With the development of forestry construction and the enhancement of management intensive degree, the requirements for the investigation of stand growth are getting higher and higher. Forestry management is inseparable from the growth of this important information. At present, there are some problems in the survey of stand growth, no matter in the way of data collection, tabulation method, the form and precision of the result. In order to achieve the purpose of uniform method, uniform standard and uniform specification of stand growth survey, this paper takes “orthogonal design” as the basis and makes a study on the method of stand growth survey.
