摘要
沙地云杉为内蒙古特有树种,干旱适应性强,已成为我国西部重要造林树种。在长期适应干旱生态条件的过程中沙地云杉形成了紫果型、绿果型和红果型等多种生态型。文章对各种生态型沙地云杉的表观性状分化进行了比较研究,可为沙地云杉生态型分化机理研究提供理论参考,对扩大沙地云杉造林面积和西部大开发的生态环境建设具有重要的指导意义。
Picea mongolica is an endemic tree species in Inner Mongolia Autonomous Region, Chna, It is an important afforestation tree species in the west of China due to its drought adapting to drought environment for a long time,. Comparative studies on differentiation of apparent properties of the three ecotypes Picea mongolica werer carried out in this paper. The results can supply theoforest area and ecological environment construction in development of West China.
