| Abstract: | The distributing characters of the recent time space changes of the gravity field in the front region of the Three Gorges project have been analyzed, and the relationships of the fluctuation of the gravity field with the tectonic activity and the changes of crustal stress field have also been studied.Hence at present we consider that the stress field in study region tends to relatively strengthening, and the direction of the regional stress field is NEE SWW. |

| Keywords: | Three Gorges on the Yangtze River change of gravity field tectonic stress field |
