InSAR技术进步与地面沉降监测应用——中国科学院院士中国工程院院士李德仁教授接受本刊专访

InSAR: Technological progress and its application to land subsidence monitoring——An exclusive interview with Professor LI De-Ren, Academician of the Chinese Academy of Sciences and Chinese Academy of Engineering

2013年7月26日,上海市地质调查研究院副总工程师兼水土环境研究所所长王寒梅教授、上海市地质调查研究院总工程师办公室副主任兼《上海国土资源》编辑部主任龚士良教授专程赴武汉,拜访了中国科学院与中国工程院两院院士、武汉大学测绘遥感信息工程国家重点实验室学术委员会主任李德仁教授,并代表《上海国土资源》期刊作了专题访谈。李院士详细介绍了中国科技部与欧洲空间局合作的"龙计划"项目的主要研究内容以及业已取得的成果;阐述了卫星遥感监测的技术进步及在资源与环境调查中的应用;针对城市地面沉降问题,指出利用短波段双天线雷达,采用极化方式,通过差分合成孔径雷达干涉测量与永久散射体干涉技术,有助于提高监测精度;重大工程的形变监测,可采用光纤传感器,推广应用精密工艺测量。李院士同时建议,应加强大地水准测量、卫星遥感测量与光纤传感器等技术的融合,以更好地为国土资源研究与管理服务。

Professor LI De-Ren is a well-known international scientist specializing in the fields of photogFammetry and remote sensing, an academician of the Chinese Academy of Sciences and Chinese Academy of Engineenng, and a director of the scientific committee of the State Key Laboratory of Information Engineering in Surveying, Mapping and Remote Sensing at Wuhan University. Professor Li gave this exclusive interview to the $hanghaiLand ＆ Resourcesjoumal on the altemoon of 26 July 2013. Dunng the interview, Professor Li detailed the main components of the Dragon research program run by the Chinese Ministry of Science and Technology in cooperation with the European Space Agency. He also summanzed the results already achieved, and explained recent technological progress in satellite remote sensing monitoring and its application to resource management and environmental surveying. In view of ongoing issues related to urban land subsidence, he pointed out that monitoring accuracy will be improved by the use of short wavelength double-antenna radar together with the polanzation approach and differential interferometric synthetic aperture radar （InSAR） and permanent scatterer interference technology. Professor Li also discussed the increased use of fiber optic sensors for deformation monitoring dunng major projects, and the application of precision measuring processes. Furthermore, he suggested that technologies such as geodesic leveling, satellite remote sensing observations, and optical fiber sensor technology, if further developed so that they can be used cQUabQra0vely, would benefit both research and management of land and resources.
