围场自治县位于河北省最北部,是全省重点林区之一。多年来在突出抓好宜林荒山绿化、防护用材林基地建设的同时,把重点放在侵蚀沟、冲积和河道的治理上。把沙棘做为综合治理和山区综合开发的重要树种。现沙棘造林面积已达到2.67万hm~2,有1.33万hm~2开花结实,年产沙棘果100万kg。由于大力发展沙棘,不仅改善了本地区生态环境,而且为发展绿色产业奠定了基础。其主要做法是:1.认识沙棘价值,制定发展规划。沙棘是当地乡土树种,天然分布很广,但由于过去对沙棘价值缺乏认识,任其毁林开荒,资源遭到严重破坏,致使水土流失加剧,风沙灾害频繁.县委县政府经过组织专家进行调查后,制定了《农业基础建设十年规划指导纲要》和《10120沙棘林工程规划》。从1990年开始,10年完成8万hm~2 (120万亩)造林任务;2.加强舆论宣传,建立育苗基地。由于采取得力措施,确保每年育沙棘苗33hm~2,提供合格苗木5000万株;3.总结治理模式,实行典型带动,即护坡护堤、乔灌混交和生物围栏3种沙棘造林模式。
Yard Autonomous County is located in the northern part of Hebei Province, is one of the key forest areas in the province. Over the years, while giving prominence to the afforestation of afforested forests and the construction of protective timber forest base, the emphasis should be placed on the management of erosion ditches, alluvial and river courses. Seabuckthorn as a comprehensive management and comprehensive development of mountain species. Seabuckthorn afforestation area now has reached 26700 hm ~ 2, with 13300 hm ~ 2 flowering strong, with an annual output of 1000000 kg of sea buckthorn. Since the development of seabuckthorn, not only to improve the ecological environment in the region, but also laid the foundation for the development of green industry. The main approach is: 1. Recognize the value of seabuckthorn, the development of development planning. Seabuckthorn is a native tree species with a wide natural distribution. However, due to the lack of understanding of the value of seabuckthorn in the past and the deforestation and land reclamation, the resources have been severely damaged, resulting in increased soil erosion and frequent sandstorms. After investigation by county experts , Formulated the “Outline of Guiding Outline of Decade of Agricultural Infrastructure Planning” and “10120 Seabuckthorn Forest Project Planning”. From 1990 onwards, 10 million years to complete 80,000 hm ~ 2 (120 million mu) afforestation tasks; 2 to strengthen publicity media, the establishment of nursery base. As a result of effective measures to ensure that the annual sand-raising thorns seedlings 33hm ~ 2, providing qualified seedlings 50 million; 3. Summarize the governance model, the implementation of a typical lead, that is, slope protection berm, mixed blessing and biological fencing three kinds of seabuckthorn afforestation mode.
