摘　　要：依据大连市2005年遥感影像图,利用GIS技术,提取数据生成海洋岛土地利用专题图,以50m×50m为基本单位,制作格网作为辅助评价单元,通过网格化处理的生态风险指数及派生结果进行生态风险空间分布规律分析,并提出相关措施。结果表明:岭前村与西邦村生态风险威胁相对较大,并且,人类活动区及沿海产业集聚区生态安全现状也不容乐观。According to the remote sensing image of Dalian City in 2005,data were extracted and the thematic map of land use in Ocean island was generated by GIS technology.Creating the grid by 50m×50m as the auxiliary evaluation unit,then analyzing the spatial distribution of ecological risk through ecological risk index and the derived results produced by the grid with some relevant measures.The results showed that： the risk threat in Lingqian Village and Xibang Village is relatively large,besides,the ecological security state of the space where human activity and coastal industry gathered is also unoptimistic.
