沙棘生态建设与开发中存在的问题与对策

The Practice and Thought about Ecological Resources Exploitation of Hippophae rhamnoides L.

沙棘是水保生态建设的先锋树种 ,沙棘果被确认为Vc之王、 2l世纪神果。丰宁是沙棘的适宜区 ,10多年来 ,依托密云、潘家口水库上游水土保持重点防治等项目 ,大力加强沙棘生态资源建设 ,取得显著成效。但因气候变异、持续干旱 ,沙棘造林成活率低 ,大面积沙棘林干枯死亡 ,沙棘果难以采摘 ,沙棘的加工、销售与产业化 ,均是影响沙棘生态资源建设的现实问题。本文根据多年的实践体会 。

Hippophae rhamnoides L. is known as one of the best species for ecological protection and against water and soil erosion.Its berries contain V C more than other plants.So it is called it a magic fruit in the 21 st century.Fengning County is an appropriate area for Hippophae rhamnoides L. growth.Over the past decade,as the projects for water Conservation carried out in the upstream Miyun of Panjiakou Reservoirs.Hippophae rhamnoides L. were afforested in a large area.As the result,ecological environment was protected and improved.However there are still many problems as low survival rate from changeable climate and dry weather,death of adult trees in a larger area because of difficulty of fruit picking,processing and marketing,etc.All these have affected Hippophae rhamnoides L. resources development and further improvement of ecological environment.In this paper,the discussion and solution are presented based on our practical experiences for years.
