In this paper, the relationship was studied bwtween the permeability of Pinus koraiensis, Larix gmelinii, Betula platphylla and Populus davidiana and moisture content of wood in the hygroscopic range. The mathenatical model of variation low has been obtained from the relationship between wood and water, The results are as fellow: (1)The relationship betweed wood permeability and the moisture content is in twice curve function in the hygroscopic rang. (2)There is a peak value in tangential permeability, (3) The number of openings per cm of cross sectionand pit—opening average radii reduces by the increaasing of wood moisture content.
