Abstract

Introduction: Coastal areas are densely populated, economically developed, and form complex social-ecological systems. Any regional changes within these areas have profound consequences for their socio-economic development and ecological environments.Methods: Based on multi-source remote sensing image data, a detailed analysis of the coastline of the Ningbo-Taizhou-Wenzhou region (Yong-Tai-Wen region) from 1980 to 2020 was conducted, and the spatiotemporal changes of the coastline were analyzed. Regression analysis was employed to investigate the correlation between the coastline length and various factors, including the degree of industrialization, GDP, urban land, and arable land.Results and Discussion: The results show that: 1) From 1980 to 2020, the overall length of the coastline in the Yong-Tai-Wen region exhibited a decreasing trend, accompanied by a continual increase in the degree of artificial coastline. Consequently, the coastline became increasingly fragmented and tortuous. Notably, the intensity of coastline change fluctuated significantly, peaking in 2010. 2) At the regional scale, there is a strong negative correlation between the length of the coastline in the Yong-Tai-Wen region and GDP and land use, whereas the correlation with cultivated land area remains relatively low. Conversely, the proportion of human-made coastlines demonstrates a strong positive correlation with GDP and urban land use but a significant negative correlation with cultivated land area. 3) At the city scale, the length of the coastline in Ningbo shows a significant negative correlation with GDP while exhibiting a certain correlation with urban land use. Similarly, the coastline length in Taizhou also displays a strong negative association with both GDP and urban land use. In contrast, the correlation patterns observed in Wenzhou are opposite to those in Taizhou. Notably, the correlation between the length of the coastline and cultivated land area remains relatively weak across all three cities. Additionally, the proportion of artificial coastlines in Ningbo and Taizhou aligns with the overall trend in the Yong-Tai-Wen region. Specifically, the proportion of artificial coastlines in Wenzhou exhibits a positive correlation with GDP and urban land use and a negative correlation with cultivated land area.

区域经济发展对海岸线时空变化的影响：甬台温地区案例研究

导言：沿海地区人口稠密，经济发达，形成了复杂的社会生态系统。这些地区的任何区域变化都会对其社会经济发展和生态环境产生深远影响：方法：基于多源遥感影像数据，对宁波-台州-温州地区（甬台温地区）1980-2020 年的海岸线进行了详细分析，并对海岸线的时空变化进行了分析。采用回归分析法研究了海岸线长度与工业化程度、GDP、城市用地、耕地等多种因素的相关性：结果表明1）从 1980 年到 2020 年，甬台温地区海岸线总长度呈下降趋势，同时人工海岸线程度持续上升。因此，海岸线变得越来越破碎和曲折。值得注意的是，海岸线变化的强度波动很大，在 2010 年达到顶峰。2) 在区域尺度上，甬台温地区的海岸线长度与 GDP 和土地利用之间存在较强的负相关，而与耕地面积之间的相关性则相对较低。相反，人造海岸线的比例与 GDP 和城市土地利用呈很强的正相关，但与耕地面积呈显著的负相关。3) 在城市尺度上，宁波的海岸线长度与 GDP 呈显著负相关，而与城市土地利用呈一定的相关性。同样，台州的海岸线长度也与 GDP 和城市土地利用呈较强的负相关。相比之下，温州的相关模式与台州相反。值得注意的是，三个城市的海岸线长度与耕地面积之间的相关性仍然相对较弱。此外，宁波和台州的人工海岸线比例与甬台温地区的整体趋势一致。具体而言，温州的人工海岸线比例与 GDP 和城市用地呈正相关，与耕地面积呈负相关。

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.
