高山草地植物种群生态适应对策系列研究 Ⅳ天祝高山草地植物种群生态适应对策形成机制
Biomass measurements were collected from 32 plant species in Tianzhu alpine grassland to establish a mathematical model for an analysis of the ecological adaptability of plant populations.
数学模型分析草地参试植物的生态适应评判值和种群与环境相互作用系数，划分出趋活（占总调查的３１％，下同）、趋中（４４％）和趋惰（２５％）３种生态适应性，它们构成了高山草地植物种群的生态适应对策。
