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。 Based on the existing horizontal and vertical deformation data in Tengchong volcano area, the results show that most of the 200 km 2 area covered by the horizontal deformation network shows the tendency of surface contracting. Ma On Shan, Lai Fung Shan, Tengchong County area, the basic surface remained stable, and as a border, most of its north rose, while the southern decline. This shows that the underground volcanic magma is still moving.
