沙棘作为先锋树种之一,在我国乃至其它国家和地区的受损、濒危的生境系统的修复、治理和防治水土流失中的作用,已被世人所公认。我国20年来大规模地种植沙棘,不仅有了明显的生态和社会效益,更带动了经济多元化的发展,成绩是巨大的。但是,目前沙棘存在的问题,如老林分的死亡,连续几年结果后基本上不再见果,病虫害严重,木蠹蛾成灾,林分衰退与复壮管理,生态造林技术规范,沙棘生态工程建设,沙棘育种指标等的确定,都还存在着不少棘手、或模糊不清的问题,亟待认识、研究和解决。今在本刊连续发表的“论先锋植物沙棘”几个姊妹篇文章,是该研究小组在总结他们20年来的研究实践,并借鉴他人成果,将较系统的从’双重生态型’概念出发,以一个新的视角来试图阐释沙棘,提出一些理论概念、观点和方法,愿与同事们讨论与商榷,使沙棘的研究与应用步入一个新水平。本刊编辑部欢迎有关学科和沙棘界的专家、同仁和领导们,一起来总结我们走过的20年历程,各抒己见,百家争鸣,从理论和实践中提高对沙棘的全面认知水平,促进沙棘事业的健康快速发展和壮大。
Seabuckthorn, as one of the pioneer tree species, has been recognized by the world for its role in the restoration and management of damaged and endangered habitats in China and other countries and regions. Seabuckthorn planting on a large scale in the past 20 years has not only brought obvious ecological and social benefits but also boosted the diversification of economy. The achievements are enormous. However, the existing problems of seabuckthorn, such as the death of the old forest, basically no longer see fruit after several years of results, serious pests and diseases, the disaster of timber moth, the recession and rejuvenation management of forest, the technical specifications of ecological afforestation, the ecological engineering construction of seabuckthorn , Seabuckthorn breeding indicators, etc., there are still many problems, or ambiguous, urgent understanding, research and solution. Several articles in this series, entitled “Pioneer Seabuckthorn”, are published by this research group. After summarizing their research practice for 20 years and drawing on the achievements of others, the research team systematically researches the concept of ’double ecotypes’ Starting from a new perspective to try to interpret seabuckthorn, put forward some theoretical concepts, views and methods, is willing to discuss and discuss with colleagues, so that the research and application of seabuckthorn into a new level. Our editorial department welcomes the relevant disciplines and seabuckthorn industry experts, colleagues and leaders together to sum up the 20 years we have traveled, to express their views, a hundred schools of thought, from theory and practice to improve the comprehensive understanding of seabuckthorn and promote the cause of sea buckthorn The rapid and healthy development and growth.
