在利用远震面波资料研究小区域内的地壳上地幔速度结构时，传统的面波层析成象所依据的大圆路径和平面波入射假设不能成立．本文利用德国区域地震台网记录的Love波资料，根据Friederich和Wielandt提出的面波波场和速度结构联合反演方法，对德国南部地区的Love波相速度横向不均匀分布作了初步研究．反演得到各个周期面波相速度分布的主要特征是稳定的，不随资料选取而改变．30s左右Love波相速度主要受地壳厚度控制，反演得到的相速度分布与该区域已知的莫霍面深度分布有很好的对应关系．39-66s周期的Love波相速度图像随周期逐渐改变，过渡到一个主要受岩石圈下部上地幔构造活动控制的格局．在75-113s周期范围内的相速度分布图像表明，莱茵地堑等构造活动区为明显的低速区．在研究区域东北部的构造稳定地区，从20-113s周期始终显示为高速区．
In the study of the velocity structure of crust and upper mantle in the small area by using teleseismic surface wave data, the assumption of the large circular path and plane wave incident based on the conventional surface wave tomography can not be established. Based on the Love wave data recorded by the German regional seismological network and the joint inversion of surface wave field and velocity structure proposed by Friederich and Wielandt, this paper makes a preliminary study on the lateral non-uniform distribution of the phase velocity of Love wave in the southern Germany. The main characteristics of the inversion of the velocity distribution of surface wave in each cycle are stable, which do not change with the data selection. The phase velocity of Love wave is mainly controlled by the crustal thickness at about 30s. The phase velocity distribution obtained by the inversion has a good correspondence with the known depth distribution of Moho. The images of Love wave phase velocity in 39-66s cycle gradually change with the period, and then transition to a pattern dominated by the tectonic activity of the upper mantle beneath the lithosphere. The phase velocity profiles in the 75-113s cycle show that tectonic activity zones such as the Rhine graben are clearly low velocity zones. In the tectonic stability area in the northeast of the study area, the period from 20-113s always shows as high-speed area.
