昭乌达盟各地,生长着品种繁多的灌木。过去,人们对发展灌木很少重视,时至今日,还有人一提到造林,只对乔木感兴趣,导致不适于栽乔木的地方也栽乔木。其结果是造的多,活的少,保存的更少。昭乌达盟位于燕山山系七老图支脉,地貌复杂,山脉交织,沟壑纵横,西部海拔最高达2,067米,东部海拔最低不足300米。气候干旱少雨,风沙大,土壤也较贫瘠。全盟有宜林地4,000万亩,森林覆被率只有16.6％。到1990年要把所有的宜林地绿化起来,任务是很艰巨的。然而,昭盟8万多平方公里土地上,到处都生长着紫穗槐、胡枝子、小时锦鸡儿、沙棘、荆条、黄柳、山杏、山枣、榛子等灌木。因此,昭盟地区的造林,必须从发展灌木上寻找出路。 Zhaowuda League around, growing a wide variety of shrubs. In the past, people paid little attention to the development of shrubs. Up till now, others have mentioned that afforestation is only interested in trees and trees are not suitable for planting trees. The result is more, less live, less preserved. Zhaowuda League is located in the Yanshan Mountains seven old map branch, complex landscape, intertwined mountains, ravines aspect, the highest elevation of 2,067 meters in the west, the eastern elevation of less than 300 meters. Arid climate, the climate is big, the soil is also more barren. The alliance should have a forest of 40 million mu and a forest cover rate of only 16.6%. It is a daunting task to green all the forests by 1990. However, Zhao League more than 80,000 square kilometers of land, growing everywhere Amorpha fruticosa, Lespedeza, Caragana, Seabuckthorn, Vitex, yellow willow, apricot, mountain dates, hazelnuts and other shrubs. Therefore, afforestation in the Zhao League area must find a way out from developing shrubs.
