The results were as follows: ①The urban spatial connection of Guanzhong urban agglomeration showed Xi’an - Baoji“double center - radiation”pattern overall. On the part,the spatial connection patterns of“sector,radial”shapes were developed. ②Guanzhong urban agglomeration was at a low developmental level,and it was with extreme concentration and imbalance.The eastern towns had stronger influence on the urban agglomeration network than the western towns. ③Guanzhon
