摘　　要：平衡剖面技术是构造演化定量恢复的有效手段,但需根据实际地质条件采取相应的方法才能获得可靠的成果。盆地构造演化的平衡剖面恢复主要包括地质剖面的构建、平衡剖面计算、去压实校正、应变量与应变速率分析4个步骤。平衡剖面技术可以对构造运动进行检验和定量分析,建立模型,对复杂现象做一个可能的解释。将平衡剖面技术应用于兰坪盆地,计算出不同时期地层的缩短量,为下一步研究提供参考,具有构造意义。The technology of balanced section is one of an effective means to reconstruct tectonic movement quantitatively. However, some corresponding methods based on the region geological conditions are necessary for obtaining reliable results. Balanced section restore of basin tectonic development includes four steps： construction of geological section, calculation of balanced section, decompression correction, analysis of strain and strain rate. This method shows some good performance in examining and quantitative analyzing of tectonic movement, modeling, and explaining some complex phenomenon. In this study, the technology of balanced section is used in basin of Nanping. The shortening length in different period is calculated. This will provide some significant background for future study.
