摘　　要：本文以分布于我区各种生境的冷蒿居群为研究对象,从叶片形态结构特征及花粉形态特征等方面对其进行观察。研究结果表明:不同居群的冷蒿在形态及结构上都具有高光效、高利用水分的结构特点,也体现了抗旱、抗寒和抗强烈太阳辐射的能力,其形态结构与其所处的环境是相互协调统一的。冷蒿的花粉为长球形,表面纹饰为刺状纹饰,属于较为进化的类群;各生境冷蒿居群的冷蒿花粉形态没有明显变化。Morphological and structural characteristics of leaf and pollen of Artemisia frigida in different habitats of inner Mongolia were compared in this paper. The results showed that ： The Leaf structure and morphology of dfferent Artemisia frlgida populationc all had charalters with high light and water usage efficiency, in addition, they exhibited drought, cold and radiation resistance ability, these structure and morphology charactrors are in harmony wity their growth environment. The pollen morphology of Artemisia Frigidais long - sphericity, external sculpture is acanthaster, and belong to evolutive types. It has no obvious difference in the pollen morphology of Artemisia Frigida in different habitals.
