摘 要 ：我国50～60年代初期,林业部综合队曾编制红松(Pinus koraiensis Sieb.et Zucc.)、云杉(Picea spp.)、马尾松(Pinus massoniana Lamb.)、兴安落叶松(Larix gmelini(Rupr.)Rupr.)、白桦(Betula platyphylla Suk.)等树种材种出材量表。

Abstract:Timber assortment volume tables for Oak (Quercus mongolica Fisch et Frez.),hard hardwood and soft hardwood logs were established based on 498 Oak,437 hard hardwood and 576 soft hardwood standard trees cut down randomly.After properly dissected,volume I.B.,merchantable volume,dimension lumber volume,nondimension lumber volume,volume 0.B.,merchantable lapwood volume,lapwood O.B.,were calculated.3 or 4 nonlinear models were fitted to the data.The model with the closest correlation and minimum residual error was.selected for establishing the tables.With over 95% accuracy of both table compilation and application,the tables can be used in production.In Quanshan Forest Farm,1652 yuan and 206 working day per year were saved by the application of the timber assortment volume tables.
