Effects of Nitrogen and Phosphorus Nutrient Salt Structure on Harmful Algae

The harmful algal blooms(HABs) have become worldwide oceanic disaster in recent years,they can not only demolish the oceanic environment,but also seriously damage the aquatic resources,and the nutrient salt structure is one of the important factors causing the frequent occurrence of the toxic HABs.The paper summed up the worldwide research advances in the influences of nitrogen and phosphorus nutrient salt structure on the growth of harmful algae,occurrence of HABs and toxin-producing of the toxic algae,and pointed out the following researches should be strengthened: controlling the structure of the let nitrogen and phosphorus,biogeochemical process of nitrogen and phosphorus,as well as algal absorptive dynamics to nitrogen and phosphorus.
