| 摘 要： | 为更精确得到三峡地区新构造应力场的分布情况,用GIS技术,对原有水系反演新构造应力场的方法进行了改进,用趋势线代替首末点连线。以MapGis水系数据为基础资料,反演了三峡地区新构造应力场,绘出了主应力迹线图。利用GIS的空间分析,结合基础资料得出三峡地区的新构造应力场以NE向为主。

| Abstract: | For obtaining the neotectonic stress field in Three Gorges region more accurately,an improved method is presented and the line of start and end is replaced by the trendline on the plat of MapGis by utilizing GIS technology.The neotectonic stress field of Three Gorges region is inversed on the base of MapGis river data and the principal stress trajectory is plotted.By utilizing the spatial analysis of GIS and combined it with the analysis on the primary data together,the results show that NE is the main direction in neotectonic stress field of Three Gorges region. |
