| Abstract: | In this paper, the map of isostatic gravity anomaly in the northwest of Yunnan province and its adjacent region are compiled by mechanism assumed Ainy-Heiskanen, using the circular model.The relationship between basic characteristic of isostatic anomaly and tectonics within the earth's crust is analysed, and the correlativity between isostatic gravity anomaly and activity of strong earthquake is initially investigated. |

| Keywords: | isostatic gravity anomaly compensating density gravity gradient zone |
