Abstract: The studies of watershed eco-compensation schemes which emphasize water quality efficiency and systematic ecological services value calculation methods remain less. The paper presents watershed eco-compensation standard calculation framework based on water quantity-quality simulation and water ecosystem services value. Considering water quantity and water quality integrity, the paper supplies Yongding River Basin ecological compensation standard across hydrological control sectors. The author gives Yongding River Basin benefit compensation standard by considering ecosystem species and habitats diversity, water body function differentiation from river, forest and wetland system. The benefit compensation value is annual 15 billion yuan in terms of input-output relationship. The damaged compensation standard is annual 1.6 billion yuan by taking into account the opportunity cost of limiting development and water conservation loss. Finally, the paper illustrates the perfection suggestion of eco-compensation standard based on practice result.

Key words: eco-compensation standard, water quantity compensation, water quality compensation, opportunity cost
