天祝高山草地植物种群生态适应对策组成

A Series of Studies on Ecological Adaptive Strategy of Alpine Plant Populations: Ⅰ Composition of Ecological Adaptive Strategy in Tianzhu Alpine Grassland

对甘肃天祝高山牧地和休闲牧地中３２个植物种群进行了６种生境、２５个处理、全年４次测定、２次重复的生态适应性野外天然和水、肥干扰草地样方中的生物量调查。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。

The morphological characteristics of four dominant plant species from Tianzhu alpine grassland were studied under both field and controlled artificial climatic conditions. The ecological adaptability of the plants was analysed by establishing relationships between environmental disturbances and plant phenotypes.
