| Abstract: |
| Land subsidence disaster has been becoming a serious concernbecause of its increasing hazard to environment and local sustainable development of economy. Turther study on land subsidence is not only necessary for environment but also for scientific exploitation to resources and sustainable growth in economy, which is exspecially important to the eastern area of China, the most populated part of China where mining activitied for oli,gas and groundwater are frequent and natural events,such as tectonic activity,sea level undulation and earthquake commonly.Over-mining and evacuation of the natural resources under the natural agents build up a considerable effect on land subsidence in the region.Various techniques have been used to detect the land subsidence,such as leveling,GPS,In SAR,PSI and GIS ,However,no single-method application is satisfied in real cases. Therefore,integration of multi-sourced data is developed in this paper.In detail,ground deformation detection,data process,problem and prospect in the research are discussed. |
