    Abstract: The present paper introduced mathematical model for transmission of schistosomiasis especially about Barbour's two-host model suitable for Schistosomiasis japonica and elaborated the theory of transmission dynamics of schistosomiasis.It is proposed that the concept and the formula of transmission capacity i.e.basic transmission veloci-ty of schistosomiasis from the concept of basic reproduction rate.Through the dynamics calculation for fields data the endemic characteristics of schistosomiasis were revealed.This paper also introduced the possibility of using the models for evaluating and predicting the effect of various control measures.
