黄土高原砒砂岩区河岸带沙棘林营造与管护技术的研究

黄土高原砒砂岩区立地条件恶劣,河岸带是该地区具有特殊生态功能的组成部分,在河岸带种植沙棘Hippophae rhamnoides对于改善当地生态环境具有理论和现实的意义。总结几年来在该地营造与管护沙棘林的研究成果与实践经验,能够更好地为实施植被措施改善恶劣地区的生态环境奠定理论和实践基础。具体总结为:因地制宜,科学布设;选择良种壮苗,确保成活率;选择合理季节,抢墒保墒种植;保持苗木活力,搞好假植和保护;认真整地种植,确保造林质量;搞好抚育管理,保证可持续发展。同时对存在的生物多样性、林分抚育管理、病虫害防治问题进行了探讨。

Research on the technology of silviculture and protection of seabuckthorn forest in riparian zone of arsenic rock zone on the Loess Plateau

The site condition of arsenic rock zone on the Loess Plateau is very atrocious.Riparian zone is a special part with ecological functions in the region.It has theoretical and practical meaning to improve local ecological environment to plant seabuckthorn in riparian zone.To summarize the research achievements and practical experience of silviculture and protection of seabuckthorn forest in the area could establish the theoretical and practical foundation for improving the ecological environment of atrocious areas by practicing vegetation measure.They could be concretely summarized as follows: adjust measures to local conditions;design and allocate scientifically;select well-bred and strong seedling to insure surviving rate;choose reasonable seasons for planting in good water condition;keeping good livingness of seedlings and preplanting and protection;carefully prepare afforestation to guarantee the quality of planting;foster and manage scientifically to ensure sustainable development.The existing problems such as biodiversity,foster and manage,as well as insects control were discussed at the same time.
