Development and Application of Models for Analyzing Water Resource Use and Development within a Regional Framework of Economic Growth and Environmental Quality

摘要

Soil sediment and associated materials from agricultural sectors were indicated to be one of the principle substances in determining the water quality. Phosphorus compounds and pesticides were shown to be pollutants associated with sediments. Taxation or effluent charges are discussed as policy instruments for maximizing water quality in the control of point sources of pollutants. However, treatment standards rather than taxation on charges were shown to be more effective in the control of diffused sources, such as agricultural practices. Regional control by some form of basin-wide authority was shown to be best for achieving and maintaining quality levels as inherent components or water quality management.
