This paper uses potential function to build a coupling model: firstly, it divides forest value into three subsystems including economic value, ecological value, and social value, and set the index according to their characteristics; then it studies empirically the coupling relationship among economic value, ecological value, and social value of forest in China from 2008 to 2016. The results show that from 2008 to 2016, the overall coordination among economic value, ecological value, and social value of forest in China is poor while the overall trend is continuous growing, and ecological value of forest has a higher weight. In the future, China should pay attention to the development, protection and utilization of ecological forest value to achieve their sustainable development.
