摘要
阐述了铁路防护林的作用和意义,并对广西铁路防护林现状进行分析。指出广西铁路沿线防护林存在林种结构单一、种植不规范、断带现象严重、造林水平低、防护林总量少等问题。提出应逐步改造现有林木、因地制宜选择造林树种、丰富植物群落结构、采用快生树种与慢生树种相结合的造林方式、提高造林水平、加强监督管理等发展对策。
The present study elaborates the function and significance of shelter forest along railway sides and analyzes its current status in Guangxi. During survey of the existing forest, several problems were found such as single forest structure, non-standard planting, discontinuous forest belts, low forestation level, less shelter forests, etc. According to the existing problems, some suggestions have been made such as rehabbing existing forests step by step, selection of forestation species according to local conditions, enriching plant community structure, planting fast-growing species combined with slow-growing species, improving forestation level, proper supervision and management, etc.
