刺槐(Robinia pseudoacacia Linn.)生长迅速,适应性强,耐干旱瘠薄,根系发达,凋落物易分解,具有保持水土和改良土壤的作用,是我省渭北黄土高原主要造林树种之一。自1958年以来,国营林场和社队林场营造的刺槐林,保存面积达100多万亩。有的进入成熟期,开始采伐利用,大部分处于中龄和幼龄阶段。为了测算刺槐林的蓄积量,生长量,以及经营管理的需要,我们于1981年8月至1982年5月在崛山、野河、槐坪、英烈,柳林、北辛庄六个林场进行标准地调查,伐取样木、编制刺槐二元材积表。
Robinia pseudoacacia Linn. Is one of the main afforestation species in the Loess Plateau of Weibei, China. It grows rapidly, adapts well, is drought-resistant and infertile, its root system is developed and its litter is easily decomposed. It has the functions of soil and soil conservation. Since 1958, the state-owned forest farms and social-forestry centers have created more than 100 million mu of acacia forests. Some entered maturity, began cutting use, most of them in the middle-aged and young stage. In order to estimate the stock volume, growth and the management needs of Robinia pseudoacacia, we conducted six forest farms in Wushan, Yehe, Liuping and Beixinzhuang between August 1981 and May 1982 Standard survey, cutting wood sampling, preparation of acacia binary volume table.
