英文摘要： The geographic national conditions monitoring is an important mission of the space information science in the new era and regional crustal stability moitoring is a key task in the national project.The assessment on regional crustal stability plays a key role in social and economic development, Earth science and disaster prevention. Towards these demands, employing geodetic techniques and multi-information this project obtains the geometric and physical time-varying characteristic of the regional crustal stability. Moreover, to study the interaction mechanism of the crustal stability with internal and external dynamic factors, the generalized and comprehensive model will be established by identifying and quantitatively analysing the key factors which essentially determine the stability of the crust. At last, the spatial-temporal evolution of regional crustal stability will be revealed by the assessing the stability under different combinations of these key factors and by taking the perturbation factors into account. Keywords: regional crustal stability; key controlling factors; interaction mechanism; mechanical mechanism; comprehensive model.
