1.Additionally, the cost-return structure of Sakura shrimp fishery is absolutely dynamic within a socioeconomic environment.
2.The results are as fallows:1. 98 species of the zooplanktons were indentified preliminarily, of which 29 species belong to Hydzomedusa, 4 species Siphonophra, 2 species Ctenophora, 1 species Cladocera, 46 species Copepoda, 6 species Mysidacea, 2 species Eupbau-siacea, 4 species Sergestidae, 1 species Gastropoda, 3 species Chaetognatha and many planktonic larvae.
3.Its basic principle is to regard selecting or do not selecting a feature as a two-level independent factor; the parameters of SVM as continuous noise factors; the accuracy of the SVM model as the dependent variable; to employ a fractional factorial experiment design to form the experiment which combines the two-level factors and the noise factors; after the experiment is finished, to analyze the effect of each factor to determine the effective independent factor combination, namely the best feature combination for the SVM model.
