摘  要：
绿潮作为一种新型生态灾害自2007年以来在江苏沿岸海域频繁发生,对江苏海洋生态环境造成影响。基于2014年MODIS数据,分析获得江苏绿潮发生时间、面积、影响范围及漂移路径。结果表明:绿潮最早发生于四月下旬,浒苔在2014年5月生长增殖速度最快,覆盖面积达到全年最大值。2014年6月至7月绿潮进入爆发期,8月逐渐衰退,9月中旬在遥感影像上趋于消亡并处于相对稳定状态。浒苔无毒并具有一定营养价值,但绿潮爆发改变海洋原有生态环境,造成生态系统紊乱,对海洋渔业生产造成影响。浒苔堆积氧化变质亦对生态环境造成污染进而发生次生灾害。开展浒苔无害化处理及资源化利用是解决浒苔爆发引发一系列环境问题的有效途径。

摘  要：
As a new kind of ecological disaster, the green tide has been a kind of frequent natural disaster since 2007 in the Jiangsu coastal area which has made great differences in the marine ecological environments of Jiangsu Province. According to the MODIS Data of 2014 we can get the information of the green tide of Jiangsu Province, such as the occurred time, the area, the effect area and the drift path. The results show that the green tide has happened in the late-middle of April at the earliest time and in May 2014, the multiplication rate of the Enteromorpha prolifera is the fastest and the cover area is the maximum of the whole year. From June 2014 to July 2014, the green tide has been in the outbreak period and in August 2014 it is declining while in the middle of September, it is in the dying and stable state on the remote sensing image. The Enteromorpha prolifera is non-poisonous and it also has the nutritional value. However, the outbreak of the green tide will change the original ecological environment of the sea which will not only cause a marine ecosystem disorder but also affect the marine fishery production. The oxidative deterioration of the Enteromorpha prolifera will also pollute the environment and cause a secondary disaster. The bio-safety disposal and the optimization of resource distribution are the efficient path to solve the series of problems caused by the outbreak of the Enteromorpha prolifera.
