| It is a high focused problem by people that how to utilize the wood resource reasonable and high beneficially. The paper use the bark of Salix which is rich planted in Inner Mongolia as the test materials. Study on the fiber configuration, chemical component and character of hot-reaction of Salix bark. Base on above study, the Salix bark effect on the properties of particleboard was studied recur to whole gene design. And work on the process of Salix bark board, using uniform design and regression analysis algorithms to study the technical parameters and establish the math model of technical parameters and the testing gene. All the parameters were tested in the paper use the standard of American System of Testing and Material (ASTM).Through research and analysis of data, it was observed that the length and width of bark fiber varied according to the lop and age, the results show the fiber of the Salix bark is longer than the Salix and width of fiber almost same, fiber length of the Salix bark mainly influenced by the times of lop. The ash in Salix bark,1% Sodium Hydroxide Solubility in Salix bark, water solubility in Salix bark, Ethanol-Toluene in Salix bark, acid-insoluble lignin in Salix bark changed with the lop and age is also been investigated, the component of Salix bark is higher than Salix except acid-insoluble lignin,and it's high effected by times of lop; the TG analysis and DSC analysis is been used on the Salix bark and Salix to study the character of the hot-action, and the rang of the pyrogenate temperature is confirm; the quantity of Salix bark effect on the MOR, MOE, swelling in 24h water, nail withdraw and inner strength was determined, the results show that the Salix bark notability effect on the properties of board and dropped it; the properties of the Salix bark board is nearly the board product by other bark residues, it was established the multi regression equation of each properties and optimized the fitting produce condition of Salix bark board.
