断层的活动方式、活动强度是反映区域构造应力场状态的重要标志之一。川、滇西部地区是我国构造比较复杂的多震区。近十多年来的精密短基线、短水准测量结果表明,该区构造活动幅度较大,其活动方式也存在一定的规律性,这为构造活动性以及区域应力场的研究提供了有意义的资料。 Fault activity pattern and activity intensity are one of the most important symbols reflecting the state of regional tectonic stress field. Sichuan and western Yunnan are multi-earthquake areas with complicated structures. The short-term and short-term measurements of precision over the past decade show that there is a large range of tectonic activity in the area and a certain regularity of its activity patterns, which provides significant implications for the study of tectonic activity and regional stress field data.
