Generally speaking, many cities are distributed along the main traffic lines between urban agglomerations, which gather a large number of industries and populations, thus forming an economic belt  Strengthening economic belt planning and urban construction along the economic belt is an important aspect of building a modernized regional development system and promoting coordinated regional development  To this end, it is necessary to rely on important traffic arteries to gather economic factors, form a vertical or horizontal axis of economic development, and give full play to its role in coordinating regional coordinated development  For example, the coastal economic belt, the Yangtze River economic belt, the Longhailan new economic belt and the Beijing-Guangzhou-Beijing-Kazakhstan economic belt have gathered a large number of people and industries, and the distribution of cities is also relatively dense, forming a relatively obvious economic development axis, which has become the mainstay of economic development
