摘　　要：本文利用模糊模式识别交叉迭代模型对分布于乌梁素海各水功能区的21个水质监测点，2009年5月～10月的富营养化等级进行了模糊模式识别研究；并利用Arcview的空间分析功能，绘制富营养化等级识别结果的空间分布月变化Grid图。将富营养化状态识别结果及其分布区域与乌梁素海同期水质监测指标浓度变化及其分布区域进行对比分析及验证。识别结果与实际水质状况相符，验证了该方法的有效性。A cross iteration fuzzy recognition model was aplicated to recognize trophic state grades of lake. Trophic state grades of water quality from May. 2009 to Oct. 2009 of 21 monitoring stations distributed in Wuliangsuhai Lake, which located in arid area of Inner Mongolia, China, was recognized by the model. Based on Arcview, Monthly change Gird themes were established about distraction of trophic states grades. Analyzed the recognition results and the monitoring data contrastively, conclusions can be draw： The recognition result correspond with the practical situation, and can reflect change of trophic state grades in spatial - temporal distribution well.
