摘　　要：Aim To study the relationship between the changes of ecology and environments and the transmission of Schistosomiasis japanica after the construction of the three gorges reservoir.Methods Based on predictive data supplied by the Yangtze River Committee on Water Conservancy,of the changes of the water level and sediment in the middle and lower reaches of the Yangtze river after the dam construction, corresponding data were collected and mathematics model was extablished by field pilot studies. In order to understand the effects of changes of water level and sediment on the growth 4 distribution of Oncomelania hupensis which is the intermediate host of Schistosoma japonicum, field surveys and ecologically intimated experiments were done.The prevalence status and factors related to transmission were investigated by methods of epidemiology, geographical medicine and social medicine.Results 1 The Three Gorges Project is an integrated project in a large scale to exploit and improve the environments of the Yangtze River. It will have a profound effect on improving and accelerating China’s social and economic development. 2 Positive impact on control of Schistosomiasis after the construction of The Three Gorges Reservoir:After the dam construction, the decrease in the frequency of flooding in Yangtze River will be occurred which cease the diffusion of snails and decline the chances ofinfectionofhumanandlivestock. Snails habitats will be reduced in the flushed areas along the Yangtze River. Exploitation of beaches and delimination of snails will be benefited from the beach’s uplift in the flushed areas. And the floods that will be ahead of time in autumn will interfere the development of snails.3 Negative impact on control of Schistosomiasis after the construction of The Three Gorges Reservoir:The flushed beaches and migrator’s settlements in certain altitude may become snail habitats.The reservoir areas will become the potential transmission areas of Schistosomiasis due to diffusion of infectious resources and Onco
