摘要：An economic analysis of policies to control nonpoint source nitrate pollution in the presence of minimum river flow restrictions was undertaken. A non-linear bio-physical economic optimisation model of an intensively cultivated Scottish agricultural catchment was constructed. The presence of minimum river flow controls in the catchment was found to reduce nitrogen pollution. However, by themselves, river flow controls were found not to be a cost effective means to reduce diffuse pollution. River flow controls did not, for the most part, alter relative instrument ranking.
