澳大利亚树木工业利用的若干情况

SOME ASPECTS OF THE INDUSTRIAL USE OF AUSTRALIAN TREES

The properties of the woods and barks of eucalyptus and Australian acacias differ between themselves and from the softwoods common in the northern hemisphere. Over many years an understanding of these differences has been developed as well as the way different properties may be controlled. This has led to the widespread use of the wood of certain species as a source of building materials and of fibre for pulp, not only in Australia but increasingly in other countries. For some uses, the wood or bark of certain eucalyptus and acacia species are preferred to those of any other species. Examples of the technological developments which have enabled the increased use of their woods are given. Attention is directed to the need when establishing plantations to select the species which satisfy not only forestry requirements but particularly end-use requirements to ensure maximum productivity from available land.
