摘　　要：针对在2006年夏天渤海湾赤潮重点监控区中发生的一次夜光藻赤潮，考虑到夜光藻赤潮过程与环境因子的复杂关系和赤潮监测数据的不确定性，利用模糊逻辑方法对监测数据样本进行了分析。本文的研究对象为1号、2号和4号站位包含有夜光藻赤潮过程的7月26日～8月20目的连续监测数据，给出了隶属度函数和模糊规则的提取方法，利用生成的模糊逻辑规则阐述了此次夜光藻赤潮的生消过程并分析了夜光藻赤潮与若干环境因素之间的变动关系，为进一步研究该海域的夜光藻赤潮机理并预测夜光藻赤潮奠定了基础。Noctiluca Scintillans is one of major algae of Chinese coastal area, which was found in the intensive monitoring area of Bohai Bay in summer 2006. For the case of uncertainty of monitoring data and the complexity of the relationship between the abundance of N. ScintiUans and the environmental factors ,the data analysis was done by the fuzzy logic approach. The monitoring data between 26 Jul. and 20 Aug. were taken into the considering model of the relationship between the blooms of N. Scintillans and environmental factors. The method of abstracting fuzzy membership and rules for fuzzy model were described. In accordance with the monitoring data of red tide in BoHai bay, the result of fuzzy inference between a few environmental factors and the blooms of N. Scintillaas is considered. The foundation is established for further research and forecasting the blooms of N. ScintiUans.
