摘　　要：草地蝗在新疆天山分布有古北种101种,占有绝对优势,占到天山蝗虫总种数的66.01%。在古北种中,又以中亚种占绝对优势,达63种。泛古北种33种,涉及5科,其中网翅蝗科有泛古北种15种,占天山泛古北种总数的的45.45%,所占比例最高。中亚种63种,涉及8科,其中斑翅蝗科有中亚种43种,占天山中亚种总数的68.25%,所占比例最高。在新疆天山仅分布有广布种1种,但特有种竟达51种,占到天山蝗虫总种数的33.33%。这是由新疆位于中亚大陆的中心,广布种难以交流和迁移,而这一独特的自然地理特征,却为特有种演化与形成创造了条件。There are 101 palaearctic species of grasshoppers on Tianshan mountains.the palaearctic species are absolutely dominant ones in this region,which account for 66.01% of total grasshoppers species.central-asia species are dominant ones among the palaearctic species,with 63 being.There are 33 Pan-palaearctic apecies belonged to 5 families,among this,Arcypteridae include 15 Pan-palaearctic apecies,with 45.45% among sum of Pan-palaearctic apecies,it is the highest proportion.central-asia species are 63,belonged to 8 families.Oedipodidae include 43 central-asia species,with 68.25% among sum of central-asia species,it is the highest proportion.Pan-distribution species 1 only,but endemic species are 51,with 33.33%.This is caused by these reasons,Xinjiang locates in the central of central-asia contient,Pan-distribution species is isolated,and this kind of geography just is the condition to form endemic species.
