摘　　要：利用现有的腾冲火山区水平及垂直形变资料进行分析研究 ,结果表明 ,水平形变网覆盖的 2 0 0 0km2 区域内 ,大部表现为面收缩的趋势。马鞍山、来凤山、腾冲县城一带 ,地表基本保持平稳 ,并以此为界 ,其北面大部上升 ,而南部下降。由此说明火山区内地下岩浆仍在运动。Analyses and studies are made by current data of horizontal and vertical observations in Tengchong volcano areas. The results show that the tendency of surface contractility has been observed in most of the areas, which covered more than 2000 km 2. The position of Maanshan, Laifengshan and Tengchong town basically keeps stable, where is a border, most are uplift to the north, and subsidence to the south. It is considered that the magma is still moving.
