沿海农用地、工业用地和城市用地的围垦在中国沿海地区广泛发生。近几十年来，中国所有沿海省市都经历了与经济快速增长和城市化导致的土地稀缺有关的严重沿海围垦。然而，直到最近许多发达国家开发出有利的方法将填海造地恢复为沿海湿地，沿海湿地和生态系统的价值才被很好地理解和认识。这项研究的总体目标是提供沿海围垦的详细时空分布；分析沿海经济、人口增长和城市化等驱动因素；了解驱动因素与土地围垦之间的关系。我们利用1985年至2010年的陆地卫星图像时间序列，每隔5年，结合遥感图像解译和空间分析，绘制了中国沿海地区的围垦现状和变化。陆地卫星图像的时间序列分析也被用来评估经济、人口和城市化驱动因素对海岸围垦的影响。分析结果表明，从1985年到2010年，沿海各省市共开垦滨海湿地754,697公顷，2005年后这一趋势急剧增加。高强度的沿海围垦主要是由经济的蓬勃发展推动的，特别是在2000年之后，与中国所在的沿海地区的城市化和工业发展相关；这与人均国内生产总值密切相关。沿海地区的持续大规模围垦，意味着中国面临着巨大的挑战，包括在未来变化的气候条件下，沿海植被湿地的巨大损失，对环境的负面影响，以及与沿海洪涝有关的潜在灾害风险。基于生态系统的长期海岸保护和管理对于支持中国未来可持续的海岸生态系统至关重要。
The reclamation of coastal land for agricultural, industrial, and urban land use—a common worldwide practice—has occurred extensively in the coastal region of China. In recent decades, all coastal provinces and metropolises in China have experienced severe coastal reclamation related to land scarcity caused by rapid economic growth and urbanization. However, the value of coastal wetlands and ecosystems has not been well understood and appreciated until recent development of advantageous methods of restoring reclaimed land to coastal wetlands in many developed countries. The overall objective of this study is to provide detailed spatial and temporal distributions of coastal reclamation; analyze drivers such as coastal economy, population growth, and urbanization; and understand the relationships among the drivers and land reclamation. We used long-term Landsat image time series from 1985 to 2010 in 5-year intervals, in combination with remotely sensed image interpretation and spatial analysis, to map the reclamation status and changes across the coastal region of China. The Landsat images time-series analysis was also conducted to evaluate the effects of the economy, population, and urbanization drivers on coastal reclamation. The analysis results indicated that 754,697 ha of coastal wetlands have been reclaimed across all coastal provinces and metropolises from 1985 to 2010, and the trend increased sharply after 2005. High-intensity coastal reclamation was mainly driven by the booming economy, especially after 2000, associated with urbanization and industrial development in China's coastal region; this was closely correlated with the gross domestic product (GDP) per capita. The continuous large-scale coastal reclamation of its coastal region now means China is facing a great challenge, including the enormous loss of vegetated coastal wetlands, negative environmental effects, and potential disaster risks related to coastal flooding under future change climate conditions. Long-term ecosystem-based coastal protection and management are critical to support sustainable coastal ecosystems in China in the future.
