摘要:

灌丛是贺兰山最主要的植被组分, 但关于该地区灌丛群落的专门研究并不多见。为了解该地区灌丛资源的分布及生长状况, 该研究对内蒙古贺兰山国家级自然保护区内主要的山地灌丛群落进行样方调查, 通过分析样方数据, 量化描述了各群落的基本特征。结果表明: 贺兰山自然保护区沿海拔梯度主要有准噶尔栒子群系(Form. Cotoneaster soongoricus)、紫丁香群系(Form. Syringa oblata)、小叶金露梅群系(Form. Potentilla parvifolia)、虎榛子群系(Form. Ostryopsis davidiana)、小叶忍冬群系(Form. Lonicera microphylla)、银露梅群系(Form. Potentilla glabra)、山生柳群系(Form. Salix oritrepha)和鬼箭锦鸡儿群系(Form. Caragana jubata) 8种主要的山地灌丛群系。

Abstract:
Scrubland is the most important vegetation component in Helan Mountains, Nei Mongol, but remians very poorly studied. In order to understand the distribution and growth status of the scrubland resources in this area, the shrub communities in the National Nature Reserve of Helan Mountains were sampled. Using the community data, the characteristics of the community structure were quantitatively analyzed. The results show that the shrub communities along an altitudinal gradient in the National Nature Reserve of Helan Mountains include the following formations: Form. Cotoneaster soongoricus, Form. Syringa oblata, Form. Potentilla parvifolia, Form. Ostryopsis davidiana, Form. Lonicera microphylla, Form. Potentilla glabra, Form. Salix oritrepha and Form. Caragana jubata. Furthermore, we also provide the data on species composition and structures of these montane shrub communities, which could provide insight for the conservation and management of these valuable communities.
