摘　　要：根据海洋环境资料空间分布的特点,使用Surfer中三角形线性插值法与样条平滑的组合能够比较准确地绘制单航次数据资料的客观分析图。对于累年多源资料,为了较好地解决海洋环境场的各向异性和资料空间分布不均匀性的问题,在Carter(1987)发展的客观分析统计模型的基础上,采用不同的搜索域进行客观分析,取得了良好效果。另外,Kriging方法用于海洋绘图时,在跃层和锋面处容易出现“鼓肚”现象,不能很好地反映浅海区潮混合导致的均匀层,应用时需加以注意。Based on the spati ear interpolation and spline cruise survey data, and in al distribution features of marine environmental data, the combined triangle linsmoothing method can be used to better plot the objective anlysis map of single order to solve the problems with the anisotropy of marin and the nonhomogeneity of survey data distributions, different search are analysis of multi-year and method to the plotting of the thermocline and front water area cannot be well multi souce survey data to get better results. In marine element dis on the map, and reflected, which as are used addtion, in e environmental filed to make an objective applying the Kriging tribution map, the swelling phenomenon is easy to appear at e homogeneous layer caused by the tidal mixing in the shallow ould be taken into consideration in applying the Kriging method.
