Therefore, this paper starts from the river’s external unidirectional character to explain the problem of river pollution in zhejiang province. Then, through the comments of Pigou’s external theory and the Theorem of Coase, introduced the cause of pollution. On these basis, I suggested to reform the system of charging、execute the trading rights of emission Etc. Thus contributing to the effective management of watershed pollution
