Abstract: The polymetallic nodule deposit is a kind of submarine mineral resources.Except for its two dimension distrihution, heing covered by the thick overlying waters, basic theory and method of submarine mineral resources evaluation, as well as its procedure of exploration and exploitation are similar to those of the land mineral resources.However it should be thought to select mathematical function and to construct theoretical model based on plymetallic nodule deposit. The foundational theory and method of polymetallic nodule resources evaluation has been briefly introduced.The principle and the advantage of the resources evaluation methods such as multivariate statistical method(including cluster analysis,factor analysis and trend surface analysis),geostatistics(Kriging)and neural network analysis(back-propogation method) are respectively described in detail.The application examples and calculation results are given out in the forms of tables or figures according to the theory and method.The software of"Evaluation System of Polvmetallic Nodule Resources"has been developed by authors for realizing the computerized mobile analysis of cutoff indexes( grade and abundance)-resource amounts-deposit area and its program structure is shown in the paper.
