Abstract:The tanget system to be evaluated is a complex system, which is closely related to the forestry socialeconomic system. It is almost impossible to describe and evaluate the behavior and results of this system with a single index. The strength evaluation system, which contains the second class indexes of Input, activity and Output, has been established according to the results obtained and inquiry among nearly 100 specilists who are engaged in the acadmic, educational, productive and adminstrative departments. The third class indexes such as personnel, funds, research projects, outcomes of scientific research, instrument and equipment, information, number of pressed research paper, forestry education, international cooperation and exchange have been analysed in this paper. We conclude from the index analysis that the chinese forestry science and technology possesses fairly good basis in research conditions, but is weak in strength. The paper points out that, if some effective measures are taken to enhance the forest scientific and technological strength, it may undertake the task in some scope to realize the forest economic target of the year 2000 bythe progress of science and technology on certain degree.
