   地球系统圈层内与圈层间复杂的物理、化学、生物和人为过程，使表层地球系统成为非线性和关联而复杂的动态系统，塑造了其结构与功能的演化，决定了圈层之间的物质和能量流动与反馈。全球变化和人为活动双重作用下，地球系统各圈层间及其内部的关键物质循环过程发生剧烈变化，深刻影响其生态服务功能，使社会-生态系统可持续性面临诸多挑战，需要多学科交叉合作和综合集成研究，明确地球系统多圈层、多界面、多尺度、多要素的复杂动力学过程，揭示地球系统各组成部分之间的相互作用和反馈机制，以科学应对全球变化，促进人与自然和谐共生。本专题将以地球圈层相互作用与全球变化为核心议题，重点探讨以下三个方向：

   专题 1.1地球圈层演变过程：主要聚焦构造、气候和人类活动作用下地球圈层结构和组成演化。
   专题 1.2 人类世水与生物地球化学循环：聚焦人类世全球变化的人类活动的驱动力特征、水与生物地球化学循环在地球系统各圈层演化中的作用及其变化规律。

   The complex physical, chemical, biological, and human-induced processes within and between the Earth's spheres make the surface Earth system a nonlinear in terms of function evolution, and the flow and feedback of matter and energy between subsystems. Under the dual impact of global change and human activities, the key material cycling processes between and within the Earth's spheres undergo drastic changes, profoundly affecting their ecological service functions and posing numerous challenges to the sustainability of social-ecological systems. A clear understanding of the surface Earth system thus requires interdisciplinary collaboration and integrated research methodology to delineate the system dynamics and processes, and to reveal the interactions and feedback mechanisms between the Earth system's components.

   Session 1.1 Evolution of Earth's Spheres:The evolution of the structure and composition of Earth's spheres under the influence of tectonic, climatic, and human activities.
   Session 1.2 Anthropocene Water and Biogeochemical Cycles:The driving characteristics of human activities in global changes during the Anthropocene, and the role and changing patterns of water and biogeochemical cycles in the evolution of various spheres of the Earth system.
   Session 1.3 Interactions Among Spheres and Their Environmental Effects:Complex dynamic interactions and feedback mechanisms among the lithosphere, soil, water, atmosphere, and biosphere at multiple temporal and spatial scales, and their constraints on the evolution of Earth system functions.

地球和人类进入了新的地质时代，即人类世，从此人类历史就是地球的历史。人类世是“人类活动作为主要的外部地质营力对地表形态、地球环境和生态系统产生巨大影响，地球系统演化改变了原有速率和方式，进入了受自然与人类共同影响的新地质历史阶段”。由于人类活动作为主导驱动力导致地球环境和社会系统加速变化，并改变了我们与环境和生物圈的关系。应对人类世的全球变化实现可持续发展，我们需要发展地球系统科学，研究认识人类世社会-自然系统动力学特征，尤其是系统适应性、脆弱性和可恢复性等有关的系统稳定性变化规律，以及人类福祉与自然环境之间的主要得失权衡等；我们需要构建地球系统科学多学科交叉综合研究范式，实现自然和人文社会科学领域的跨学科交叉融合研究。同时，我们也需要变革人类社会、人文和科学思维和创新现有科学和技术，认识和理解人类世的科学认知结构如何变化、科学如何服务社会、在人类世科学家的交流和参与实践及其形式如何变化。

利用系统科学理论和方法研究包括人类世以来人类系统作为不可分割的子系统构成的整体地球系统的变化，代表着地球系统科学发展的新跨越，是当今世界重要的最综合集成和学科交叉研究的新兴学科领域。当前人类社会尤其我国社会经济的可持续发展面临资源和能源消费量庞大、水土资源问题严峻、环境污染加剧、生态系统退化、极端气候事件和自然灾害频发等资源、生态、环境和气候等方面的诸多挑战。可持续发展问题在过程和结果上是错综复杂的、在尺度上是多层次的，并最终表现为系统性和全球性。因此，人类命运共同体、美丽中国的建设和人类社会可持续发展的实现需要亟待推动多学科交叉融合研究的地球系统科学的发展。

