Abstract: This article is based on the practice of production of wood in the Cutting Chances in Fujian and the calculation method of probability regression in the theory of quantization is used for developing the mathematical forecast model of the choice of the technological types of wood production in cutting chances. With the application of this model, twenty cutting chances were predicted in 1982 that the average relative error of their labour productivity is 3.39 percent and that of production cost is 3.58 percent.
