【Abstract】 Proceed from the fundamental equation for the temporal and spatial distribu- tion of dissolved oxygen in stream, some factors affected to the concentration of dissolved oxygen as well as means evaluating them are described and approached respectively, thereby the one-dimensional mathematical model for the temporal and spatial distribution of disso- lved oxygen in stream is proposed. The model may be used to establish the appropriate collection of field data and survey procedures and determine the wastewater treatment requ- irements and effect of any natural or artifitial change in the environment, thus it is of great importance to the economic analysis and environmental planning of the drainage basin.更多还原
