Abstract: Evaluating the service functions of forest ecosystems is conducive to realizing the capitalization of forest resources and optimizing the protection and management of forest resources. In this study, we reviewed the research progress on the evaluation of the service function value of forest ecosystems in China during 2010 to 2021. There were significant differences in the value of various service functions of forest ecosystems in China. Among them, the largest was water conservation, followed by soil conservation, carbon sequestration and oxygen release, biodiversity conservation, air purification, forest recreation, forest product supply, forest protection, and nutrient retention. The service functions of mountain and urban forest ecosystems were highly heterogeneous. The main contributions of mountain forests were water conservation (36.94%), soil conservation (18.68%), biodiversity conservation (17.67%), and carbon sequestration and oxygen release (12.44%), while the main contributions of urban forests were carbon sequestration and oxygen release (29.37%), water conservation (22.49%), air purification (16.93%), and soil conservation (11.68%). Broadleaved evergreen forests had the highest values of ecosystem services, followed by deciduous broadleaved forests, mixed coniferous forests, and coniferous forests. In the past decade, although the evaluation method of forest ecosystem service value had been greatly enriched, there was still much room for improvement, especially in establishing indicator system. To provide a scientific foundation for the sustainable development of ecosystems and ecological environment construction, we must further optimize measurement methods and technical means, improve data acquisition capability, and strengthen the integrity and scientific nature of ecosystem service function assessment, which lays a foundation for the research on the realization path of ecosystem service value.
