Based on the Logistic dynamic population model, this paper studies the effect of sex ratio change on ecosystem. Taking sea lampreys as the research object, the population dynamic model, sex ratio model and food chain model were constructed. The results showed that the change of sex ratio would affect the population fluctuation, food chain structure, niche utilization and ecosystem stability of sea lampreys. The advantages and disadvantages of sex ratio change on Lampreys population were analyzed by AHP. The results show that sea lampreys have good environmental adaptability, can control parasites and adapt to predator threats, but there is adaptability to fishery behavior and sensitivity to environmental resource changes. This study provides an important reference for understanding the complex effects of biological sex ratio changes on ecosystems.
