摘　　要：海岛是海上陆地国土和人类开发海洋的远涉基地及前进支点。海岛大幅度地快速增长的开发活动与工程建设使脆弱的海岛生态环境正遭受到严重威胁。东山岛是福建第二大岛,近10年随着水产养殖与育苗、风电建设、环岛公路和房地产开发等海岛利用和开发强度的加大,海岛地质灾害及潜在风险陡增。基于现场调查和遥感影像解译,分析东山岛赋存的地质灾害类型及其分布,初步探究了主要地质灾害的诱因,为更有效地保护和可持续性开发东山岛,制定合理长效规划、防灾与减灾对策提供准确依据,并为福建及周边基岩岛的地质灾害调查与防治提供实测数据参考。Isand（s）（or islets）are sea land of one country and a base of utilizing and exploiting ocean of human be-ings,so they are becoming main carriers of promoting development of marine economic society and ecological envi-ronment.However,rapidly increasing development activities and engineering constructions on the island had made serious threats to the fragile ecological environment of theirs.The Dongshan Island is the second largest one in the Fujian Province.Before the 1990s,farming,fishing and aquaculture were the main ways of utilizing the island. With increasing economic activities such as aquaculture and breeding,wind power construction,island road and real estate development,geological disasters and potential risks to the island have been correspondingly increased.Based on interpretating remote sensing images and carrying out field investigations,this paper described the geological dis-aster types and its distribution in the island,and preliminarily discussed some causes leading to geological disasters, which are very helpful for more effectively protecting and sustainably developing the island.The results obtained in this study are the basis for designing future developing plans and generating strategies of disaster prevention and mitigation,and can be a reference for investigating and preventing geological disasters in rock island（s）in the Fu-jian Province and adjacent regions.
