China has been affected by some of the world ' s most serious geological disasters and experiences high economic damage every year. Geohazards occur not only in remote areas but also in highly populated cities. In the framework of the Dragon-432365 Project, this paper presents the main results and the major conclusions derived from an extensive exploitation of Sentinel-1, ALOS-2 ( Advanced Land Observing Satellite 2) , GF-3 ( GaoFen Satellite 3) , and latest launched SAR ( Synthetic Aperture Radar) , together with methods that allow the evaluation of their importance for various geohazards. Therefore, in the scope of this project, the great benefits of recent remote sensing data ( wide spatial and temporal coverage) that allow a detailed reconstruction of past displacement events and to monitor currently occurring phenomena are exploited to study different areas and geohazards problems, including:surface deformation of mountain slopes;identification and monitoring of ground movements and subsidence;landslides;ground fissure;and building inclination studies. Suspicious movements detected in the different study areas were cross validated with different SAR sensors and truth data.

中国和日本都曾经历低生育水平阶段,虽然经历的时间和生育水平下降的原因各不相同,但少年儿童人口绝对数量和占总人口的比重均呈现不断下降的态势,且都不同程度地出现了少子化现象,进而对包括人口发展在内的经济社会发展的很多方面带来了负面影响.研究表明,应根据人口发展态势不断完善相关政策,加快3岁以下婴幼儿照护服务体系建设,促进就业并保持经济良性发展,积极培育老龄产业,大力减轻家庭和社会的负担,以此应对中国可能出现的少子化日趋严重的问题.
