We are grateful to numerous colleagues, students and staff from the Central South University of Forestry and Technology for their hard work and assistance in the establishment of the small experimental watersheds and the permanent sample plots and in the observation, measurement and data calculation in the Station over the past 30 years. The authors wish to express their thanks to the Department of Forestry, Huitong County, for granting us access to the research sites. The long-term research project has been funded by China’s Ministry of Forestry, the National Natural Science Foundation and National Field Observation grant. We are also grateful to the journal of Forestry editor and two anonymous reviewers for their valuable comments and suggestions.

Since the 1970s, a long-term research project has been conducted to monitor the changes in primary productivity of Chinese fir plantation at Huitong Ecosystem Research Station, Hunan, China.
