摘　　要：从生态系统的观念出发,利用生物个体的自适应、自组织和自学习能力的结构单位——生态位。在模糊系统中引入生态位理论,利用生物自身的自适应性,设计具有生物特性的Type-2模糊系统,并讨论Niche-Type-2模糊系统的万能逼近性,同时,为通常的模糊系统赋予了明确的生物意义。实例研究结果表明,该方法所给出的模糊规则含义明确,逼近效果好,稳定性高,并具有较强的抗干扰性。This article from the ecological system perspective, the use of biological individual adaptive, self-organizing and self-learning ability of structural unites ecological niche. In fuzzy systems using the ecology theory, the use of biological self adaptability, design with the biological characteristics of Type-2 fuzzy system, and discuss the Niche Type-2 fuzzy system of universal approximation property, at the same time, as the usual fuzzy system gives a clear biological significance. The study results show that, the method proposed fuzzy rules meaning clear, approximation effect is good, high stability, and has strong anti jamming.
