| 摘要: |
| 海岛是我国社会经济发展的重要战略空间，也是生态安全的重要屏障，评价海岛的生态状况是海岛合理利用和保护管理的基础。文章选取77个海岛为研究对象，根据海岛生态指数评价方法，对2019年各海岛生态状况进行评价。结果表明：评价海岛以生态状况优良海岛为主，乡镇级有居民海岛和无居民海岛生态状况显著好于村级有居民海岛，渤黄海区和东海区海岛生态指数分布相似，优良海岛比例高于南海区海岛。植被覆盖率、自然岸线保有率和污水处理率是影响海岛2019年生态状况的主要因素。重视和加强村级有居民海岛的生态保护与建设投入力度，合理利用海岛资源，优化保护与开发空间布局，尽可能地保留自然岸线，提高海岛污水处理能力，将有助于改善海岛生态状况，推动实现海岛的可持续发展。 |

| Abstract: |
| Islands are not only important strategic space for China’s social and economic development, but also important barrier for ecological security. Evaluating the ecological status of islands is the basis for rational utilization, protection and management. In this paper, 77 islands were selected and the ecological status of each island in 2019 was evaluated according to the evaluation method of Island Ecological Index. The results showed that the majority of evaluated islands were of good ecological status, the ecological status of township-level islands with residents and non-resident islands was significantly better than that of village-level islands with residents, the distribution of Island Ecological Index in the Bohai Sea, the Yellow Sea and the East China Sea was similar, and the proportion of islands of good ecological status was higher than that of islands in the South China Sea. Vegetation coverage, natural shoreline retention rate and sewage treatment rate were the main factors affecting the ecological status of islands in 2019. Effective measures should be taken to help improve the ecological status of islands and promote the realization of sustainable development of islands, such as strengthening the investment in ecological protection and construction of village-level islands with residents, rationalizing the use of island resources, optimizing the pattern of protection and development, retaining natural shorelines, improving the sewage treatment capacity and so on. |
