China runs several biggest forestry programs in the world. Improved use of these forests and the newly planted forests should provide multiple benefits for Chinese people. The success of ambitious forestry policy depends not only on the huge resources invested in it and on a strong political will but also on the expertise required in order to fulfil the task in the correct manner. Transfer scientific expertise into forest policy making is becoming one of the success factors of China’s forestry development. Examples from other parts of the world show that the relation between forest science and forestry policy is very sensitive. In this paper, forest science and forestry policy monitoring and evaluation systems in China are described; problems and challenges of these systems are identified; the model of transfer scientific expertise into real policy is analyzed; three main factors which positively influence the practitioner’s acceptance and utilization of expertise are discussed; some conclusions and suggestions are conducted finally.
