【摘要】：利用位于廣西廉州灣的自動監(jiān)測浮標(biāo)從2010年開始監(jiān)控到的水華監(jiān)測數(shù)據(jù),分析水華發(fā)生前后溶解氧、pH、葉綠素等數(shù)據(jù)變化,結(jié)合氣象、浮游植物密度數(shù)據(jù),探討不同赤潮藻增殖過程環(huán)境因子的變化規(guī)律,為赤潮機理及預(yù)警預(yù)報研究提供科學(xué)參考。廉州灣水華的葉綠素自動監(jiān)測數(shù)據(jù)高值范圍為24.5~77.0μg/L,浮游植物優(yōu)勢種為硅藻,浮游植物密度接近赤潮爆發(fā)的閾值。自動監(jiān)測浮標(biāo)能捕捉并監(jiān)控到水華發(fā)生全過程,其長時間高頻率的觀測資料可有效應(yīng)用于水華及赤潮的預(yù)警預(yù)報。不同藻種水華的自動監(jiān)測數(shù)據(jù)變化具有差異性,在進行水華預(yù)警時應(yīng)綜合考慮葉綠素、溶解氧以及pH的變化。氣象因素是水華誘發(fā)的因素,降雨過后,氣溫突升,風(fēng)速小于等于三級時,可結(jié)合自動監(jiān)測網(wǎng)絡(luò)監(jiān)測數(shù)據(jù),發(fā)布水華預(yù)警。
[Abstract]:Using Shui Hua monitoring data from the automatic monitoring buoy in Lianzhou Bay, Guangxi since 2010, the changes of dissolved oxygen pH, chlorophyll and other data before and after Shui Hua were analyzed, combined with meteorology. Phytoplankton density data were used to study the variation of environmental factors during the proliferation of red tide algae. The high value of chlorophyll automatic monitoring data of Shui Hua in Lianzhou Bay is 24.5 渭 g / L, and the dominant phytoplankton species is diatom. Phytoplankton density is close to the threshold of red tide outbreak. Automatic monitoring buoy can capture and monitor the whole process of Shui Hua. The observation data of long time and high frequency can be effectively applied to the early warning and forecast of Shui Hua and red tide. There are differences in the automatic monitoring data of the different algae species Shui Hua, so chlorophyll should be considered comprehensively in the early warning of Shui Hua. Do and pH changes. Meteorological factors are caused by Shui Hua. After rainfall, the temperature rises suddenly, the wind speed is less than three levels, can combine with the automatic monitoring network monitoring data, issue Shui Hua early warning.
