In 1859, Charles Darwin published his book named "Origin of Species". From then on, a new biological evolution theory with the kernel natural selection was born. By means of the theory of common ancestor, Darwin explained the origin of life and unified the biodiversity. At the same time, the survival struggle theory gives a scientific description to the relationship between the organisms and their environments. Two-theory illustrate united the organic and non-organic together. As the result of this, the ecological niche theory plays an important role in the researching process of on ecology.How to provide a proper explanation to a complicated ecosystem puzzles most of the ecologists for a long time. As far, it has proved that the neutral theory is best frame of reference. At present, most of the neutral-ecological models own a single reproduction mode. In order to describe the ants and bees ecosystem lucidly, we introduced a mixture reproduction actions when researching a complicated ecosystem. In this paper, we will focus on the biodiversity impact factors for the eco-system with the blended propagation. As we know that each individual has its own reproduction action, area and any mutation action ect, and their different character will cause a profound effects on its ecological diversity. Similarly the simulation results indict that any animal with different natality, mortality, migrate, propagate mode and so on will cause a profound influences for the biodiversity for this system. At the same time, this essay gives a detailed analysis on the impacts engendered by blended propagation.
