The study made a monetized valuation of eco-service provided by forests at Saihanba Mechanic Forest Farm in terms of water conservancy, soil conversation, carbon sequestration, micro-climate adjustment, air quality improvement, protection for agriculture, biodiversity maintenance, and landscape & recreation. The results revealed that the total value of various eco-services is 3.061 billion yuan/a, while the eco-services of unit area forest values at 42 300 yuan/(ha·a).
