In this paper, we first examine the characteristics of optimal economic growth under a given environmental regulation. The phanse diagrams make it easy to graspe the transition from any one situation to other. Second, we propose to apply the fuzzy control to the determination of the regulation on discharged pollutnant.The economic growth in this paper is patternised into two phases; in one of which the pollutant discharged from usual productive activity should be reduced through the operation of the cleaning activity, while in the other need not. And each phase is further divided into two cases according as the current product in wholly consumed or not.The fuzzy control introduced in determining the value of regulative parameter proves to be effective, in that it copes with the fuzziness such as one concerning how rapidly the level of pollutant should be reduced, in that it facilitates to determine the value of parameter taking account of the locational distribution of the economic agencies emitting the contamination and those suffered from it, and in that it enables us analyse simultaneously, though not completely, the intertemporal behaviour of the capital stock and level of pollutant.
