| 综合利用环境卫星（HJ-1A/1B） CCD影像与MODIS影像，对2011-2017年南黄海海域浒苔信息进行了提取，并结合QuickSCAT海风数据以及ESRL海温数据对浒苔生长及漂移路径的影响进行了分析。结果表明：（1）7年中利用遥感手段最初发现浒苔的日期为5月份，初始发现位置多集中在江苏省盐城市附近海域，且近7年浒苔漂移方向整体上向北，进入山东半岛海域。其中，浒苔中心点距离青岛海域最远约115km （2015年6月21日），最近约9.6km （2012年7月11日）。（2）浒苔中心点漂移方位年际差异较大，整体上浒苔漂移路径方向与海面风风向高度一致。（3） SST是浒苔暴发的关键环境因子，南黄海海域5—8月份SST逐月升高为浒苔生消过程提供了环境条件。 |

| Abstract: |
| Using the environmental satellite (HJ-1A/1B) CCD and MODIS images, we analyzed the drift of inter-annual trajectories of Ulva prolifera in the South Yellow Sea from 2011 to 2017. The effects of sea surface wind (SSW) and sea surface temperature (SST) on the growth and drift trajectories were studied using QuickSCAT sea wind data and ESRL (NOAA Earth System Research Laboratory) SST data. The results show that in the past seven years, the earliest occurrence of U. prolifera bloom noticed by remote-sensing was in May near Yancheng, Jiangsu. In general, U. prolifera bloom drifted south to north from northern Jiangsu to the southern part of the Shandong Peninsula. The most distant U. prolifera bloom was centered 115km east off Qingdao on June 21, 2015, and the least distant one was 9.6km off Qingdao on July 11, 2012. The central position of the bloom varied considerably, and the overall route of the drift agreed well with the wind direction at sea surface. SST was the key environmental factor for the bloom outbreak. The monthly SST increase in May-August in the southern Yellow Sea predestinated the on-and-off of the algal bloom. |
