摘要

众所周知,地面沉降是指地表逐渐降低或突然下沉,会对人类生活造成影响,对基础设施、公用设施线路和建筑物造成破坏,并改变地表排水系统和地下水状况。考虑到海平面上升、人口增长、海岸侵蚀加剧和极端事件的发生,以及洪水风险增加或淡水盐碱化(主要是在沿海城市),未来地面沉降的影响将更大。这项工作的主要目的是提供一个开源的、经过同行评审的综合数据库,确定 143 个沿海城市土地沉降的主要和次要原因。我们强调了在一些高风险城市仍不为人知的沉降潜在影响,以及不存在的缓解措施。该数据库还显示,缓解措施,特别是解决地下水开采引起的沉降问题的措施,在过去已被证明是成功的。拟议的数据库旨在增加研究人员、科学界、利益相关者和城市规划与发展决策者对沉降现象的了解,以及对全球土地沉降问题的认识。

Comprehensive database of land subsidence in 143 major coastal cities around the world: overview of issues, causes, and future challenges
Subsidence refers to the gradual lowering or sudden sinking of the ground surface and is known to impact human lives in terms of damages to the infrastructures, utility lines, and buildings as well as changes in the surficial drainage systems and groundwater conditions. The impacts of land subsidence will be greater in the future, considering the sea level rise, population growth, intensification of coastal erosion and extreme events, as well as increase in flood risk or freshwater salinization, mostly in coastal cities. The main aim of this work is to provide an open-source, peer-reviewed, and comprehensive database identifying the main and secondary causes of land subsidence in 143 coastal cities. We highlight the potential impacts of subsidence that are still unknown in some at-risk cities and non-existence of mitigation measures. The database additionally shows that mitigation measures, specifically those addressing subsidence due to groundwater extraction, have proven successful in the past. The proposed database aims to increase the knowledge on the subsidence phenomenon and also global awareness of land subsidence issues among researchers, the scientific community, stakeholders, and policymakers in terms of urban planning and development.

期刊介绍: Frontiers in Earth Science is an open-access journal that aims to bring together and publish on a single platform the best research dedicated to our planet. This platform hosts the rapidly growing and continuously expanding domains in Earth Science, involving the lithosphere (including the geosciences spectrum), the hydrosphere (including marine geosciences and hydrology, complementing the existing Frontiers journal on Marine Science) and the atmosphere (including meteorology and climatology). As such, Frontiers in Earth Science focuses on the countless processes operating within and among the major spheres constituting our planet. In turn, the understanding of these processes provides the theoretical background to better use the available resources and to face the major environmental challenges (including earthquakes, tsunamis, eruptions, floods, landslides, climate changes, extreme meteorological events): this is where interdependent processes meet, requiring a holistic view to better live on and with our planet. The journal welcomes outstanding contributions in any domain of Earth Science. The open-access model developed by Frontiers offers a fast, efficient, timely and dynamic alternative to traditional publication formats. The journal has 20 specialty sections at the first tier, each acting as an independent journal with a full editorial board. The traditional peer-review process is adapted to guarantee fairness and efficiency using a thorough paperless process, with real-time author-reviewer-editor interactions, collaborative reviewer mandates to maximize quality, and reviewer disclosure after article acceptance. While maintaining a rigorous peer-review, this system allows for a process whereby accepted articles are published online on average 90 days after submission. General Commentary articles as well as Book Reviews in Frontiers in Earth Science are only accepted upon invitation.
