应高度重视大型植物过量生长型的湖泊富营养化问题

PAY MORE ATTENTION TO LAKES EUTROPHICATION OF MACROPHYTA OVERGROWING TYPE

由于营养物的增加和积累,水体的主要生物相应为浮游植物和大型水生植物,表现为浮游植物疯长(藻型)和大型水生植物的过量生长(草型)。草藻混合型应视为过渡型。草型富营养化湖泊多发生在浅水湖泊(水深<4m),我国大部分湖泊水域均处在浅水区域,且湖泊水体营养物含量多数已大大超过富营养化控制警戒线。因此,在研究和控制湖泊富营养化问题时,更应高度重视草型富营养化湖泊。本文将以内蒙古乌梁素海为例,说明草型富营养化湖泊发展的危害和治理控制的重要性和必要性。

Due to the increase and accumulation of the nutrient content,the main vegetation of water body is floating vegetation and macrophyta,which occurs floating vegetation growing fast(alga type) and macrophyta overgrowing(grass type).Combination type of grass and alga was taken granted as transition type.Grass type eutrophication takes place in shallow lakes(water depth less than 4m).Plenty of lakes in China are shallow lakes,and nutrient content of the water body have already extended alertness control values in most of them.So grass type eutrophication lakes should be paid more attention as analysis and control.This article will account for the important and necessity of managing and controlling grass type eutrophication lakes.
