Abstract: Water related eco-compensation is an important approach to prevent water environmental deterioration and realize watershed sustainable development. Compensation standard calculation is the key to assess environmental compensation feasibility in specific district. In view of the defects during watershed eco-compensation process, this paper provides the compensation standard implementation foundation considering the theoretical system, management system and operation mechanism at present. Taking the Yongding River basin as the study area, the water related eco-compensation standard conceptual framework was established. According to the indiscerptible attribute of water quantity and quality, watershed compensation standard was illustrated by considering water price and the outflow in the main stream of Yongding River. A set of alternative equations for water quantity compensation under different rainfall probability were developed. Taking into account water quality class Ⅲ as the standard of water quality control, the treatment cost for the contaminated water body was estimated.

Key words: water related eco-compensation standard; water quantity and quality; calculation method; Yongding River basin
