Through a systematic summary of the new trends and measures in these strategies and plans, this paper reveals the new tendency of global geological surveys, which is manifested in the following six aspects:① geological survey around the world is facing huge challenges of transformation and upgrading; ② using digital technology revolution to reshape the development of geological survey has been raised to the height of strategic development; ③ promoting the coordination of man-earth relationship has become an important content of geological survey; ④ multi-factor monitoring network system is becoming the basic condition for geological survey to realize high level development; ⑤ geological mapping is more problem-oriented, target-oriented and application-oriented; ⑥ geological survey is speeding up its regionalization and globalization. Besides, in order to promote the transformation of geological survey in China, this paper puts forward four aspects of suggestions, i.e., expanding work area, speeding up data integration, strengthening comprehensive study, and enhancing monitoring capability.
