摘　　要：开展广东省滨海城市生态脆弱性评价研究,可以优化研究区域的生态环境措施,降低生态风险,进而促进沿海城市的可持续发展。因此量化评估城市生态脆弱性,掌握其生态脆弱性分布情况,是本研究的核心问题。研究选取广东省14个滨海城市,结合广东省风暴潮灾害情况,基于“生态敏感性-生态恢复力-生态压力(SRP)”模型构建评价体系,分析研究区域生态脆弱性状况、空间分布特征及其影响因素。结果表明:①广东省滨海城市生态脆弱性存在较大差异,生态脆弱指数相差0.369,深圳市生态脆弱性最大,阳江市生态脆弱性最小;②广东省滨海城市生态脆弱性空间分布呈中间高,两边低的空间分布特征;③各地区生态脆弱性的影响因素有所不同,这和各地区经济发展水平、开发建设程度、生态状况和受灾程度紧密相关,其致使各城市在敏感性、恢复力和压力表现不同。Carrying out the evaluation of ecological vulnerability of coastal cities in Guangdong Province can opti⁃mize the ecological environment measures in the study area,reduce ecological risks,and then promote the sustainable development of coastal cities.Therefore,quantitative assessment of urban ecological vulnerability and grasping the distribution of ecological vulnerability are the core issues of this study.The study selected 14 coastal cities in Guangdong Province,combined with the storm surge disaster situation in Guangdong Province,and constructed an evalua⁃tion system based on the"ecological sensitivity-ecological resilience-ecological pressure(SRP)"model to analyze the ecological vulnerability,spatial distribution characteristics and its influencing factors.The results show that:①There are large differences in the ecological vulnerability of coastal cities in Guangdong Province,with a difference of 0.369 in the ecological vulnerability index;Shenzhen has the largest ecological vulnerability,and Yangjiang has the smallest ecological vulnerability.②The spatial distribution of ecological vulnerability in coastal cities in Guangdong Province is high in the middle and low on both sides.③The influencing factors of ecological vulnerability in different regions are different,which are closely related to the level of economic development,development and construction,ecological status and disaster degree of each region,which results in different cities in sensitivity,resilience and pressure.
