| 摘 要： | 近海底质类型图在近海工程和经济活动中有着广泛的应用价值.针对传统制图方法中存在的问题,提出了一种基于非参数指示Kriging的底质类型图生成方法.该方法能够有效地规避制图过程中的主观性,且对取样数据的平稳性和统计分布没有特殊要求,并能对制图结果的不确定性进行定量评价.该方法在连云港南部海域的应用实践表明,在相同的条件下...

| Abstract: | Coastal surface sediment type map has been widely used in marine economic and engineering activities, but the traditional mapping methods had some shortcomings due to their intrinsic assumption. In this paper, a non-parametric method of indicator kriging has been proposed for generating types and distribution of coastal surface sediment. The method can effectively avoid mapping subjectivity, and has no special requirements for the sample data to meet second-order stationary or normal distribution, and can also provide useful information on the quantitative evaluation of mapping uncertainty. The application of the method in the southern sea area of Lianyungang showed that much more mapping precision could be obtained compared with the traditional methods such as IDW, kriging and Voronoi under the same condition, so the method had some promotion and practical values. |
