青岛近海赤潮灾害分级与时空分布及赤潮生物的变化
Spatial-temporal Distribution and Hazard Grading of Red Tide and Variation of Red-tide Species in Qingdao Adjacent Sea Area
摘要
Abstract
Red tides occurred in Qingdao adjacent sea area were classified into five levels,i,e.,extra large, large,moderate,mild and slight,according to the red tide scales and hazard types.Thirty-three red tide events were recorded from 1990 to 2013 with the main types of slight red tide and mild red tide.Among them,the scale of red tides was less than 10 km2 accounting for 5 1 .5%of the total red tides and 60.6%of the red tides were caused by harmless red tide species.Jiaozhou Bay and Fushan Bay adjacent sea area were the red tide-frequent-occurrence areas.The frequencies and scales of red tides peaked every four to five years from June to August,with the main red tide species of Mesodinium rubrum and Noctiluca scintillans.The species of red tide gradually increased with a rising tendency of Pyrrophyta occurrence frequency,even rare species have appeared in the past few years.The changes of the red tide species indicated that the species composition of phytoplankton in Qingdao inshore area has changed,which is closely related to the marine environment of Qingdao near-shore areas.关键词
