摘　　要：我国沙棘属人工林植物发生大范围早衰甚至死亡现象,严重制约了其生态经济价值的发挥,已引起相关学者的广泛关注。本文综述了我国现有沙棘资源的分布情况,并对近年来我国沙棘属植物的更新复壮方式、抗逆性、海拔适应性等方面研究进展进行综述,明确我国沙棘属植物的生态适应性,提出了今后我国沙棘属植物的3个研究方向:(1)保护现有我国野生沙棘资源,建立完善的种质资源保存库;(2)加强隐蔽性强的致衰因子的相关研究;(3)考虑地理生态型的因素,将种源选择与优株选育相结合。通过以上研究为充分保护并利用现存的中国沙棘天然资源,合理地开展遗传改良,培育优质、高产及功能性的新品种提供参考。The phenomenon of premature decay and even death occurred in the Hippophae artificial forest seriously restricted the play of its ecological and economic value in China,which has attracted extensive attention of related scholars.In this paper,the distribution of existing Hippophae resources in China was reviewed,and the recent research progress in the regeneration pattern,stress resistance and altitude adaptability of Hippophae plants in China was reviewed,so as to clarify the ecological adaptability of Hippophae plants in China,and three research directions for Hippophae plants in China were proposed:(1)Protect the existing wild Hippophae resources and establish a perfect germplasm resource conservation bank;(2)Strengthen the related research of the hidden factors causing decay;(3)The factors of ecotype should be considered,and provenance selection and superior plant breeding should be combined.The above research provides reference for fully protecting and utilizing the existing natural resources of Hippophae,rationally carrying out genetic improvement and breeding new varieties with high quality,high yield and function.
