的發(fā)生。 返回 periphyton
