To standardize the determination of urban spatial scope is an important basic work for scientific implementation of urban statistical monitoring, planning and construction, and for promoting the modernization of the national governance system and capacity

If you want to reasonably arrange the urban production, living and ecological space, you must first accurately grasp how big the city is and where it can be planned. According to the Ministry of Natural Resources, 683 urban areas have been determined for the first time in China, realizing the spatialization, quantification and precision of urban areas. At present, the results of urban area scope determination have been applied to land space monitoring and analysis, such as land space planning preparation and implementation monitoring, urban space monitoring and physical examination evaluation.

General Secretary Xi Jinping pointed out that "we should optimize the pattern of land and space development", "strictly control the boundaries of urban development, and promote the intensive and green development of urban space". Urban area is the basic spatial unit for observing the development and evolution trend of urbanization and studying urbanization. The cities in China have various distinctive forms, such as centralized, cluster and belt, and different natural conditions, such as rivers running through the city and stars and lakes densely distributed. It is of great significance to build a "ruler" that measures the urban area with objective standards. To standardize the determination of urban spatial scope is an important basic work for scientific implementation of urban statistical monitoring, planning and construction, and for promoting the modernization of the national governance system and capacity.

Only by promoting the quantification and precision of urban space can we scientifically plan economic construction and people's life. For example, after the establishment of Hebei Xiong'an New Area, there was no rush to build, but to promote the planning and preparation with high intensity, high density and high quality. With the help of advanced scientific and technological means, we integrated advanced concepts such as intelligent management, digital city, green and low-carbon, and planned every inch of land clearly before starting construction. The local people sighed: "It is a people's city to walk 5 minutes from the community to the kindergarten, 10 minutes to the primary school, 15 minutes to the middle school, and 300 meters to the park." The city is the place where all kinds of element resources and economic and social activities are most concentrated in China. The urban area achievement data and delimitation technology have strong follow-up expansion potential, further adding population, land, property rights Industry and other information can provide support for the planning and construction of a people centered urban environment suitable for employment, living, entertainment and tourism.

In recent years, a series of reform and development measures in land and space planning have led to the sustainable and healthy development of new-type urbanization with Chinese characteristics. Taking Xiamen City, Fujian Province as an example, the local government has drawn a "blueprint" for the integration of multi planning and multi planning in the whole spatial planning, integrated urban construction into the natural landscape pattern, promoted the simultaneous improvement of "economic output value" and "ecological beauty", and "blue sea and silver beach, clear water and green coast, blue sky and white clouds" became the golden card of the city. As an important basic information of the city, the urban area is included in the "Land Spatial Planning Map" information system, which lays an important foundation for promoting urban research and planning practice in line with China's national conditions, and will become a powerful technical tool for new urbanization strategic decision-making.

Cities are important carriers of modernization. To promote Chinese style modernization, we must grasp the "locomotive" of cities and scientifically plan the "growth coordinates" of cities. During his investigation in Beijing in 2014, General Secretary Xi Jinping once vividly compared the urban construction and development to "one can't 'step on the watermelon skin, where one slips'". General Secretary Xi Jinping proposed the coordinated development strategy of Beijing Tianjin Hebei with the goal of relieving Beijing's non capital function as the "cow's nose", and the whole country was fully revitalized. Based on the results of urban area determination, scientific planning of urban production, living and ecological space and improvement of urban governance will make urban life more convenient, comfortable and beautiful.
