| 摘 要： | 本文论述了活断层分段中的一些基本概念和主要的边界标志。提出分段的基本原则是：以断裂的不连续性为依据，以地震危险性评价为目的，划分断层段。文中提出了９条分段依据和３９个具体标志。认为地震危险性评价应坚持两条原则：①由定性到定量；②循序渐进，逐步缩小范围和时段。文中提出了利用活断层资料确定潜在地震危险区、估算震级和预测发展时间的方法，其中的一些模型是作者近年来的最新研究成果。认为利用活断层分段进行地震危险性评价具有一定的科学性和实用性，是中长期地震预测的重要研究内容之一。

| Abstract: | Some basic concepts and main boundary marks on active fault segmentation werediscussed in the paper. The basic principles of segmentation were put forward. Nine bases andthirty-nine marks about segmentation were given in the paper. We thought that the assess-ment of seismic risk should follow two principles:a)From qualitative analysis to quantitativeanalysis,b)Proceeding in an orderly way and step by step;shortening a range and time pro-gressively.It is available to make use the information about active faults determines proten-tial seismic area, estimates magnitude and predicts earthquake time. Some of the models areour reseach achievements recently. |
