无居民海岛生态环境特殊且具有其重要价值和地位,对无居民生态岛建设评价的研究,有助于更好地实现中国海岛的生态保护和有序开发。本文以PSR模型为指标框架,参考国内外各类生态评价指标,采用文献分析法、德尔菲法、模糊评价法等方法逐步筛选适合指标,初步建立包括生态风险、生态现状、生态保障为主系统层的包含9个评价指标的无居民生态岛建设评价指标体系,并将大洲岛作为典型案例进行示范评价。结果表明：该指标体系的评价结果能够较好的反映大洲岛的生态建设状况,具有较强的实际意义与较好的实践应用价值。

英文摘要：

Ecological environment of uninhabited island is unique and possesses important value and status.Study of construction assessment about uninhabited island will help ecological protection and orderly development of islands in our country.Choosing PSR model as a frame,referring to ecology evaluation systems home and abroad,screening indexes gradually（by using literature analysis,Delphi method,fuzzy assessment,etc）to built an indicator system about eco-island construction for uninhabited islands preliminarily.The system includes 9indexes of which main system layer has ecological risk,current situation and protection.And Dazhou island is used as a typical case to demonstrate the assessment.The result shows that the assessment of this indicator system is able to reflect the ecological construction situation of Dazhou island well,which means it has good practical significance and application value.
