| 摘要: |
| 收集1949~2010年发生在广西沿海地区的主要海洋灾害情况,并对其进行风险影响分析。在影响广西沿海地区的主要海洋灾害中,风暴潮灾害最严重,造成的损失最大,直接危及到国家财产、沿海人民生命生活安全以及社会经济的可持续发展;其次是赤潮灾害和海水入侵灾害。气候变化与人类活动是引发这些灾害的主要影响因素。气候变化影响下的海平面上升使风暴潮的致灾程度加剧,海岸侵蚀、岸线变迁、海水入侵和土地盐渍化加重;人类大规模的围填海活动使潮滩湿地消失、生物多样性减少、赤潮危害加重、生态环境资源遭到破坏,加重灾害的危害程度。应采取工程与生态相结合的立体防护体系,提高海岸自然抗灾能力,将灾害损失及风险降至最低。 |

| Abstract: |
| The marine disasters occurred in Guangxi coastal areas between 1949 to 2010 were summarized and their risks were analyzed.The results show that the storm surge is the most serious marine disaster in affecting the Guangxi coastal areas, and its loss is also the largest, which directly endangers the national property, coastal people's life safety, and sustainable development of society and economy.The second serious marine disaster includes red tide and seawater intrusion.Two main influence factors that produced these disasters are climate change and disturbance of human activity.Sea level rise under the impact of climate change intensifies storm surge disaster, coastal erosion, seawater intrusion, shoreline change and land salinization.Human large scale reclamation activity causes tidal flat and wetland disappearing, biodiversity decreasing, red tide aggravating and ecological environment resources being destructed, and aggravates the disaster damage level.We should take dimensional protection system combined engineering and ecology to improve the ability of coast to resist natural disasters, in order to minimize the disaster losses and risk. |
