摘要:
我国海岸带资源丰富,整治修复海岸带的生态和社会效果日益显现。本文基于石岛湾海岸带保护修复工程,对修复后的岸滩稳定性进行了评估。评估结果表明,石岛湾北流口段沙滩修复工程的NBSI的值为3.94,根据砂质海岸线的稳定性指数,该区域的岸滩稳定性等级极高,处于极稳定状态;桃园村段沙滩修复工程的NBSI的值为3.1,根据砂质海岸线的稳定性指数,该区域的岸滩稳定性等级较高,处于稳定状态。总体上来讲,石岛湾海岸带保护修复工程的岸滩稳定性等级较高,该工程的岸滩总体上处于稳定状态。China has abundant coastal resources, and the ecological and social effects of coastal remediation and restoration are increasingly evident. This article evaluates the stability of the restored beach based on the Shidao Bay coastal zone protection and restoration project. The evaluation results indicate that the NBSI value of the beach restoration project in the Beiliukou section of Shidao Bay is 3.94;according to the stability index of the sandy coastline, the stability level of the beach in this area is extremely high and in an extremely stable state;the NBSI value of the beach restoration project in Taoyuan section is 3.1, according to the stability index of the sandy coastline, the stability level of the beach in this area is relatively high and in a stable state. Overall, the stability level of the Shidao Bay coastal zone protection and restoration project is relatively high, and the beach of the project is generally in a stable state.
