摘　　要：采用野外实地形态观察、人工气候箱内不同光、温处理的方法，对甘肃天祝高山草地４个建群种的微观形态、超微结构进行了观察，并对各种形态联系生态适应对策进行了内、外部形态表征。结果表明，环境因子不同量的干扰是形成生态适应对策表征的外动力。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.
