Wood preservation can prolong the service life of wood, guarantee a sparinguse of timber and obtain significant economic and social benefits. (1) All countries inthe world make a high estimate of wood preservation. (2) Kinds of preservatives tendto become diversified along with the expansion of the scope of their application.

(4) Advantage of modern science and technology is taken of touninterruptedly improve the preserving technique and to help it attain the objective ofautomation. Wood preservation in China started in 1950s. Much progress has been madein the past forty years, but the quantity of wood preserved is only 1% of the yield. Notonly the quantity of wood preserved is very small, but the kind of preservatives used isalso less in number. For these reasons, the author gives points in recommendation forthe future development of wood preservation in China. (1) Give a full play to thepotentiality of the existing production equipments (large, medium and small types)(2) Strengthen the organization and leadership. It is better for the wood preservationto be under the unified supervision and control of the State Planning Commission. (3)Leaders at all levels should pay more attention to the importance of woodpreservation. Regulations and technical specifications concerning wood preservationshould be laid down by government, and be put into effect under the supervision of gov-ernment. Wood preservation should be centrally managed by the departments of woodpreservation and wood supply, who supply the users with well preserved wood. (4)Government should adopt a preferential and economically incentive policy for wood pres-ervation. For example, wood preservation charges are allowed to be added to the pro-duction cost.
