通过对大黄山区森林资源破坏到恢复几个阶段的分析,在对该区造林树种的适应性选择、水保措施整地、灌木林利用等方面研究的基础上,论述了该区退耕还林主栽品种和特殊整地方式及种植模式,估算了退耕还林实施2年来造林10 000hm2将产生的生态效益和经济效益,为进一步对该区乔灌林封育、改造和利用提出了建议和对策。本文研究结果可为祁连山区相近造林立地条件的生态环境建设提供参考。
Based on the analysis of several stages of the destruction and restoration of forest resources in the area of Huanghuang Mountain, based on the researches on the adaptive selection of afforestation tree species, site preparation of soil and water conservation measures and the utilization of shrubbery, Planting varieties and special land preparation methods and planting modes. The ecological and economic benefits from afforestation of 10 000 hm2 in the past two years after the conversion of cropland to forestry are estimated. Suggestions and measures are put forward to further improve the enclosure, transformation and utilization of the trees. The results of this paper can provide reference for the ecological environment construction of similar afforestation sites in Qilian Mountains.
