| 摘 要： | 借助GIS ArcView软件分析提取黑潮锋区域,将一定间隔的经纬度点的温度值生成等值线以此为研究对象,应用网格法计算了20°～30°N,120°～130°E范围内黑潮锋区50m和100m深处水温的分维值,100m深处的分维值波动较50m深处小,但整体上分维值较50m深处大。计算结果符合黑潮锋区强度的实际分布情况,初步认为分形维数能够表征黑潮锋强度,分维值随黑潮锋强度的增大而增大。

| Abstract: | The Kuroshio will affect sonar detection greatly.The intension of Kuroshio is always concerned by the submarine commanders.Gis ArcView is used to identity the Kuroshio area from underwater acoustics data.The seawater tempreature isolines are drawn based on the temperture data which is distributed by some interval.Appling the box counting method,it is calculated that the fractal dimension of the seawater temperture isolines of the Kuroshio at different times at 50 m and 100 m deep.The conclusion is given that the fractal dimension is bigger at 100 m deep than at 50 m deep,but the former waves less than the latter.It is accorded to the factual Kuroshio.So the fractal dimension can be used to describe the Kuroshio and the fractal dimension will become larger while the the Kuroshio.becomes intenser. |
