摘　　要：根据2005年厦门海洋工程勘察设计院对青兰山—福建炼油厂海底管线和污水排海管线海上路由调查资料,对30个样品9个环境因子数据的综合分析和数理统计,论述了环境因子的存在特征,揭示了某些因子之间的相关关系和共生组合.对样品进行Q型因子分析,显示出30个样品按腐蚀性大小,分为3个点群.通过评价指标得分得出:就本研究区而言,东部区域腐蚀性较强.通过比对分析发现:本海区底质环境优于台湾海峡西部其他海域,较适合海底工程建设.该研究结果对海底工程建设具有指标意义.According to the investigation data on the pipeline and sewerage pipeline by Ocean Engineering routing survey of Qinglan hill-Fulian sea bottom Reconnaissance and Design Academe in Xiamen in 2005, this paper presents an integral analysis and mathematical statistic at 30 stations and 9 environmental factors, describes the existing characteristics of the environmental factors, and reveals correlation as well as symbiotic relations among certain factors. By the Q-factor analysis, samples at 30 stations are separated into three groups according to their difference in erosiveness. From the evaluation index results, it is concluded that the erosiveness in the eastern is higher than in other parts for current investigation region. Further comparison shows that the benthonic environment in the current investigation region is better than other zones located in the western part of the Taiwan straits, which means that the current region is more suitable for benthonic construction. The present study is dedicated to provide a guideline for benthonic construction in the area.
