丰宁满族自治县位于河北省承德市西北部燕山北麓,内蒙古高原南缘山坝地区,风沙侵蚀是造成这个县水土流失较为严重的主要原因之一,全县沙化面积0.67万hm~2。风沙侵蚀区内虽经解放后大规模的植树造林,防风固沙,实施小流域重点治理等水土保持措施,但植树成活率低、效果差的问题始终存在于这些风沙侵蚀区。1997年春夏,县水利水保局工程技术人员采用塑料薄膜容器栽植的方法,在海河水利委员会租赁的沙棘开发基地实施沙棘造林,取得了成活率达97％的显著效果。
Fengning Manchu Autonomous County is located in the northern foot of Yanshan, northwest of Chengde City, Hebei Province, Shanba region in the southern edge of Inner Mongolia Plateau. Wind erosion and sand erosion are one of the major causes of soil erosion in this county. The desertification area of the county is 6,700 ha. Although the large-scale tree planting and afforestation in wind-blown sand area after emancipation, windbreak and sand-fixation, and implementation of water and soil conservation measures such as key control of small watershed, the problems of low tree survival rate and poor effect are always present in these aeolian-sand erosion areas. Spring and summer 1997, county water conservancy and hydropower Bureau engineering and technical personnel using plastic film container planting method, in Haihe River Water Resources Commission leased seabuckthorn development base implementation of sea buckthorn afforestation, achieved a survival rate of 97% of the remarkable effect.
