摘　　要：随着沿海地区经济的快速发展,海岸带生态环境所面临的形势愈发严峻.为了掌握浙江省大陆岸线变迁特征及其驱动因素,实现海洋的可持续发展,选取其沿海27个区(县)为研究区,采用岸线变迁强度、人工化指数和开发利用强度等多种定量化分析手段研究其时空分布特征,并通过灰色关联度模型对浙江省大陆岸线演变的驱动因素进行了分析.结果表明:1)1995—2020年,浙江省的大陆岸线变迁强度逐渐加强,人工岸线逐渐增加,人工化指数由0.57增长到0.69,但增速逐渐趋于缓慢;2)研究区各时段的岸滩面积之和大于总时段的岸滩面积,说明浙江省大陆岸线在不断向海扩张的同时也发生了部分侵蚀;3)综合各项指标来看,1995—2020年,浙江省大陆岸线受人类干扰程度呈现先加剧后减缓的趋势;4)按选取的指标与岸线长度关联度平均值由大到小排序为年末人口总数、年平均温度、年降水量、渔业养殖面积、渔业生产总量、居民用地面积和GDP.With the rapid economic development of coastal areas,the situation of coastal ecological environment became more and more serious.In order to grasp the changing characteristics and driving factors of continental coastaline in Zhejiang Province,and achieve the sustainable development of the ocean,27 coastal districts and counties were selected as the study area,and their spatial-temporal distribution characteristics were studied by using a variety of quantitative analysis methods,such as the intensity of coastline change,artificial index and utilization,and the driving factors of continental coastline evolution in Zhejiang Province were analyzed by using the gray correlation model.The results showed that:1)From 1995 to 2020,the intensity of continental coastaline change in Zhejiang Province had gradually strengthened,and the artificial shoreline had gradually increased.The artificial index increased from 0.57 to 0.69,but the speed gradually tended to slow down;2)The sum of beach area in each period of the study area was larger than that in the total period,which indicated that the continental coastaline of Zhejiang Province had been partly eroded while expanding towards the sea;3)According to various indicators,from 1995 to 2020,the degree of human interference on the continental coastaline of Zhejiang Province showed a trend of first increasing and then decreasing;4)According to the average value of the correlation degree between the seven indicators and the length of the coastline,the total population at the end of the year,annual average temperature,annual precipitation,fishery breeding area,total fishery production,residential land area and GDP were sorted from large to small.
