摘　　要：根据黑潮锋区环境特点及其对海军水声探测的重要影响,建立了指数形式的黑潮锋特征快速重构模型,利用历史数据、实测数据、遥感数据实现了锋区环境参数的快速获取。在此基础上,提出了基于锋面梯度纹理特征的黑潮锋三维体结构可视化方法,实现了对锋区三维空间特征的实时、直观表达。黑潮锋年变化特征的仿真实验结果表明了该方法的有效性。According to the feature of Korushio front and its important influence for underwater acoustic detection of navy, the exponential type feature model of Korushio front was established for rapid environment reconstruction. The environmental parameters of front zone were rapidly acquired by using historical data, surveying data and remote sensing data based on the feature model. The volume rendering method for Korushio front was proposed by using the spatial slope characteristic texture of front. The method gives a timely and intuitionistic description for the spatial structure of Korushio front. Simulation results of front yearly various characteristics show that the method is practicable.
