【Abstract】 A summary is made on the background, developing process, and structural frame of the TMDL program that is issued by U.S. EPA. The main content of the program, the method of how to confirm the key management area of water quality, and the ways of evaluation of pollution sources and estimation of the capacity of pollution loads in the program are introduced. Finally, some suggestions are made on the control and management of non-point source pollution in China, such as development and implementation of the TMDL program in stages with emphasis placed on different areas and some key points, development of a simple, practicable, and economical model and technical measures for evaluation of the capacity of pollution loads, and combination of the TMDL program with other measures for pollution control within the range of total amount pollutant control with public participation and comment included in the program.更多还原
