中国近海台风强度与水产品产量相关性分析

台风会对海洋水体及生态系统产生剧烈扰动，从而对海洋渔业产生影响。从讨论其影响方式和程度入手，首先对我国近海的台风风速与海洋水产品产量数据分别进行抽象建模，得到信号序列；然后利用希尔伯特-黄变换分别进行变换分解，得到同时间尺度下的信息分量，并对不同时间尺度的两类信号相关度进行分析。结果表明，台风最大风速会对未来一年内的天然海水产品产量产生显著的负向影响；而对于该产量的中长期变化趋势影响并不显著。

Correlation Analysis Between Typhoon Intensity and Marine Aquatic Production in the Coastal Waters of China

Typhoon has an impact on marine fisheries because of their severe turbulence motion to ocean waters bodies and ecosystems, thus the way and degree of the influence are discussed. Firstly, to get the signal sequences, the mathematical model of typhoon wind speed and marine aquatic product output data in the coastal waters of China are established respectively. Secondly, the components of signal at different time scales are obtained by Hilbert -Huang transform. Lastly, the correlations of two kinds of signal components at different time scales are discussed. The results show that, the maximum wind speed of typhoon will have a significant negative impact on the natural production of marine aquatic products over the next year while its impact on the medium-term or long-term change trend will not be significant.
