摘要:
基于福建省泉州湾过去 40 多年（1973—2016）的卫星遥感影像数据 , 通过海岸线提取的方法 , 对比 分析不同时间段泉州湾岸线长度、面积、结构和分形维数变化情况 , 获得该研究区1973—2016 年海岸线时 空变迁的特征。泉州湾海岸线长度总体呈增长趋势 , 研究期内总长度增加 9940 m, 其中 1973—1990 年岸线 总长度略有缩减 , 而 1990 年之后呈增长趋势。海岸线持续向海扩进 , 由此增加海岸总面积约 26 km2。具体 而言,1973—1990年、1990—2000年和2000—2016年分别增加了10.34 km2、3.98km2 和12.61 km2。区内基岩、 砂质、泥质海岸的岸线长度呈下降趋势 , 人工岸线长度大幅度增加 , 基岩、砂质以及泥质海岸的岸线向人工 岸线转变趋势明显 , 类间连线效应持续增强。研究区岸线分形维数变化趋势和岸线长度变化趋势一致 , 成正 相关关系。围垦养殖、港口扩建和城市建设等人类活动造成陆地向海洋延伸 , 是造成研究区岸线变迁的主要 原因。
Abstract:
Based the satellite remote sensing image data of the Quanzhou Bay in Fujian province over the past 40 years (from 1973 to 2016),spatial and temporal change characteristics of coastline in this area were analyzed by coastline extraction method,including comparative analysis of the changes in the coastline length,bay area,structure and fractal dimension in different periods. In generally,the coastline length of the Quanzhou Bay shows a increase trend, and the total length increased by 9 940 meters during the study period. The total length of coastline has decreased slightly from 1973 to 1990,whereas,it has shown an increasing trend since 1990. The coastline migrated seaward successively,leading to an increase in the coastal zone of 26 km2. During 19731990,1990-2000 and 2000-2016,the coastal zone increased by 10.34 km2,3.98 km2 and 12.61 km2,respectively. The length of bedrock,sandy and muddy coastline in the Quanzhou Bay was declining,and the length of artificial shorelines has increased significantly. The trend of coastline shift from bedrock, sandy and muddy coast to artificial coast was obvious and its inter-category connection became stronger. The change trend of coastline fractal dimension is consistent with its length changing trend with a positively correlation. Human activities such as reclamation and breeding,port expansion and urban construction have caused the extension of the bay area,which are the main reasons for coastline changes of the study area.
