摘要
荒山造林地块交通不便,多为远山、高山和瘦山,立地条件较差,土壤瘠薄,不但是降水少、蒸发量大、日照时间短、负积温多,无霜期长,而且受干旱灾害频发,严重影响了造林的成活率低、保存率少.随着人们对生态环境的逐渐重视,荒山造林作为改善生态环境的重要手段也愈发得到相应的重视.借助荒山造林的方式既可以带动当地经济良好发展,同时可以有效改善环境质量,进而创设优质的生活环境.对此该文主要从适地适树原则、生态优先原则、混交原则以及稳定原则等方面分析了荒山造林树种选择的基本原则,同时阐述了造林树种的具体选择,并对荒山造林技术进行了探讨,以供参考.
Abstract
Arid and semi-arid mountainous areas,barren mountain afforestation plots are not convenient for transportation,mostly re-mote mountains,high mountains,thin mountains,poor site conditions,barren soil,but less precipitation,evaporation,short sunshine time,negative accumulated temperature,long frost-free period,and frequent drought disasters,seriously affected the survival rate of afforestation is low,low preservation rate.As people pay more and more attention to the ecological environment,afforestation of barren mountain as an important means to improve the ecological environment has been paid more and more attention.Afforestation of barren mountains can not only promote the good development of local economy,but also effectively improve the quality of the environment,so as to create a high-quality living environment.In this paper,the basic principles of tree species selection for barren mountain afforesta-tion are analyzed from the principles of land suitability,ecological priority,mixing and stability,and the specific selection of tree spe-cies for afforestation are expounded,and the afforestation technology of barren mountain is discussed for reference.
