摘　　要：中小规模沙被受到的关注较少,研究的文献也不多。文章利用遥感手段结合实地考察对巴彦淖尔市境内的中小规模沙被进行了普查和命名,结果表明:中小规模沙被分布广泛、数量众多。同时从中小规模沙被生态系统的特征、重要性、易损性和保护意义等方面进行了研究和论述,以促进对中小规模沙被的深入了解以及对中小规模沙被生态系统研究与保护必要性的认识。另外,针对沙被生态建设需求,提出了用于衡量一个区域或生态系统与原生状态相似或接近程度的原生度,以及生态建设应该尊重自然规律和坚持高原生度的原则。Due to less attention, few articles touched upon small and medium sand covers. Through taking a census of the small and medium scale sand covers in Bayannur City by using remote sensing technology and field detection, it makes us realize that the small and medium-sized sand is widely distributed and numerous. Furthermore, the article discusses the importance of small and medium scale sand covers such as diversity, indicator, sensitivity, vulnerability, characteristics and protection, in order to promote understanding the necessity to research and protect the ecosystem of the small and medium scale sand covers. Besides, for the needs of ecological construction of sand cover, this paper also proposes the native degrees, used to measure the similarity degree of an area or ecosystem to its original status. And we also proposes that ecological construction should respect the natural law and adhere to the principle of plateau fertility.
