I apparently have ever heard that an tendency for dominant algal bloom-forming species was from diatoms to dinoflagellates in most parts of the world. Is that ture? Which paper have mentioned this view ? Thank you!
I am afraid your question is too general. Do you mean fresh or sea water? "Most parts of the world" doesn't make it easier. In general, in seawater, an increase in N+P, not Si (a nutrient for diatoms, not for dinoflagellates and most other bloom-forming "flagellates" such as prymnesiophytes and raphidophytes) gives "flagellates" a relative advantage over diatoms. I don't think there is one paper answering your question.
Definitely the question needs narrowing down. Cyanobacteria are another common bloom-forming group of phytoplanktonic organisms.
Dear Peperzak et al.,
Thank you for you answers! I'm sorry about that I should say in sea water. I knew my question was too broad to answer, but an deep impression in my mind is that an tendency for change of dominant bloom causitive species (from diatoms to dinoflagellaes) just likes an tendency for variatiion of phytoplankton community (from mcrio- sized to nano- and pico- sized) in most parts of world in seawater (I'm not sure whether I should say in most parts of world in seawater ). Somewhere in China , situation like you mentioned was happening and became orderly, diatoms bloom-forming in early spring ,then when Si exhausted, dinoflagellaes grow vigorously to form another new bloom. So, I just wonder if this situation was common in other countries.Thank you !
Best regards!

I think that the works of Ramón Margalef somewhat to respond to your question.

Dear Chen, Dominant forms of bloom forming pjhytoplankton could be cyanobacteria in freshwater bodies and flagellates in seawater
Dear Gerdzhikov and Edavilakathil,
I'm sorry to reply so late because I worked outside 11 days ago. Yeah, This question may be a conundrum, and it is difficult to answer it in a few words.Thank you for your help, and I'll keep on learning.
Best regards,
Zhenfan
