摘要: 本文描述了门源县的高寒草甸生态系统的主要成分与其结构特征及它们同营养结构、垂直结构、水平格式之间的生态学的依赖关系,以及形成这种关系的内在和外部的因素。由于高寒草甸生态系统是属于低生产力的矮草型的植物生物群落,所以它是一种低功效的生态系统。之所以成为这种类型的生态系统,主要是适应高寒临界物理环境的后果。由于人们的经济活动和虫害、鼠害的破坏,已经而且还在继续破坏生态系统中的生态学平衡。我们已对产生这些因素的某些原因进行了分析。这些原因可为高寒草甸系统的合理利用,保护和改良提供理论基础。

Abstract: The paper describes the main components and their structural characteristics in the ecosystem of alpine meadow and their ecological dependent correlation between the trophic structure, vertical structure, horizontal pattern and the intrinsic and extrinsic-factors forming this ecological dependent correlation. The ecosystem of alpine meadow is one in low functional efficiency due to the phytobiocenose belonging to the short-grass type of low productivity. This type is result adapting the alpine critical physical conditions. The ecological balance of ecosystem has been destroying from the economic activities of mankind and the destruction of pest-insects and pestrodents. Furthermore, we have analyse some reasons producting these factors which will provide with the theoretical base for the rational utilization, protection and improvement of the ecosystem of alpine meadow.
