Abstract

Coastline is the connection line between the land and the sea, and its extraction and analysis are of great significance to the coastal zone resources and environmental protection. Using remote sensing and Geographic Information Sysytem (GIS), coastline change from 1995 to 2015 in the Fujian Province, China, was extracted. The temporal and spatial evolution characteristics of coastline length, type and spatial location in the Fujian Province, China were analyzed. The coastline length continued to increase from 1995.29 km to 3555.036 km. The overall change intensity in 2010-2015 was the highest, reaching 0.87%, followed by 1995-2000. The smallest change occurred in 2005-2010. Based on the intensity changes in the six coastal cities of Fujian Province, Zhangzhou City showed the strongest coastline change. Except for the stability in 2000-2005, the changes that occurred during other years were larger. Fuzhou is the city with the smallest coastline changes, which have remained balanced for 25 years. Overall, the length of the rocky coastline and the sandy coastline generally show a downward trend, while the artificial coastline and the muddy coastline generally show an upward trend.

1995 - 2015年福建省海岸线变化的时空分析

海岸线是陆地和海洋的连接线，海岸线的提取和分析对海岸带资源和环境保护具有重要意义。利用遥感和地理信息系统（GIS），提取了福建省1995年至2015年的海岸线变化。分析了福建省海岸线长度、类型和空间位置的时空演变特征。海岸线长度继续增加，从1995.29公里增加到3555.036公里。2010-2015年的总体变化强度最高，达到0.87%，其次是1995-2000年。变化最小的发生在2005-2010年。从福建省沿海六市的强度变化来看，漳州市海岸线变化最为强烈。除了2000-2005年的稳定外，其他年份发生的变化更大。福州是海岸线变化最小的城市，25年来一直保持平衡。总体而言，岩石海岸线和沙质海岸线的长度总体呈下降趋势，而人工海岸线和泥质海岸线总体呈上升趋势。

期刊介绍： The Journal of Environmental Science and Management (JESAM) is an international scientific journal produced semi-annually by the University of the Philippines Los Baños (UPLB). JESAM gives particular premium to manuscript submissions that employ integrated methods resulting to analyses that provide new insights in environmental science, particularly in the areas of: environmental planning and management; protected areas development, planning, and management; community-based resources management; environmental chemistry and toxicology; environmental restoration; social theory and environment; and environmental security and management.
