Abstract: Aiming at the research status and existing problems of pollutant emission rights allocation, a two-level allocation mode based on water functional areas is put forward. At the view of the ecological and environmental protection and water resources sustainability, a multi-objective optimal allocation model is established for river pollutant emission rights, which takes economic benefit optimization and water quality optimization as its objective functions, and concentration, total quantity of the pollutants, allocation equality as constraints. The model is applied in Jushui River. Practical results and conclusions are obtained, which proves validity and applicability of the model and provides scientific gist for River Environmental Protection Agency.

Key words: river pollutant emission rights, two-level allocation mode, optimal allocation, water functional areas, equality
