【摘要】：本研究利用高分辨率的GF-1衛(wèi)星影像對MODIS數(shù)據(jù)綠潮監(jiān)測的精度進(jìn)行驗證,并在此基礎(chǔ)上利用MODIS數(shù)據(jù)對2016年黃海綠潮過程進(jìn)行連續(xù)動態(tài)監(jiān)測,結(jié)果表明:相較于GF-1衛(wèi)星影像,MODIS數(shù)據(jù)對綠潮的監(jiān)測誤差高于50%;2016年黃海綠潮移動路徑總體呈先向北,然后沿山東半島海岸線向東北方向移動,并最終停滯于青島、威海附近海域;此次綠潮持續(xù)時間為80天左右,并呈現(xiàn)出與往年類似的"出現(xiàn)→發(fā)展→暴發(fā)→治理→消亡"的規(guī)律;其中"出現(xiàn)"的時間為5月12日,"發(fā)展"階段時間為5月中下旬,此時綠潮主體分布于蘇北渾水區(qū),適宜前置打撈治理,當(dāng)5月底6月初綠潮進(jìn)入清水區(qū)之后才開始進(jìn)入"暴發(fā)"階段,本年度綠潮災(zāi)害"暴發(fā)"規(guī)模較大,對山東沿海水產(chǎn)養(yǎng)殖業(yè)及旅游業(yè)影響嚴(yán)重。本研究成果對于綠潮預(yù)警和防控具有科學(xué)和實際意義。
[Abstract]:The high resolution GF-1 satellite image is used to verify the accuracy of green tide monitoring of MODIS data, and on this basis, the continuous dynamic monitoring of Huang Hai green tide process in 2016 is carried out by using MODIS data. The results show that compared with GF-1 satellite image, the monitoring error of green tide is higher than 50. In 2016, Huang Hai's green tide movement path was first northward, then moved northeast along the coast of Shandong Peninsula, and finally stagnated in Qingdao, near Weihai. The green tide lasted about 80 days and appeared to be similar to previous years. 鈫扗evelopment. 鈫扥utbreak. 鈫扜overnance. 鈫扵he law of extinction, in which the time of "appearing" is May 12th, and the period of "development" is the middle and late period of May, when the main body of green tide is distributed in the muddy water area of northern Jiangsu Province, which is suitable for pre-salvage treatment. When the green tide entered the clear water area at the end of May and the beginning of June, it began to enter the stage of "outbreak", and the scale of the "outbreak" of the green tide disaster in this year was relatively large. The results of this study are of scientific and practical significance for early warning and prevention and control of green tide.
