中文摘要：利用聚类分析和模糊综合评价法对雷州半岛夏季近海海域57个监测站位的海水环境状况进行分析和研究,并提出相关的水质保证建议。结果表明:通过R型聚类方法可将17个监测指标缩减为6个主要成分指标,利用Q型聚类分析将雷州半岛57个监测站位大致划分为3类。模糊综合评价法同样将雷州半岛监测站位划分为3类。分别为一类海水,二类海水和四类海水。聚类分析和模糊综合评价具有一定相似性又有一定的互补性,更能科学、客观地反映环境的实际状况,对海域的规划和科学管理具有一定的指导意义。

外文摘要：The seawater quality was analyzed at 57 monitoring stations in the coastal area along the Leizhou Peninsula in summer based on the methods of cluster analysis and fuzzy comprehensive evaluation, and the proposals for pollu tion control was put forward. In the present study, the 17 monitoring indicators were reduced into the 6 principal com ponents by the R cluster method. The 57 monitoring stations were divided into 3 groups using the Q cluster method. The monitoring stations in Leizhou Peninsula coastal were divided into 3 sorts by the fuzzy comprehensive evaluation method, the firstclassed seawater, the secondclassed seawater and the fourthclassed seawater respectively. The sea water quality was better in surface seawater than in bottom seawater. The cluster analysis and fuzzy comprehensive e valuation revealed some similarities and complementarities. They reflected more scientifically and objectively the actu al environmental conditions, which was beneficial to guided the marine planning and management.
