Abstract:The Yellow River is the main birthplace of Chinese civilization and the mother river of the Chinese nation. On September 18, 2019, President Xi Jinping presided over a symposium on ecological protection and high-quality development of the Yellow River Basin in Zhengzhou and delivered an important speech, elaborating a major strategic deployment to strengthen ecological protection and promote high-quality development. The lower-reaches of the Yellow River Basin have sound conditions for agricultural development, but the high-quality agricultural development in the Yellow River Delta still faces many challenges. Chinese Academy of Sciences (CAS) has a soild scientific research foundation in the Yellow River Delta. It has proactively deployed scientific research bases and started numbers of scientific research projects which has achieved significant scientific research results. Based on long-term research, and around the strategic goals of ecological protection and high-quality development of the Yellow River Delta, a method for further transforming development thinking was put forward, through effective combination of ecological principles and high-tech, and adaptive development of saline-alkali land, efficient and refined development of saline-alkali land, and modern industrial development, to explore a new pattern of efficient, high-quality, and high-value development of saline-alkali land agriculture in the Yellow River Delta. By exploring new mechanisms for agricultural scientific and technological innovation, activating scientific and technological innovation capabilities and service capabilities, a batch of key technologies will be breakthrough for high-quality agricultural development in the Yellow River Delta, therefore proposing a "CAS's Solution" and establishing a "CAS's Model".
