4 City (town) status quo characteristics
(1) hierarchical characteristics of cities (towns): According to administrative divisions and the actual functions of cities (towns), cities (towns) are divided into four levels: urban area, central town, ordinary town and market town. Central towns include: Hexi, Baiya, Laoguan, Siyi and Shuiguan.
(2) Characteristics of city (town) scale: The average population of the city (town) is 0.3 1.000, and the average size of 45 cities (towns) except three urban offices and Jiangnan Town is 0.23 million. The population of central cities accounts for 69.20% of the population of all cities (towns). Other large-scale towns include Baiya (0.6 million), Hexi (0.59 million), Laoguan (0.54 million), Siyi (0.46 million) and Hongshan (0.55 million), and the rest are mostly 0. 1-0.
(3) Functional characteristics of the city (town): the function of the city (town) center is clear, the urban area is the political, economic, cultural and transportation center of the city, and the central town serves 2-5 townships as the center of the district. Ordinary cities (towns) are the political, economic, cultural and transportation centers of their own townships.
From the perspective of economic function, the functions of cities (towns) in the whole city are relatively simple, with a small number of farmers' tourism types (urban area, Laoguan town and Tiangong township), and the rest cities (towns) with agricultural and sideline products processing and fair trade functions are mostly farmers' cities (towns).
(4) Distribution characteristics of cities (towns): The distribution of cities (towns) in the whole city is mainly along the Yangtze River, national highways and provincial highways, with 2 12 national highways as the main axis. Among them, Pingba towns along the Yangtze River are dense and have good development conditions. Compared with the east and west sides of Jialing River, there are more towns in the southwest and smaller in scale, while there are more towns in the northeast and smaller in scale.
The density of a city (town) is 8 1.6 km2/ town, with an average service radius of 5.02km and an average service population of 1.65 million.
Analysis on the present situation and characteristics of spatial structure of five cities (towns)
(1) Most cities (towns) are concentrated along the traffic trunk lines.
At present, among the 46 townships, 5 townships are located in 2 12 national highway, 10 township is located in 302 provincial highway, and 4 townships are located in the three main traffic trunk lines of Langyi county highway, which has obvious axial development characteristics.
(2) Cities (towns) are generally concentrated in dam areas and hilly areas, and the distribution is relatively uniform.
Except for three offices in urban areas and Jiangnan town, the other 46 cities (towns) are all located in hilly areas, and the average distance between cities (towns) is about 6- 15km.
(3) The horizontal connection between towns is not close.
At present, most cities (towns) in the city are closely connected with the central cities, and the horizontal organic connection between cities (towns) is not enough, the division of functions is not clear, and the production cooperation relationship is not strong.
6 City (town) grade scale status and characteristics analysis
(1) At present, the population size and rank sequence of cities (towns) are distributed for the first time, and the urban population of central cities accounts for 72.23% of the urban population, indicating that the agglomeration of central cities is greater than diffusion and is in the stage of agglomeration growth.
(2) The scale of cities (towns) is generally small, mostly less than 5,000 people, and most of them are in the stage of natural growth and development of agricultural society, and their scale agglomeration ability is low.
(3) The lack of towns with a population of 1-65438+ 10,000 shows that there are very few sub-central towns in Langzhong except the central city.
Based on the above analysis, it can be seen that the urban system in Langzhong is still in the "single core system" stage of five development stages: "weak core system-single core system-single core multi-core system-multi-core system-strong core system".
7. Analysis of the present situation and characteristics of urban (town) functional combination
From the historical evolution of Langzhong Town, it mainly includes three types:
(1) A farmer town established and gradually developed by rural fair trade. Most towns and villages in Langzhong belong to this category.
(2) Commercial towns with developed commodity trading, such as Hexi, Wencheng, Ssangyong and Pengcheng, are located in rivers or traffic arteries, with convenient land and water.
(3) Because of its good tourism resources, it has gradually developed into a major tourist town, such as Jiangnan and Laoguan.
The function of Langzhong town is mainly influenced by the economic development mode and regional resources, and its function is relatively simple, and the division of functions has not yet formed its own characteristics and lacks agglomeration effect.
