China News Service, Beijing, August 14 (Reporter Sun Zifa) China's famous population density dividing line "Aihui (Aigun)-Tengchong" line (proposed by Chinese geographer Hu Huanyong in 1935, also known as "Hu Huanyong Line") It is also a typical demarcation line of unbalanced and insufficient development in the eastern and western regions of China, and has attracted much attention for a long time.

　　The 2nd "Beautiful China Middle Ridge Belt" Sustainable Development Forum hosted by UNESCO International Center for Natural and Cultural Heritage Space Technology (HIST) and International Center for Sustainable Development Big Data (CBAS), August 12 to On the 13th, it was held in Aihui District, Heihe City, the northern starting point of the "Hu Huanyong Line".

Guo Huadong, academician of the Chinese Academy of Sciences (CAS), director of HIST and CBAS, and leader of the "Big Earth Data Science Project" pilot project of the Chinese Academy of Sciences, gave a special report on "Beautiful China's Middle Ridge and Sustainable Development Goals" at the forum. "Should the 'Hu Huanyong Line' be broken? Can it be broken? How?" The Chinese senior asked three questions. He took the lead in organizing more than 40 experts and scholars in related fields, using space technology, supported by big data concepts and technologies, in the comprehensive On the basis of considering nature, economy, society, population and policy, after in-depth investigation and research, specific suggestions such as "inheriting the east and connecting the west, and mutually supporting the north and the south, and building a 'beautiful China's central ridge'" are put forward.

　　Guo Huadong pointed out that the two sides of the "Hu Huanyong Line" have beautiful scenery, rich products, colorful folk customs and splendid culture. In the future overall planning and design, the strategies of new urbanization, the revitalization of the Northeast, and the rise of the central region will be coordinated with the rural revitalization strategy, and the areas on both sides of the "Hu Huanyong Line" will be promoted to achieve a new common development of human-land coordination and balance.

　　He said that on the basis of two consultation reports submitted in 2016 and 2018 with a total of 8 recommendations, the research team will submit the third consultation report to the state in 2021, "Suggestions for Building a "Beautiful China Middle Ridge", which clearly states that "beautiful China's Middle Ridge Belt is strategically positioned as a high-quality comprehensive development belt, a new development space, a smart kinetic energy belt, and an important channel for China's domestic-international dual circulation. A comprehensive development zone for all aspects and the whole process of construction and social construction.

　　How to crack the "Hu Huanyong Line" by constructing the "Beautiful China Ridge Belt"?

Guo Huadong emphasized that the transition from the "Hu Huanyong Line" to the "Beautiful China Ridge Belt" is not only a simple transition from the "Division Line" to the "Contact Belt", but also a change in scientific cognition.

He said that the research team's "Suggestions for Building a "Beautiful China Middle Ridge" consulting report specifically put forward four suggestions:

　　One is to innovate the new model of western development by leaps and bounds and high-quality development as the starting point, tap new elements of western development, activate new kinetic energy for western development, and maintain a good environment for western development, including aiming at high-quality development goals and leaping into the ecological economic development model; Activate the advantages of resources and energy in the west to generate new development momentum; strengthen the targeted development of education in the west, and cultivate talents in the fourth industry; innovate and stabilize the talent environment, and make good use of talents without sticking to one pattern; maintain the comparative advantage of the northwest half of the wall and maintain a good environment in the west.

　　The second is to cultivate the "Beautiful China Middle Ridge Belt" as the country's regional strategy, and the whole society will jointly promote the development of the "Beautiful China Middle Ridge Belt".

Aiming at factors such as transportation, resources, ecology, policy, economy, tourism, and talents, comprehensive analysis and development of internal and external factors such as the advantages, disadvantages, opportunities, and threats of the overall development of the "Middle Ridge" are carried out.

　　The third is to build the "Beautiful China Middle Ridge Belt" into a hub of domestic and international circulation, a backbone belt for domestic circulation, and a promotion belt for international circulation, so as to build a new pattern of national regional development and land development.

The "Middle Ridge Belt" is located in the northeast-southwest connection hub. As the east-west linkage transmission belt, the new and old kinetic energy conversion belt and the dual-circulation hub, it can be built into an important starting area for the new economy of domestic demand and a promotion belt for external circulation.

At the same time, the "Middle Ridge Belt" has the ability to communicate the east and the west, undertake the geographical advantages of the north and the south, and carry major missions such as innovative development and healthy development.

　　The fourth is to build the "Beautiful China Middle Ridge Belt" into an ecological security barrier, an ecological security barrier for the east and the west, and a livable living belt.

It can be integrated with the national ecological screens on the east and west sides of the "middle ridge belt" to form a complete ecological security barrier.

　　At the 2nd "Beautiful China Middle Ridge Belt" Sustainable Development Forum, Academician Guo Huadong also presented the "HIST Sustainable Development Research Aihui Base" plaque to Aihui District, Heihe City, aiming to meet the United Nations Sustainable Development Agenda 2035 Sustainable development goals, docking with strategies such as "Beautiful China" and Northeast Revitalization, based on the social, economic, cultural, technological, ecological, tourism and other resources and endowment characteristics of Aihui District, aiming at regional sustainable development goals and approaches, under the guidance of HIST Carry out innovative research, application demonstration and development model promotion.
