title: The comparison of phosphorus pools from the sediment in two bays of Lake Dianchi for cyanobacterial bloom assessment.
abstract: The different pools in the sediment from two bays with different scales of cyanobacterial bloom were studied to assess the trophic status. With large scale of cyanobacterial bloom in Haigeng bay the concentrations of different phosphorus fractions were higher than the corresponding concentrations in Macun bay, and especially WSP and AAP are the most evident, which indicates that there are more available and potential available phosphorus in Haigeng bay. The adsorption experiment also shows that the sediment in Haigeng bay is more saturated than that in Macun bay. Haigeng bay can be faced with the more serious ecological danger. Furthermore the death and deposit of a mass of algae can contribute to phosphorus released from sediment and help to the breakout of newborn cyanobacterial blooms.
