Abstract: Global geodetic observing system (GGOS) has been widely applied to monitoring the global change. This paper systematically introduces the method for monitoring and evaluating the regional geological environment stability by comprehensively utilizing multi-source geodetic observations, geological and seismic data. Circum-Bohai-Sea area and Sichuan-Yunnan area as two typical cases are studied to introduce the latest progresses and applications in monitoring and evaluating the regional geological environment stability, where the geological environment of the former is characterized by the subsidence while that of the latter mainly represents the areas with frequent earthquakes. The typical case studies show that, for different geological environment backgrounds, by combining the multi geodetic monitoring data with geological, seismic, hydrological data, regional geological environment stability can be effectively monitored and evaluated. Monitoring and evaluating the regional geological environment stability has been expanding the geodetic applications in global change monitoring, and this work is of important scientific and practical significance.

Key words: geological environment stability, geodetic monitoring, earth surface change, factor analysis method, quantitative evaluation
