The Law of Change for Biological Species and Groups as well as Its Practical Significance

Han Fengqing Li Hongmei  
Based on the feature that the age structure of species and groups scatters,but they are dying successively,the author adopts a continuous and scattering function to express the number of species and groups.With the differential equations and Leslie matrix,we find some rules about the change in numbers of biological species and groups.Some proposals are given on how to protect resources and how to maintain a steady economic growth.
