青藏高原紫花针茅草原研究进展

On the Research Progress of Stipa purpurea Steppe in Qinghai-Tibetan Plateau

紫花针茅草原是青藏高原高寒草原中分布面积最大、最重要的群落类型。综述了紫花针茅草原研究的发展过程,分析讨论了一些热点领域和有价值的研究结果,总结出紫花针茅草原研究中存在的三个主要问题。(1)局部分散研究多,系统研究少;(2)特征研究多,机理研究少;(3)静态研究多,动态研究少。在此基础上,笔者认为紫花针茅草原退化及植被-环境互作机理是未来的研究重点,演替监测和群落演替趋势还需深入研究,进而增强对青藏高原紫花针茅草原群落特点和规律的理解,更好的为青藏高原的生态保护和生态系统科学管理提供基础资料。

Stipa purpurea steppe is the largest and most important community type in Qinghai-Tibetan plateau.The present paper reviewed the research progress,and summarized some hot areas and valuable results. Three main issues in the research of Stipa purpurea steppe were proposed in this review.（ 1） More partial dispersive studies,less systematic studies.（ 2） More characteristics studies,less mechanism studies.（ 3） More static studies,less dynamic studies. Reviewer proposed Stipa purpurea degradation and vegetation-environment interaction mechanism,which is the focus on future research,monitoring and community succession trends need further study. Only in this way,could the understanding of the characteristics and laws of Stipa purpurea community be enhanced in the Qinghai-Tibet Plateau and also better providing basic data for ecological protection and ecosystem scientific management of the Tibetan Plateau.
