The Yellow River Basin stands as China's earliest geographical unit of human activity and remains the most vital economic zone and ecological barrier today. Its ecological conservation and high-quality development constitute a millennium-long strategy crucial to the rejuvenation of the Chinese nation. To scientifically understand the relationship between regional development and ecological protection in the basin and promote sustainable growth, the study analyzes geography-based issues through the fundamental concepts including river basins, economic belts, and metropolitan areas. First,defining the basin's scope requires precise balancing—neither overextending nor underestimating its boundaries. Development policies should align with actual needs, grounded in the region's geographical conditions, resource availability, and socio-economic foundations. Second, the “Yellow River Economic Belt” does not exist as a single entity at the national level. Third, high-quality development in the basin demands comprehensive coordination across economic, social, demographic, resource, environmental, and cultural dimensions. Ecological protection must serve as the foundation while economic growth forms the cornerstone, with each region pursuing differentiated development goals and tailored strategies.Moreover, the “Ji” character-shaped Yellow River metropolitan area should not be narrowly interpreted as a single urban cluster, as its spatial scope encompasses multiple metropolitan regions.
