| 摘 要： | 对海岸线变化和脆弱性的了解对地方政府部门非常重要，拥有这方面的知识将有助于进行沿海地区的管理和开发。为了研究海南岛的海岸变化特征及其脆弱性，近年来我们采集了大的沉积物样品，并结合海图和遥感卫片分析海岸线变化特征。海南四大城市（海口，文昌，三亚和长江）虽然没有显著的侵蚀特征（海岸线处于相对稳定状态），通过脆弱性评价发现其均为中等脆弱性，主要是由于大量人口对海岸造成的压力所致。因此，本文提出的基于包括人为-自然因素的海岸脆弱性评价方法，具有制定海岸带管理和适应性策略的运用潜力。

| Abstract: | Knowledge of coastline changes and vulnerability is of great importance to local government departments that are responsible for the management and development of coastal zones. To study the nature of change and vulnerability along the coasts of the Hainan Island, we collected a large number of sediment samples through the last few years, and reconstructed the changes of the coastline by combining the data of sediment grain-size analysis and the nautical charts/TM RS imaginary. Contrary to being almost free from erosion (as expected from the findings that the coastlines are in a relatively stable state), four major cities in Hainan (i.e., Haikou, Wenchang, Sanya and Changjiang) turned out to be suffered from a moderate coastal vulnerability primarily because of the large populations that impose considerable pressure on the coastlines. Thus, the assessment methodology utilized in this study, including both anthropogenic and natural factors, serves as a useful tool to obtain a comprehensive understanding of coastline vulnerability for local government, in terms of coastal management and adaptation. |
