Abstract：In nature, most species show a 1: 1 gender ratio at birth. However, seven -larhocyst species have the ability to adapt to the change of gender proportions. In order to consider the impact on the ecosystem due to the lack of food, the sedentary lamp eel population has changed the ecosystem, this article collects the relevant data of the Marine Milky Eel from the US Geological Survey. After the data processing Introduce gender-based population dynamics, establish predators (seven homglier eel) -D dynamic equations in prey, in order to consider the impact on the ecosystem when changing the gender ratio of seven-mortified eel population, introduce random errors to eliminate uncertainty and use The numerical simulation method has obtained the change of gender proportions to have a significant advantage in the larger ecosystem. Two two as an ecosystem stability indicator based on the biological abundance and nutrition structure. The change in the gender ratio of seven -larhoma will promote the stability of the ecosystem.
