| 摘 要： | 本文根据鸟类的形态、生态及地理分布的特征,应用模糊数学方法对行(行鸟)形目、鸽形目、沙鸡类三者的亲缘关系进行了初步探讨。结果表明,沙鸡类相对鸽形目而言更接近(行鸟)形目。沙鸡类应作为(行鸟)形目的一个科。

| Abstract: | The pterocletes are birds of the arid regions of Africa,Asia,and Southern
Europe.Their relationships to the Columbiformes and the Charadriiformes have
been debated for more than a century.
Our new approach has been to determine some fuzzy matrix of pterocletes,
Charadriiformes and Columbiformes,to calculate most approachability degree of
pterocletes as against Charadriiformes and Columbiformes.
The results are quite clear:The Pterocletes are the sister group of a large
part of the order Charadriiformes and are closer to the Charadriiformes than they
are to the Columbiformes. |
