Water blooms often develop on the surface, preventing the light penetration and oxygen absorption necessary for underwater life.
水体表面常常出现水华，水华妨害水下生物所必需的阳光的透入和氧的吸收。Other elements (e. g. , rare earth elements and heavy metals) seem to play assistant roles for the water-bloom occurrence and development.
其他元素（如稀土元素和重金属元素等）在水华发生、发展中则起辅助作用。When conditions are right, phytoplankton populations can grow explosively, a phenomenon known as a bloom.
一旦条件成熟，浮游植物种群数量会呈爆炸性增长，这一现象被称为水华。Algae-lysing bacteria would be one of controlling methods for microcystis water-bloom.
溶藻细菌有可能作为微囊藻水华控制的方法之一。The phytoplankton bloom is not the only source of color in the scene.
浮游植物水华不是造成图像上多彩景观的唯一原因。So far, the rising sea levels, dying corals and spreading algal blooms are only minor distractions for most people.
迄今为止，对大多数人而言，海平面升高、奄奄一息的珊瑚虫、蔓延的藻花水华只不过是次要的烦恼。Water blooms leading by eutrophication had become a serious problem threatening the safety of drinking water.
富营养化引起的水体“水华”已成为威胁饮用水安全的严重问题。Over the course of two summers, Mr Chen slept aboard a fishing boat, travelling from island to island over the whole chain.
整整两个夏天，陈水华都睡在一艘渔船上，一个岛一个岛地跑遍了整个群岛。This paper summarizes the relationships between the occurrences of harmful algal blooms and the eutrophication in coastal waters.
控制营养输入后，浮游植物生物量或有害藻类水华事件也相应减少。
