The sex ratio of lampreys has some effect on the ecosystem. To examine the impacts of changing sex ration ecosystem, the paper used logistic model to describe the relationship between sex ratio and food resources. The paper established a comprehensive population dynamics model by adding different niche and food web influence conditions, and then used a weighted scoring model to analyze the impacts on ecosystem. To investigate the strengths and weaknesses of lamprey populations in the ecosystem, data were first collected and analyzed in contrast to the data of lamprey populations from other biological populations. Factors with large differences after comparison of different data were mainly selected as influencing factors. On the basis of the original, the population dynamic model was improved, and the advantages and disadvantages of the population were analyzed by the weighted scoring model. Sorts through the above analysis can understand the advantages and disadvantages of its species change sex ratio ability, and the mutual influence between and ecological system.
