【摘要】 物种间的竞争、共存和协同进化是物流生态系统中物种生态行为演进的主轴，也是物流产教融合协同演化发展的基础。文章以Lotka-Volterra种间竞争模型中的模糊竞争系数为研究对象，对种群间竞争系数小于1情况下的种群共存状态行为进行了探索。借助模糊集理论分析研究发现，种群间的模糊竞争系数可以被看作水平截集运用到Lotka-Volterra模型中。模糊竞争系数的取值范围有一定的关联性：（1）竞争种群的水平截集取值小于0.5时，对应种群竞争系数的下确界由竞争种群的水平截集确定。（2）竞争种群的水平截集取值大于0.5时，对应种群竞争系数的下确界为0.5。更多还原

【Abstract】 Inter-species competition, coexistence and co-evolution are the main axes for the evolution of species’ ecological behavior in logistics ecosystems, and also the basis for the synergistic evolution and development of logistics industry-education integration. In this paper, the fuzzy competition coefficient in the Lotka-Volterra interspecific competition model is used to explore the coexistence behavior of the populations in the case of interspecific competition coefficient less than one.With the help of fuzzy set theory analysis, it was found that the fuzzy competition coefficients between populations can be viewed as horizontal intercepts applied to the Lotka-Volterra model. The range of values of the fuzzy competition coefficient is somewhat correlated:(1) When the horizontal intercept of the competing populations takes a value less than 0.5, the lower definitive bound of the competition coefficient of the corresponding population is determined by the horizontal intercept of the competing populations.(2) When the horizontal intercept of the competing populations takes a value greater than 0.5, the lower definitive bound of the competition coefficient of the corresponding populations is 0.5.更多还原
