Abstract:

The confirmation method of mature level in uneven-aged forest is an insoluble problem both in forestry theory and forestry production at present. There are two problems. First, it must be measured and counted by the trees' diameter. The rank of the trees' age can't be used in the forestry production. Second, the comparison among the forests of different trees' diameter in three-dimensional space must be finished. In this paper, the confirmation method by giving an example of the confirmation from a formula which divided the price of a certain trees' diameter by the volume of timber was studied. It will not only get the most profit economic part but also protect the forest most as well. The basic foundation of the solution which can reduce the blindness in cutting uneven-aged forest was provided.

Key words: uneven-aged forest, mature, confirmation method
