| 摘 要： | 采用能值分析的方法对青岛市大岛这一无居民海岛的承载力进行了研究。在大岛生态系统外边界界定为由其海岸线向海一侧扩展1 km范围的情况下,得出以下结论:大岛生态系统每年能值使用量为8.43E+18sej,其中潮汐能提供了绝大部分的能值;大岛生态系统的经济价值为1.16E+07元/a;在维持大岛生态系统可持续发展的情况下,其承载力为1 130人,但是其能值贡献主要来自于大岛周边海域生态系统。

| Abstract: | An energy evaluation was carried out to assess the carrying capacity of an uninhabited island in Qingdao.The sea area within 1 km of shoreline in the island was included in the evaluation,conclusions as follow.The total energy input to Da Island is 8.43E+18sej,with the most energy from tidal energy.The economic value of Da Island is 1.16E+07元/a.The carrying capacity of Da Island is 1130 people for a suitable development,and most of contributions come from the marine ecosystem around Da Island. |
