摘要: 贺兰山位于内蒙古阿拉善高原和宁夏银川平原之间,油松林是该区重要的植被类型之一。针对贺兰山自然保护区天然油松林种群的分布特点,在封育区、旅游区和矿区分别选择有代表性的样地,以样地调查数据为依据,采用统计学方法对其种群结构和空间分布格局等进行研究。结果表明:不同样地的油松种群均处于稳定状态,且年龄结构基本相同,但是实生苗和幼树生长发育不良,种群呈现一定的衰退趋势,需要实施必要的人为抚育措施。由于生境中资源分配较均匀,不同油松种群在样地尺度上均表现为随机分布。

关键词: 贺兰山, 油松, 结构, 空间分布格局

Abstract: The pine forest is one of the typical vegetation types in the Helan Mountains which is situated on the eastern edge of the Alashan Plateau and the western edge of the Yinchuan Plain.Three representative sample plots were set up in different areas.The Pine population structures and distribution patterns were discussed by using statistical methods.The results showed that the population was in a stable state as a whole and the age structure of pine population in different sample plots were basically the same,but the population showed a declining tendency due to the bad growth of seedling and saplings .In addition,we also found that the Pine population in different sample plots showed random distribution pattern.

Key words: The Helan Mountains, Pinus tabulaeformis, structure, spatial distribution pattern
