| 摘 要： | 基于历史图件对比方法和Bruun法则对广西北海银滩岸线的侵蚀进行评估和预测.结果表明银滩在近30a内海岸侵蚀达10.40 m/a,其中人类活动作用是造成海岸侵蚀的主要因素,人类活动对岸线位置蚀退的影响贡献为98%;海平面上升导致岸线蚀退的贡献仅为2%.然而,在未来100 a内,基于历史图件对比分析估算的银滩侵蚀宽度可能超过1 000 m,银滩环境将会发生退化.因海平面上升而对岸线蚀退的贡献权重增加为9%.由于人类活动导致的银滩退化可以进行控制和预防,故对未来海平面上升引发的银滩环境退化应该予以重点关注.

| Abstract: | Coastal erosion is an extremely complex natural phenomenon.Because of abnormalities of water and sediment passing from a river basin into the sea,expansion of social economic activities,and urbanization of shore region,coastal erosion has worsened in recent decades under the conditions of global warming and sea-level rise around the world.This poses a serious challenge to ecology and the environment in coastal regions.Although exploitation of the coast in Guangxi province has lagged that in other regions,th... |
