Urban built-up area refers to the area that has been developed and has municipal utilities and public facilities infrastructure. The speed of a city's development can be reflected by the built-up area. Among China's first-tier cities, such as Beijing, Shanghai, Guangzhou, Shenzhen, etc., their built-up areas have exceeded 1,000 square kilometers. Today, however, we are going to focus on the urban built-up area of the three northeastern provinces.
According to the ranking of the top 100 cities in terms of built-up area in China, some cities in the three northeastern provinces have been successfully selected for this list. The first is the city of Shenyang, with a built-up area of 567 square kilometers, ranking 16th in the country. It is followed by Changchun City, with a built-up area of 54271 square kilometers, ranking 17th in the country. The city of Harbin again, with a built-up area of 44575 square kilometers, ranking 22nd in the country. In addition, the city of Dalian (built-up area 44404 square kilometers) ranked 23rd in the country, and Daqing City (built-up area of 25005 square kilometers) ranked 44th in the country, and Jilin City (built-up area of 19342 square kilometers) ranks 59th in the country, Yingkou City (built-up area of 18007 square kilometers) ranked 65th in the country, and Anshan City (built-up area of 17502 square kilometers) ranked 69th in the country, and Fushun City (built-up area of 14182 square kilometers) ranked 95th in the country.
The selection of these cities means that they have made certain achievements in urban development. But we also note that many of the smaller cities in the Northeast also have relatively large built-up areas. For example, the city of Qiqihar in Heilongjiang (built-up area of 12746 square kilometers), Benxi City in Liaoning Province (built-up area of 109 square kilometers), Panjin City (built-up area of 10689 square kilometers), Liaoyang City (built-up area 10244 square kilometers) and so on. And some relatively small cities, such as Yichun in Heilongjiang (built-up area of 9721 square kilometers), Jiamusi City (built-up area 961 square kilometer), Huludao City, Liaoning Province (built-up area 946 square kilometers), Jixi City in Heilongjiang (built-up area of 80 square kilometers), etc., the built-up area is smaller.
From the above data, we can see that there are large differences in the urban built-up area of the three northeastern provinces. As an oil city, Daqing City has a built-up area of 25055 square kilometers, second only to the provincial capital Harbin, ranking first in the province. It is worth mentioning that the built-up area of Daqing City exceeds that of Qiqihar City, the second largest city in Heilongjiang, showing its outstanding performance in urbanization development. In addition, Panjin City, the smallest city in Liaoning Province, has a built-up area of 106 square kilometers. While Yingkou City surpassed Anshan City, it also showed a good momentum of development.
The difference in the area of urban built-up area can reflect the difference in the level of urban development and economic status from different perspectives. The built-up area of Daqing City exceeds that of Qiqihar City, which means that Daqing has a higher development speed and potential in terms of urbanization. The built-up area of Yingkou City exceeds that of Anshan City, which also shows the enthusiasm and innovation ability of Yingkou City in urban planning and development. The development of these cities is not only of great significance to the region, but also has a positive impact on the economic development of the entire Northeast region.
However, it should also be noted that the built-up area of an urban area is only a partial indicator of urban development, and the whole picture of urban development cannot be inferred from this area alone. The growth of urban built-up area may bring some negative effects on the environment, such as the consumption of land resources and the destruction of the ecological environment. Therefore, in the process of urban development, we should also pay attention to the sustainable development of the city and protect the natural environment and ecosystem.
For cities with small built-up areas, we can think about how to increase the speed and potential of their urban development. Does this mean that these cities have certain limitations in terms of economic development? Are there some underlying reasons for the limitations of urban built-up area? For example, do factors such as geographical location, historical legacies, and policies have had a significant impact on urban development? It is hoped that more research will focus on this issue in the future and provide more scientific guidance and strategies for urban development.
In summary, there is a large difference in the area of urban built-up area among the three provinces in Northeast China, which reflects the difference in urban development level and economic status. The built-up area is only an indicator of one aspect, and it cannot fully represent the whole picture of a city. Urban development needs to focus on sustainable development and ecological environmental protection. For cities with small built-up areas, we need to go deep into the reasons behind the problem and provide solutions accordingly. Only in this way can we achieve sustainable urban development and harmonious coexistence between man and nature.
