摘要
较全面的研究了内蒙古典型草原在不同放牧条件下的植物种类组成、生活型谱和种群特性及其生产力的变化，发现适度放牧下草原生产力具有补偿或超补偿性生产的现象，且草原植物多样性最高。
The experiments were conducted at Inner Mongolia Grassland
Ecosystem Research Station of Chinese Academy of Sciences. The results showed that there
were significant effects for grazing intenties to plant composition, life type and population
characteristics of range plants. Leymus chinensis and Stipa grandis steppes were converged
to Artemisia frigida under sustainable heavy grazing. The aboveground net primary
productivity and plant diversity index were maximum under moderate grazing. It means that
there is compensation or overcompensation for plant production.\=
