摘　　要：在收集南海以及台湾周边海域1900—2004年共105年的海洋调查资料,按0.5°×0.5°网格进行计算统计分析密度跃层的基础上,参考总参气象水文中心和国家海洋信息中心研制开发的中国海海洋水文分析应用系统,以及相关海洋水文图集,阐明了整个中国海密度跃层的海区和季节特点及其变化规律。中国海地理、气象和水文条件具有明显的多样性,致使密度跃层类型多,区域分布差异悬殊、变化复杂。密度跃层对海洋科学、舰艇航行及国防建设等都有重要的学术意义和实际应用意义。Based on the collection of 105 years＇ ocean surveying data of South China Sea and the sea area around Taiwan from the year 1900 to 2004,which is analyzed by the resolution of 0.5°×0.5° grid size,and with reference to related marine atlases for hydrology and the Hydrological Analysis and Operational System of China Sea that developed by Atmosphere and Hydrology Center of the General Staff and National Ocean Information Center,the article illustrated the regional and seasonal characteristics of the pycnocline of the entire China Sea and the rule of its variations.The geographic,meteorologic and hydrological condi tions of China Sea show distinct varieties,resulting in various types of pycnocline.The pycnoclines show strong disparity and complexity in regional distribution.The research of pycnocline has significant academic and practical values for oceanography,naval vessels＇ traveling and the constructions of National Defence.
