Using matched-filter method,the geomagnetic anomaly data from profiles of Luan-Yingshan（Ⅰ）,Baitafan-Wuwei（Ⅱ） and Jinzhaiqingshan-Wanfuhu（Ⅲ） in Eastern Dabie Orogenic belt are processed,the local anomalous field is extracted from regional field.Based on regional anomalous field,the buried depth of Curie surface along profiles are calculated using the approximate linear invertion method.Combined with the geological results and earthquakes distribution in this area,the relations between seismic activity and Curie surfaces,and the seismogenesis mechanism are researched preliminarily.The results show that the curves of geomagnetic anomaly exhibit the various characteristics and differences of structural basements of different profiles,existing apparent mirror image relationship with the depth of Curie surfaces.Fluctuation of Curie surface in the area is about 14 km,the lowest position is at Huoshan,where is the intersection part of profile Ⅰ and Ⅲ.The corresponding relation between earthquakes distribution and Curie surface is apparent,most earthquakes occur on gradient zone of Curie surface.Thermal stress generated from temperature difference of gradient zone might be direct dynamic sources of Houshan area.The invertion result of Curie surface provide proof for offset on Moho along Xiaotian-Muzitan Fault.
