一种近海底质类型图生成的非参数方法

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，本文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，该方法可获得比传统方法更为精确地的制图结果，具有一定的实用价值。

A non-parametric indicator Kriging method for generating coastal sediment type map

Coastal sediment type map has been widely used in marine economic and engineering activities, but the traditional mapping methods had some limitations due to their intrinsic assumption or subjectivity. In this paper, a non-parametric indicator Kriging method has been proposed for generating coastal sediment map. The method can effectively avoid mapping subjectivity, 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 convincing mapping results could be obtained compared with the traditional methods such as IDW, Kriging and Voronoi diagram under the same condition, so the proposed method was applicable with great utilization value.
