海岸带生态系统具有重要的防灾减灾、景观人文、社会及经济价值。但是海岸带系统也及其脆弱和敏感,容易受到人类活动和自然环境的影响。对受损的海岸带进行保护和修复是近年来国内外关注的重点。根据中央财经委第三次会议精神,威海市开展了海岸带保护修复项目。本文基于威海市石岛湾海岸带保护修复工程,对该工程对当地经济和社会效益的作用进行了调查和分析。调查结果表明石岛湾海岸带保护修复工程对当地经济实现产业升级和结构优化具有促进作用,同时对当地的旅游业也有极大地推动作用。Coastal ecosystems have important values in disaster prevention and reduction, landscape culture, society, and economy. However, coastal systems are also extremely fragile and sensitive, easily influenced by human activities and the natural environment. Protecting and repairing damaged coastal zones has been a focus of attention both domestically and internationally in recent years. According to the spirit of the third meeting of the Central Committee of Finance and Economics, Weihai has launched the coastal zone protection and restoration project. This article is based on the protection and restoration project of the Shidao Bay Coastal Zone, investigates and analyzes the impact of the project on the local economy and social benefits.
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.
