Rizhao offshore was selected as the study area in monitoring the Enteromorpha Prolifera. Using the floating algae index (FAI) which is based on the remote sensing technology and geographic information system with MODIS global surface reflectance data, the authors interpreted and extracted the Enteromorpha prolifera information in Rizhao offshore. Temporal and spatial evolution characteristics of 2012 and 2013 were studied through these methods. Combined with the sea surface temperature data and the precipitation provided by TRMM satellite, the relationship between Enteromorpha prolifera and the meteorological factors were revealed. The results can provide information about controlling and alleviating the harm of Enteromorpha prolifera. Some conclusions have been reached:The intensity and distribution areas of Enteromorpha prolifera could be well revealed by using FAI index from May to July in 2012 and 2013. The information about Enteromorpha prolifera by using threshold indicates that the intensity and the areas of Enteromorpha prolifera in 2013 was stronger than that in 2013. Temperature and precipitation have great influence on the thriving of Enteromorpha prolifera. The temperature between 20℃ and 21℃ is the best interval for the growth of Enteromorpha prolifera, and the increasing of precipitation is also important for the increasing of Enteromorpha prolifera. In short, hydrographic and meteorological condition in 2013 was more suitable for thriving of Enteromorpha prolifera than that in 2012.
