通过对裕民县和布尔津县野扁桃分布区的物种组成及群落结构调查,分析其植物区系特点及物种多样性特征。结果显示,野扁桃分布区的植物区系组成都以北温带成分占优势,温带属性是野扁桃分布区植物区系的基本特点;两地植物群落以野扁桃为主形成群落,但群落结构组成不同,表明生境和物种适应性间存在差异;两地群落物种多样性在物种丰富度、多样性指数及均匀度等多样性指数上均表现出草本层>灌木层的规律。
Through the investigation of species composition and community structure of Yam Almond in Yumin County and Burqin County, the characteristics of flora and species diversity were analyzed. The results showed that the flora of Yeh Tientsin is dominated by the north temperate component, and the temperate zone is the basic characteristic of the flora of Yeh Tientsin. The two communities are dominated by Yehliu, but the community structure Which indicated that there was a difference between habitat and species adaptability. Species diversity of the two communities showed the law of herb layer> shrub layer on diversity indices such as species richness, diversity index and evenness.
