Based on a brief summary on the practice of crustal deformation monitoring and earthquake prediction, and combined with the existing research results of regional crustal deformation before the 2001 Ms8.1 Kunlun and the 2008 Ms8. 0 Wenchuan earthquake, this paper elaborates that it is necessary and important to focus on the geological background and tectonic deformation in different layout modes to enhance the ability of seismic deformation monitoring in considering that today the crustal deformation observation technologies continuously advance to high precision, high resolution and efficiency and convenience. Then according to the regional tectonic dynamic background and deformation mode of the southwest margin of the Ordos block, we present and discuss some ideas and methods which can optimize the layout of monitoring and capture the dynamic information of the abnormal surface changes effectively in this key monitoring area.%本文通过对我国西部地壳形变监测与地震预测实践的简要回顾,结合2001年昆仑山口西8.1级、2008年汶川8.0级大地震前区域地壳运动变形背景的已有研究结果,分析阐述了在现今地壳形变观测技术不断向高精度、高分辨和高效便捷发展的趋势下,注重地质构造活动背景和构造变形模式差异布局,提升地震形变监测能力的必要性和重要性.进而根据鄂尔多斯西南缘区域构造动力背景和变形模式,探讨了针对这一重点监视区优化监测布局、有效捕捉地形变异常动态信息的一些思路和方法.
