本文利用2000-2013年每年5-9月MODIS影像数据，根据FAI（浮游指数藻类指数）提取洞庭湖水华的面积和空间分布信息，探求洞庭湖水华产生的时空分布规律及特征，从而为洞庭湖水华的预防和治理提供支持。结果表明：洞庭湖在2008年以前无水华爆发，水体整体基本处于中营养状态；2008-2010年，水华爆发程度达三级；到2011年，水华爆发面积减少，爆发程度稍有减低。水华爆发区域主要集中在东洞庭湖。

By using the MODIS image data of May to September each year of 2000-2013, this article extracts area and spatial distribution information on the water blooms of the Dongting Lake according to the FAI (planktonic algae index) to, searches the time and space distribution rule and characteristics of Dongting Lake water blooms, and provides support for the prevention and treatment of the Dongting Lake water blooms. The results show that there is not water blooms outbreak of the Dongting Lake before 2008, and the water is in the state of nutritional status;the blooms outbreak is up to level 3 in 2008-2010;and by 2011, the area of the blooms outbreak is reducing, and the degree of outbreak slightly reduced. The water blooms outbreak area mainly concentrates on the east Dongting Lake.
