Endanger factors and protection countermeasure of rare and endangered plants of Liupan Mountain Natural Reserve

采用样地调查与样线调查相结合的方法,对六盘山国家级自然保护区珍稀濒危植物资源状况进行了调查研究.通过野外调查、监测与繁育相结合的方法,研究六盘山境内天然分布的国家珍稀濒危植物种类的生态学习性、生物学特性,及其致濒原因.结果表明,六盘山国家级自然保护区境内分布的珍稀濒危植物共有20科30属37种,导致其濒危的主要原因是人为因素、植物本身的繁殖特性、生境变化等,提出拯救保护措施,从而为宁夏合理开发利用珍稀濒危植物资源奠定理论基础,为生物多样性监测和预警体系的建立,应对生物多样性保护方面存在的各种问题提供科学依据.

Using the combination of sample plot survey and line transect method in Liupan Mountain National Nature Reserve Area of rare, the endangered plants resources were investigated in this study. Through the combination of field investigation, monitoring and breeding method, Liupan Mountain research within the territory of the distribution of national rare and endangered plant kinds of ecological learning, biological characteristics and causes. The results showed that the Liupan Mountain National Nature Reserve within the area of distribution of the rare and endangered plant a total of 20 families and 31 genera and 37 species, leading to its endangered reasons is the human factor, plant reproductive characteristics,habitat change, proposed rescue protection measures, so as to the rational development and utilization of resources of rare and endangered plants lay the theoretical foundation and for biodiversity monitoring and early warning system is established,to address the biodiversity protection in the presence of various problems provide scientific basis.
