Abstract: The withdrawal and rejoin of the United States from the Paris Agreement shows that Irrational social factors are hindering the self-discipline development of Earth Science. The Earth Science field centered by scientists can effectively resolve the external interference. In the process of Earth Science development, more and more scientific factors are involved, the field structure is gradually expanded, and the force relationship is becoming more complex, which enlarges the heteronomy influence of social factors. Liu Dongsheng's scientific practice indicate that Scientific spirit, scientific habits, scientific capital and social production, national system, internationalization process can form a positive operation mechanism of Earth Science field, The connotation and social function of Earth Science are increasing, maintaining its self-discipline can help us to accurately understand the evolution law of the earth system, promoting new cognition of human-land coupling relationship, and provide scientific basis for the realization of the national strategy of carbon neutrality and the construction of ecological civilization.

摘要： 美国政府退出和重新加入《巴黎协定》表明，非理性社会因素一定程度上阻碍地球科学自律性发展，以地学家为中心的地球科学场域能够有效化解外部干扰。地球科学发展过程中涉及的科学因子不断增多、场域结构逐步扩大，作用力关系日益复杂，放大了社会因子的他律性影响。杰出地学家刘东生的科学实践表明，科学精神、科学习性、科学资本和社会生产、国家体制、国际化进程等内外因素能够形成地球科学场域的良性运作机制。地球科学的自身内涵和社会功能日益丰富，维护它的自律性发展有助于准确认识地球系统演化机制，深化人地耦合关系新认知，为实现“碳中和”国家战略和生态文明建设提供科学基础。
