摘　　要：为了解秦皇岛海域赤潮的发生情况,通过利用预处理后的MODIS遥感数据,针对单波段比值法的不足,提出了多波段差值比值法来提取赤潮信息,并对两种方法进行了对比实验。实验结果证明多波段差值比值法提取的位置及面积与事实更加相符,说明该方法更适合秦皇岛海域的赤潮监测。In order to understand the occurence of red tide in Qinhuangdao sea area,a multi—band diference ratio method was proposed to extract red tide information by using pre-processed MODIS remote sensing data and aiming at the deficiency of single—band ratio method .The experimental results show that the location and area extracted by the multi一band difference ratio method are more consistent with the facts.This method is more suitable for red tide monitoring in Qinhuangdao Sea Area.
