【摘要】 本文系统地分析了辽宁省章古台地区人工樟子松固沙林经营现状及枯死原因，对影响林分稳定性的各项因子进行了充分的论述，确定了评价林分稳定性指标；对现有固沙林的经营(间伐方式、适宜造林密度)提出了建议；提出了固沙林更新改造的方式方法。 首先根据几十年固沙造林经验及立地条件的不同，总结出章古台地区人工樟子松固沙林相对稳定的3种模式：林农复合模式、用材林型防护林模式、植被恢复模式，为适地适树、选地适树奠定了基础；其次，提出固沙林的改造方式；最后对章古台地区混交林营造技术进行了探讨，确定了与樟子松混交的适宜树种、混交方式以及具体的栽植技术。更多还原

【Abstract】 This article analyzed Pinus sylvestris var. mongolica sand-break management and the death in Zhanggutan area of Liaoning province systemically. Any reason, which influenced stability of trees, was discussed. This paper confirmed the standard of appraisement about the stability and gave the advice about plantation for sand fixation.First, accounting to the sand-control and plantation experiences and different conditions, the article sum up three modes of Scotch Pine sand-break in Zhanggutan area: forest and farming complex mode, lumber using shelterbelt forest, vegetation recovering mode. At the same time, growth and soil benefit of Pinus sylvestris var. mongolica were analyzing. At last, the planting technology of mixing forest was discussed in Zhanggutan area. The fitting trees, mixing mode and planting technology were ensured.更多还原
