解决小径材的利用问题是欧洲各国的当前任务。在许多国家内,由于用煤、石油和瓦斯代替了薪材,小径材的需要量减少。在煤矿工业上,因为有更便宜的材料代用,木材的需要量也同样缩小。1959年欧洲小径材总采伐量为1.76亿立方米。欧洲的总采伐量预计将从1955年的2.96亿立方米增加到1970年的3.28亿立方米。按照远景规划资料,到1970 The solution to the problem of using small diameter timber is the current task of all European countries. In many countries, the demand for small-diameter timber is reduced by the replacement of fuelwood with coal, oil and gas. In the coal mining industry, the demand for wood is similarly reduced because of the substitution of cheaper materials. In 1959, the total volume of cuttings in Europe was 176 million cubic meters. The total volume of harvest in Europe is projected to increase from 296 million cubic meters in 1955 to 328 million cubic meters in 1970. According to the long-term planning information, to 1970
