摘　　要：近年来我国新一轮沿海区域发展战略不断上升为国家战略,海岸带环境系统压力趋大,以海岸带环境承载力评判断沿海地区发展的可持续性成为该地区首要关注的问题.本研究在分析海岸带环境承载力基本内涵和特征的基础上,将海岸带生态服务功能纳入指标体系,构建了由产业、人口、经济、岸线、滩涂、主要水污染物、典型生态敏感区等七大要素指标层组成的海岸带环境承载力评价指标体系,该指标层能较好地反映未来产业发展的增长变量和海岸带环境系统关键限制因素的定量或半定量关系.并提出指标量化方法和综合承载力定量评价方法,进而以北部湾经济区为实证,对未来规划情景的海岸带环境承载状况进行评价,为北部湾经济区重点产业发展战略的制定和实施提供科学的依据,对丰富和完善海岸带环境承载力评价的理论和实践具有较大的意义..Recently, several regional development strategies in China's coastal zones have become national. This will lead to huge pressures on the coastal environmental system. The assessment of Coastal Environmental Carrying Capacity(CECC) is one of the top concerned questions to determine the sustainable development of coastal areas.. Based on analysis of the concept and implication of CECC, the coastal ecosystem service was included in the CECC, which was represented as Sensibility of Vulnerable Ecosystem(SVE).The indicators of CECC were designed and structured, they consisted of indicators of sectors, population, economy, coastline, tidal mudflat, main water pollutants, and typical ecological sensitive zones. These indicators could reflect the relationship between the future economic growth and coastal environment quantitatively or quasi-quantitatively. The assessment method of CECC was also formed in this study. Then the Beibu Gulf Economic Zone(BGEZ) was used as a case study. The CECC assessement result could serve as a scientific reference for the local governments in the BGEZ. This study will enrich and improve the study of CECC in both theory and practice.
