剌槐(Robiaia Pseudoacaeia)是我区山区主要造林树种之一,据最近森林资源清查,7个山区县共有剌槐林183558亩,按海拔高度分中山21268亩,低山56618亩,丘陵105672亩。这些剌槐林对保持水土,涵养水源,解决民用材及烧柴等起到一定作用。但是由于立地条件差,加之管理不善,致使大部分刺槐林枯梢严重,树皮发黑,林相残破。因此,研究探讨这种残、疏剌槐林适宜的更新技术,以发挥其多种生态和经济效益,就成了亟待解决的问题。我们在阜平县驼梁山林场进行了残、疏林皆伐更新试验。
According to the recent inventory of forest resources, there are 183558 mu of acacia forest in the seven mountain counties. According to the altitude, 21268 mu of Zhongshan are divided into 56618 mu of low mountain and 105672 mu of hills. These acacia forests play a role in maintaining soil and water, conserving water sources, solving civilian materials and burning firewood. However, due to poor site conditions and mismanagement, most of the black locust trees were severely wounded, the bark was black and the forest was shattered. Therefore, it is an urgent issue to study and discuss the appropriate renewal technology of this residue and sparse locust to develop its multiple ecological and economic benefits. We carried out in Fuping County Tuoliangshan forest residues, sparse clearing research.
