摘要
通过测定阿拉尔地区胡杨相同叶形及不同叶形的叶片叶脉的分形特征,对胡杨叶片的分形特征进行了研究。结果表明:胡杨叶片存在柳形、卵状菱形和鸡爪形等3种叶形;同一株胡杨相同叶形的成熟未老叶片在统计意义上具有相似的分形特征;同一株胡杨不同叶形的成熟未老叶片的分形特征不同。
Fractal characteristics of the leaf veins of Populus euphratica with the same shape and different-shaped leaves in Alar region were determined.Fractal characteristics of Populus euphratica were studied.Result shows that the leaves of Populuseuphratica have three leaf shapes (willow shape,rhombus shape &chicken claw shape);matured leaves of the same Populuseuphratica with same leaf shape have similar fractal characteristics in the statis-tical sense.Fractal characteristics of the same strains of Populuseuphratica with different leaf shapes are different.
