The Xi Bailian Island in Zhoushan city is chosen as the case study area to establish a quantitative evaluation model for the ecological stress of the island by analyzing the characteristics of the island ecosystem and the driving factors of the ecological stress. The calculation result shows that the ecological stress value of the Xi Bailian Island from 2008 to 2012 are 0.2345, 0.3016, 0.3797, 0.3604 and 0.3503. With reference to the offshore environmental functional zoning of Zhoushan city, Xi Bailian Island is located in the level 4 sea water quality area, of which the calculation result of standard value is 0.5490. The analysis results show that the ecological stress value of the island doesn’ t exceed that required by the relevant national planning, while the main driving factors are land reclamation. The analysis results can provide references and decision basis for the ecological protection of island and rational utilization of resources.%舟山市西白莲岛屿为例，通过分析其生态系统特征和生态压力驱动因子，构建海岛生态压力定量评估模型，计算结果显示西白莲岛从2008年到2012年的生态压力值分别为0.2345、0.3016、0.3797、0.3604、0.3503，参照舟山市近岸海域环境功能区划，西白莲岛地理位置处于四类海水水质环境，四类海域标准值计算结果为0.5490。与四类水质比较结果显示该岛屿生态压力值均未超出岛屿承载能力，主要的压力驱动因子为填海造地，分析结果为海岛生态保护与资源合理利用提供参考和决策依据。
