珊瑚礁海岸侵蚀的影响因素与响应特征分析

Analysis of Influencing Factors and Response Characteristics of Coral Reef Coastal Erosion

珊瑚礁海岸作为常见的生物海岸类型,在我国南海区域普遍发育。全球气候变化和海岸带人类开发活动的影响导致珊瑚礁海岸的侵蚀现象普遍发生。本文以我国珊瑚礁海岸为研究对象,结合前人研究资料,探讨分析珊瑚礁海岸侵蚀的特征、复杂性和不确定性,尝试分析珊瑚礁海岸侵蚀的影响因素。研究得出珊瑚礁海岸侵蚀原因包括珊瑚礁生态因素和海岸因素。海岸侵蚀原因要素在珊瑚礁海岸表现形式上不同,其时空尺度响应有所差异,主要表现为对海平面上升、风暴和大浪潮因素带来的负面影响的减缓和降低;对导致发育环境恶化的气候变化因素的敏感反应,响应则更为快速和明显。

Coral reef coast, as a common type ofbiological coast, is widely developed in the South China Sea. The impacts ofglobal climate change and human development activities in coastal zones haveled to widespread erosion of coral reef coasts. In this paper, thecharacteristics, complexity and uncertainty of coral reef coastal erosion arediscussed and analyzed based on the understanding of the previous research data,and the influencing factors of coral reef coastal erosion are analyzed. It isconcluded that the causes of coral reef coastal erosion include coral reefecological factors and coastal factors. Coastal erosion causes have differentmanifestations in coral reef coasts, and their spatial and temporal scalesrespond differently. The main manifestations are the slowdown and reduction ofnegative impacts caused by sea level rise, storm and big wave factors, and themore rapid and obvious response to climate change factors that lead todeterioration of development environment.