天津大学地球系统科学学院秉持将国际前沿地球系统科学及其相关学科研究与国家/地方需求相结合，致力于发展地球系统科学的理论和方法，进行多学科交叉和综合集成的系统科学研究，尤其是地球层圈相互作用与全球环境变化、社会-生态系统与可持续性科学方向的发展，为自然资源管理和灾害防治、区域发展和规划、科学研究和教学、经济和社会的可持续发展以及公共健康和安全服务。学院已获批全国首个地球系统科学博士/硕士学位点，基于此，在当前新形势下定于2023年8月6-9日在天津召开第四届表层地球系统科学国际学术会议，广邀国内外知名专家，围绕地球系统科学前沿方向，聚焦地球系统观测、全球变化以及可持续发展，共同探讨地球系统科学前沿问题和可持续发展领域重大关切，共享最新研究成果，以促进多学科交叉融合和地球系统科学学科发展。

Earth and humanity have entered a new geological epoch known as the Anthropocene, where human history becomes the history of the Earth. The Anthropocene represents a geological era characterized by significant influences of human activities as the primary external geological force, leading to immense impacts on landforms, global environments, and ecosystems. The evolution of the Earth system has been altered in terms of rates and processes, entering a new phase influenced jointly by nature and human activities. This transformative era has accelerated changes in the Earth's environment and societal systems, fundamentally altering our relationship with the environment and the biosphere. To address the global changes of the Anthropocene and achieve sustainable development, it is crucial to advance the field of Earth system science. This entails studying and understanding the dynamics of the socio-natural systems within the Anthropocene, particularly focusing on aspects such as system adaptability, vulnerability, resilience, and the changing patterns of system stability. Additionally, it involves examining the trade-offs between human well-being and the natural environment. Furthermore, the development of a comprehensive interdisciplinary research framework in Earth system science is essential. This framework should facilitate the integration of natural and social sciences, enabling cross-disciplinary collaboration to explore the complex interactions within the Anthropocene. Simultaneously, it is necessary to transform human societies, humanities, and scientific thinking, as well as innovate existing scientific approaches and technologies. This transformation should encompass an understanding of how the scientific cognitive structure within the Anthropocene evolves, how science can better serve society, and how the forms and practices of communication and participation among scientists change in the Anthropocene era.

The utilization of systems science theories and methodologies to study the changes in the Earth system, which includes the inseparable subsystem of human systems since the inception of the Anthropocene, represents a new leap in the advancement of Earth system science. It stands as an emerging discipline that is highly integrative and cross-disciplinary, holding significant importance in today's world. At present, the sustainable development of human society, especially China's economy and society, is facing many challenges in resources, ecological environment and climate, such as huge resource and energy consumptions, severe problems of water and soil resources, intensification of environmental pollution, ecosystem degradation, extreme weather events and frequent natural disasters. Sustainable development issues are complex in their processes and outcomes, occurring at multiple hierarchical scales, and ultimately manifesting as systemic and global challenges. Therefore, the realization of a shared human destiny, the construction of a beautiful China, and the achievement of sustainable development for human society necessitate the urgent promotion of interdisciplinary research within the field of Earth system science.

在自然过程和人类活动共同作用下，地球表层系统复杂多变。如何协调人与环境的矛盾、保持可持续发展是我们社会极其关切的问题。近几十年来，气候变化明显，人类活动持续增加，深刻改变着地表过程，并对人类赖以生存的生态系统产生威胁。未来，随着人口及能源消耗的增加，人类活动对环境的影响将会变得更加显著。由于地表系统驱动着圈层间物质和能量的交换，因而我们需要更加深入的了解自然和人类活动双层压力下地表系统的功能演变。本次表层地球系统科学会议将聚焦气候和环境变化及其对人类-环境系统的影响，讨论人类活动需要做出什么改变和修正以应对当前的挑战，探索如何合理利用自然资源以维持人类社会可持续发展。

The surface-earth system is constantly changing under the influence of natural and anthropogenic forces. How to maintain a sustainable development is a long-standing concern with the changing spatial compartment and material character of the Earth surface and with the reciprocal relationship between human beings and the environment, and is becoming increasingly central to both natural science and society. In recent years, dramatic climate change and increased human activities have profoundly altered the Earth surface processes and are posing ecological challenges. Moreover, the environmental impacts of anthropogenic activity are expected to increase as the world becomes more populated and energy-consuming. As the surface-earth system directly drives material and energy exchanges within/between the different surface compartments and human beings, more efforts must be made to better understand the function of the surface-earth system under such natural and human pressures. This SESS conference will focus on the recent research achievements on how climate and other environmental changes are affecting the vulnerabilities of coupled human–environment systems, how changes and modifications should be made for human activities, and how natural resources should be used in order to maintain a sustainable development.
