[Problems and improvements of water conservancy projects combined with schistosomiasis control in river beaches].

Water conservancy projects combined with schistosomiasis prevention and control are crucial measures to change the habitats of Oncomelania hupensis and are helpful for schistosomiasis control. In this paper, the epidemic characteristics of O. hupensis in lake regions are elaborately analyzed. Also, the specialty problems and applications of the different projects in lake regions are exhaustively discussed. According to the above analysis, some measures and improvements are propounded to deal with these problems.
