【摘要】：微微藻褐潮在我國(guó)是一種新出現(xiàn)的海洋生態(tài)災(zāi)害。本文針對(duì)秦皇島海域微微藻褐潮高發(fā)區(qū),探討利用衛(wèi)星遙感技術(shù)監(jiān)測(cè)微微藻褐潮的可行性。首先利用MODIS數(shù)據(jù)反演秦皇島海域葉綠素a(Chl a)濃度和海面溫度(SST)判別水色異常區(qū)域,然后通過(guò)HJ-1號(hào)衛(wèi)星真彩色影像中褐潮水體與非褐潮水體之間的水色差異,綜合判讀褐潮,最后以2014年5月秦皇島海域的衛(wèi)星遙感數(shù)據(jù)為實(shí)驗(yàn)數(shù)據(jù)進(jìn)行實(shí)例研究。結(jié)果表明,當(dāng)Chl a≥2.5 mg/m~3和15℃≤SST≤25℃時(shí)為海水水色異常閾值,并且褐潮水體在HJ-1號(hào)衛(wèi)星真彩色影像中呈明顯的黃綠色,該綜合判別法用于微微藻褐潮監(jiān)測(cè)是可行的,這為進(jìn)一步開(kāi)展微微藻褐潮業(yè)務(wù)化監(jiān)測(cè)奠定了基礎(chǔ)。
[Abstract]:Picoalgal brown tide is a new marine ecological disaster in China. In this paper, the feasibility of using satellite remote sensing technology to monitor picoalgal brown tide in Qinhuangdao sea area is discussed. Firstly, the MODIS data are used to estimate the concentration of chlorophyll a(Chl a and the sea surface temperature in Qinhuangdao Sea area to judge the abnormal area of water color. Then the color difference between the brown tidal body and the non-brown tidal body in the true color image of HJ-1 satellite is used to comprehensively interpret the brown tide. Finally, the satellite remote sensing data of Qinhuangdao Sea area in May 2014 are taken as experimental data. The results show that when Chl a 鈮，
