【摘要】：本研究利用高分辨率的GF-1卫星影像对MODIS数据绿潮监测的精度进行验证,并在此基础上利用MODIS数据对2016年黄海绿潮过程进行连续动态监测,结果表明:相较于GF-1卫星影像,MODIS数据对绿潮的监测误差高于50%;2016年黄海绿潮移动路径总体呈先向北,然后沿山东半岛海岸线向东北方向移动,并最终停滞于青岛、威海附近海域;此次绿潮持续时间为80天左右,并呈现出与往年类似的"出现→发展→暴发→治理→消亡"的规律;其中"出现"的时间为5月12日,"发展"阶段时间为5月中下旬,此时绿潮主体分布于苏北浑水区,适宜前置打捞治理,当5月底6月初绿潮进入清水区之后才开始进入"暴发"阶段,本年度绿潮灾害"暴发"规模较大,对山东沿海水产养殖业及旅游业影响严重。本研究成果对于绿潮预警和防控具有科学和实际意义。
[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.
