【摘要】 海底热液区地形复杂度是热液活动场的重要指标数据,获取地形复杂度指标数据,为系统研究全球海底热液区分布特征具有重要意义。本文阐述了地形复杂度和GEBCO数据的基本应用情况,介绍了基于数字地形模型数据进行地形复杂度计算的基本方法,提出了海底热液区地形复杂度计算的窗口序列分析法和基本步骤,实例分析了伊豆—小笠原海底热液活动亚带的地形复杂度情况。更多还原

【Abstract】 The terrain complexity is an important indicator for hydrothermal fields, and it is great significance to study the global distribution of hydrothermal fields. This paper, firstly, describes the basic application about the terrain complexity and GEBCO, the basic methods about the terrain complexity calculation based on DEM. Secondly, the method based on window sequence analysis is put forward about the terrain complexity calculation of hydrothermal fields. Finally, the examples shows the terrain complexity situations about Izu-Bonin hydrothermal activity subzone.更多还原
