Strategic Study of CAE doi: 10.15302/J-SSCAE-2024.06.030
The resource recycling of organic solid wastes in urban and rural areas is crucial for the development of waste-free cities
and a circular economy. The carbon peaking and carbon neutralization goals proposed by China also impose new and higher requirements for the resource recycling of these multi-source organic solid wastes in urban and rural areas. This study summarizes the basic progress of the resource recycling of multi-source organic solid wastes in urban and rural areas in China from the perspectives of household wastes, sewage sludge, and agricultural wastes, and identifies the prominent problems in overall planning and top-level design, collaborative management and cost mechanism, as well as technological innovation and transformation. Moreover, it proposes three key technical paths for the resource recycling, including multi-source collaborative recycling centered on biological treatment,multi-source collaborative safe disposal centered on thermochemical treatment, and intensive/park-based collaborative disposal of multi-source organic wastes. Furthermore, the following suggestions are proposed: forming the medium- and long-term overall planning and top-level design for pollution and carbon reduction, improving the institutional system by establishing a cross-departmental collaborative management system and a market-based pricing mechanism, and strengthening interdisciplinary integration and industryuniversity-research-application collaboration to promote the innovative application of key core technologies and industrial upgrading.

Aeronautical engineering science and technologies involve multiple disciplines, high technical risks, large capital investment, and long development cycles; therefore, a long-term, stable development strategy is needed to achieve breakthroughs regarding the key core technologies of aeronautical engineering science and technologies and to realize the sustainable development of the aeronautical industry. This study summarizes the global development trend and China’s development status of aeronautical engineering science and technologies from four aspects: civil aircraft, aero engine, airborne system, and air traffic control system. It also identifies the development deficiencies in terms of basic research and technical reserves; system integration and product system research; aero engine technology; airborne system research, development, and testing; aeronautical maintenance capabilities; and industrial software and basic components. On this basis, a 20-year development vision for aeronautical engineering science and technologies in China is proposed, as well as key directions for future project deployment: supersonic passenger aircraft, high-speed rotorcraft, new energy aircraft, hybrid electric propulsion systems, next-generation air traffic control technologies, intelligent passenger aircraft, all-composite aero engines, and intelligent repair technologies for composite materials. Furthermore, the study suggests incorporating aeronautical power construction into national medium- and long-term strategic planning, strengthening the construction of a scientific and technological innovation system, enhancing interdisciplinary cooperation, and emphasizing international collaboration, thereby precisely supporting the development of aeronautical engineering science and echnologies in the next 20 years.

Airborne geophysical exploration is an important and rapid method for mineral prospecting. China’s airborne geophysical exploration technology has made great progress in the 21st century. However, existing technologies and equipment can hardly satisfy the new demand for key prospecting technologies and equipment for deep-Earth and deep-sea exploration in the new round of mineral prospecting breakthroughs in China. Focusing on the high-quality development of airborne geophysical exploration technologies in China, this study summarizes the development status of these technologies in China and abroad, evaluates the technological competition and development trends, and analyzes the major challenges faced by China in this field. Considering the new changes, characteristics, and trends of scientific and technological development, this study proposes a development roadmap of China’s airborne geophysics exploration technologies, aiming at frontier technologies, such as superconducting sensors, full-tensor airbornegravity gradient, full-tensor aeromagnetic gradient, multi-field-source full-depth airborne electromagnetism, and airborne seismic survey, as well as practical technologies urgently needed for the new round of mineral prospecting breakthroughs. Given the weaknesses in frontier research capability, technical adaptability, and innovation foundation, it is proposed to establish a national innovation center for airborne geophysical technologies, conduct the research and development of the fourth-generation airborne geophysical exploration technology, and build an integrated development system for airborne geophysical technical equipment.

The medical foundation model performs efficient processing and pattern recognition of complex medical data based on a deep neural network architecture, providing a new type of decision support for intelligent medical care. It is necessary to systematically analyze the technologies and application of the medical foundation model, thus to identify the development directions and challenges and improve the capabilities of the medical care sector in medical text writing, medical image recognition, medical equipment research and development, and medical education using the medical foundation model. This study sorts out the technology paradigm and application scenarios of the medical foundation model and proposes a technology system and an evaluation system for the model. The technology system is composed of a base layer, a model layer, an application layer, and a common module. The evaluation system involves the establishment of an evaluation index system, dataset range and question types, model alignment methods, and model evaluation platforms. Moreover, application challenges of the medical foundation model are identified in terms of data security, technical risks, implementing challenges, and ethics. Furthermore, the following countermeasures are suggested: (1) ensuring data security through government guidance, (2) accelerating basic theoretical research to address technic risks, (3) focusing on application scenarios to cope with implementing challenges, (4) improving the ethics regulating mechanism, and (5) perfecting the public service system to create an innovation ecosystem, thereby accelerating the innovative development of the medical foundation model and promoting the high-end, intelligent, and green development of intelligent medical care in China.

Agriculture is the foundation of a nation for achieving high-quality development and ensuring national security. This study establishes an index system for evaluating the construction of a strong agricultural country with Chinese characteristics, clarifies the problems and challenges faced by China, and proposes relevant countermeasures. Research indicates that China has a good foundation in ensuring the supply of agricultural products and enhancing the resilience of the agricultural industry. However, there remain major problems to be addressed regarding the supply of food and important agricultural products, agricultural technologies and equipment, agricultural management systems, resilience of the agricultural industry and supply chains, market competitiveness of agricultural products, and farmer income and rural development. To promote the high-quality development of agriculture in China, this study proposes the following countermeasures: (1) enhancing the supply capacity of China in terms of grain and important agricultural products, (2) improving the level of agricultural technologies and equipment, (3) strengthening the agricultural management system, (4) enhancing the resilience of the agricultural industry, (5) boosting agricultural competitiveness, and (6) promoting the common prosperity of farmers and rural areas.
